As a hair loss treatment that is similarly (if not more) effective than minoxidil, peppermint oil is a necessary addition to your hair care routine if you want to stop any further thinning and receding and perhaps even regrow your hair.

This guide will discuss the use of peppermint essential oil (PEO) for the treatment of hair loss. This includes an in-depth look at recent scientific research, as well as ways you can use the ingredient more effectively.

What is Peppermint Oil?

Peppermint is a plant hybrid of spearmint and watermint, and it is used in a variety of industries.

In addition to its place in the kitchen (where it is added to tea, gum, ice cream, and more), it is also been used quite recently for its many health benefits.

Peppermint has been shown effective in relieving hot flashes in women, reducing symptoms of irritable bowel syndrome, and decreasing nausea (1, 2). Due to its cooling effect, it is used commonly in the temporary treatment of muscle and nerve pain, as well as in the relief of itching (3). In addition, its aroma is frequently used to induce alertness.

Can PEO Be Used to Regrow Hair?

There is no doubt that PEO is a highly versatile ingredient. But where does it stand when it comes to treating hereditary baldness?

As will be discussed further below, PEO has a variety of properties that make it an excellent addition to anyone’s hair regrowth routine.

This article will highlight four main properties of PEO that help in the regrowth of hair, including:

  1. Stimulation of the anagen growth phase;
  2. Improvements in blood supply;
  3. Anti-fungal and anti-bacterial properties; and
  4. Anti-inflammatory properties.

More Effective Than Minoxidil?: The Scientific Proof

In 2014, Korean researchers studied the effects of PEO on hair growth (5). Comparing the essential oil to Minoxidil, a popular FDA-approved hair loss treatment, the results were certainly stunning.

Though, it needs to be remembered that this study was conducted on shaved mice, not humans. More studies are needed on humans for more conclusive results. However, since human studies are, understandably, considerably more expensive than mice studies, we might be waiting a while for those.


In the beginning of the study, 20 male mice were shaved on their dorsal area so as to standardize the telogen phase for all. The mice were split into four separate groups, with each group receiving a topical application of either:

  1. Saline (SA);
  2. Jojoba Oil (JO);
  3. 3% Minoxidil (MXD); or
  4. 3% Peppermint Essential Oil (PEO)

The application was done six days per week for a total of four weeks.

Throughout the study, photographs were taken to visually track hair growth. Each photograph was categorized, and the categories were as follows: 0: no hair growth; 1: less than 20% growth; 2: 20% to less than 40% growth; 3: 40% to less than 60% growth; 4: 60% to less than 80% growth; and 5: 80% to 100% growth.

In addition, skin biopsies were taken at conclusion of the study, and a number of RESULTS were tested.


As mentioned, photographs were taken every week throughout the 4-week study.

The effects of saline, jojoba oil, minoxidil, and peppermint oil on mice

As clearly depicted, saline and jojoba oil had minimal visible results throughout the course of the study. However, minoxidil and PEO saw positive hair growth from week 2, and this continued through the entire four weeks.

Further, PEO was clearly dominant when compared with minoxidil and growth was still ongoing. This means that both groups of mice were in the anagen phase of hair growth even after four weeks.

Hair growth phase is important to understand the reasons behind hair loss

Now, while visual results can be helpful, it is important to get a better understanding of the scientific results obtained by biopsies and samples. First is a chart that graphs the effectiveness of all four groups over the course of the study. The results were the mean hair growth score of five mice in each group:

While PEO and MXD were close in the first week, PEO quickly took the lead in terms of hair regrowth scores. In fact, the gap between the two treatments only continued to widen as the weeks passed to reach 60% at the end of four weeks between PEO and MXD.

Next, here is a look at the biopsy results. Here, we see the vertical histological view depicting the quantity and quality of hair follicles:

Only minoxidil and PEO showed clear hair growth, as depicted by the elongated hair follicles and hair shaft.

Last, researchers compared the number of hair follicles in all four groups, as well as the depth of said follicles:

By week four, the PEO group had seven times and three times more hair follicles than the SA and JO groups, respectively.

In addition to all of the above results, PEO was also shown to increase blood circulation to the scalp. This was determined by monitoring Alkaline Phosphatase (ALP) activity. When ALP activity is increased, the relaxation of vascular smooth muscle occurs. This enables improved blood flow, and enables your hair follicles to receive the nutrients and oxygen it needs to stay healthy.

As concluded by researchers, “PEO effectively stimulated hair growth in an animal model via several mechanisms and thus could be used as a therapeutic or preventive alternative medicine for hair loss in humans.”

The Oxygen-Hair Loss Connection

Peppermint oil can increase blood flow when applied topically. As such, it also increases the delivery of oxygen and nutrients.

Oxygen, as it does in all other organs, plays a crucial role in the hair follicle. It not only keeps it alive, but it also provides the scalp with circumstances necessary to thrive. Let me explain.

When testosterone is produced in the prostate, it does not stay there. Instead, it travels to various parts of the body (including the scalp and hair follicles). This is known as Free Testosterone (fT) (6).

When fT makes its way to the scalp, it meets another substance – 5AR (7). If the circumstances are right, as they often are, this interaction will result in the production of DHT. While this is okay for individuals without Androgenetic Alopecia (AGA), it can lead to inflammation and miniaturization in those with the condition.

Oxygen plays a role in the scalp’s environment. In short, a low-oxygen environment will contribute to the production of DHT. This is because very little oxygen is needed for the exchange.

If you have AGA, this will only continue the cycle. The presence of DHT = miniaturization = less blood flow and poor oxygen levels = hair loss. However, you can increase the oxygen levels (with natural extracts such as peppermint oil) to create a different outcome.

This outcome, another by-product of fT and 5AR is estriadiol, an estrogen steroid hormone that has actually been shown to induce hair growth (8). By increasing oxygen levels, then, you will see a decrease in DHT production and an increase in estradiol.

Implications for Thin Hair Sufferers

While the above study was performed on mice, the results can have serious implications for the future treatment of hereditary baldness.

As shown, PEO plays a key role in the initiation of anagen phase and hair follicle proliferation. Both of these are necessary for the growth of healthy, strong hair.

In addition, it also markedly increased IGF-1 gene expression at week two, where it took minoxidil until week four to do (9). What does this mean?

The IGF-1 gene is one that promotes cell growth and survival, and also increases the thickness of hair. An increased expression of this gene means improved hair growth. In individuals with AGA and other such forms of alopecia, this can mean that the use of PEO can “reboot” the hair growth cycle.

Additional Benefits of PEO

The above study does show some promising results, but PEO is beneficial to thin and receding hair sufferers in a number of others ways, too.

First and foremost, this nice smelling herb belongs to the same family as rosemary. This is another oil that is beneficial in the treatment for regrowing hair, and this connection may indicate more positive benefits for PEO than just what the above study shows.

In addition, PEO has benefits that are not just related to scalp health. However, these benefits can still provide your scalp and hair with positive effects.

It Cleans the Scalp and Follicles

Scalp buildup – including sebum, sweat, dead skin, hair product, and even chemicals such as DHT – can create an unhealthy environment for your hair. This can lead to irritation and inflammation, and it can also encourage the growth of bacterial and fungal infections.

PEO is an effective antimicrobial, fighting both bacteria and fungi (10).

This was proven in a 1996 study that tested the efficacy of ten different essential oils against 22 bacteria and 12 fungi. The oils included in the study were aegle, ageratum, citronella, eucalyptus, geranium, lemongrass, orange, palmarosa, patchouli, and peppermint.

The oils were introduced to the various bacterial and fungal cultures, and here is how peppermint oil fared. Peppermint was effective in inhibiting all 22 of the bacterial strains, as well as eleven out of twelve of the fungal strains.

Whether you suffer from tinea capitis, dandruff or seborrheic dermatitis, or folliculitis, PEO can clean the scalp and treat the issue at its source. This means you can provide a clean and healthy environment for your hair follicles, and this in itself is a necessary step when looking to regrow your hair.

It Soothes an Irritated Scalp

The conditions mentioned above – such as dandruff and folliculitis – can cause irritation and inflammation. Not only is this uncomfortable, but it can also lead to inflammation, scarring, and permanent bald spots.

PEO’s main component, menthol, is a known anti-inflammatory.

This was shown to be true in a 2016 research study, which aimed to determine whether menthol could be used to 1) treat a parasitic infection; and 2) soothe the symptoms of said infection (which include inflammation of the skin) (11).

The mice in the study were infected with the parasite, and then split into five treatment groups. These were:

  1. Negative control (which was not infected with the parasite);
  2. Positive control (which was infected with the parasite, but not treated);
  3. Mentha 15 (which were treated for 15 consecutive days with 50mg/day);
  4. Mentha 60 (which were treated for 60 consecutive days with 50mg/day); and
  5. Praziquantel (a drug commonly used in the treatment of the infection).

NOTEThe menthol in this study was derived from a pharmaceutical source – Mentaliv, which is commonly used to treat Irritable Bowel Syndrome (IBS) – and it wasn’t the only component within the Mentha 15 and Mentha 60 treatment groups. Another major component was methone, which was up to 32% of the solution.

One way to test for inflammation is by studying cytokine levels (12). These are pro-inflammatory proteins, which have a direct effect on inflammation and pain. Here is a look at this groups’ cytokine levels after 61 days of infection (and treatment):

The cytokine levels in mice after menthol treatment

As seen above, the Mentha 60 experimental group gave the best results when compared with the positive control. In fact, IL-4 levels were reduced by 53.5% in comparison to the positive control, and IL-10 levels were reduced by 62%.

This anti-inflammatory property was also confirmed in a 2001 study when PEO reduced allergen-induced histamine release (13). Histamine is the chief cause of allergy and inflammation in our body.

This oil’s anti-inflammatory properties, then, may be able to effectively soothe an irritated scalp and prevent further irritation and inflammation from reoccurring.

It Increases Subcutaneous Blood Flow

As mentioned in the 2014 study, PEO promotes blood flow. This was seen by monitoring ALP activity.

The main cause of hair loss in men and women with AGA is the presence of DHT in the follicles. This leads to a process known as miniaturization, which causes inflammation and irritation. When this occurs, another side effect also sets in – a reduction of blood flow to the area.

This happens because the hair bulb – the base of the follicle and the source of nutrients – is separated from the blood vessels due to the swelling. The follicle is then unable to receive adequate oxygen and nutrients, both of which are necessary for healthy hair growth.

One study, performed in 2016, showed that menthol (the main component of PEO) increases subcutaneous blood flow when applied topically (14). In fact, the higher the concentration of menthol the greater the increase in blood flow as measured by Cutaneous Vascular Conductance (CVC):

Menthol increases blood flow

This means that applying PEO to the scalp can naturally reduce inflammation while also increasing blood supply.

How to Use PEO in the Treatment of Thinning Hair

The best (and safest) way to use peppermint oil in the treatment of thinning hair is in shampoos and scalp elixirs. Do not apply any essential oil directly to the skin, they are meant to be diluted.

As an essential oil, PEO should be thoroughly diluted before applying to the skin. This will greatly reduce the risk of skin irritation, while also ensuring that the peppermint oil is more effectively delivered to the hair follicles. However, properly diluting PEO can be difficult without the right equipment, so you will need to be careful when using it.

Are There Risks or Side Effects Associated With Peppermint Oil?

PEO should not be used if you have any liver or bile-related diseases (gallstones or bile duct obstruction). Also, its safety in pregnant women has not been tested.

While rare, side effects may occur when PEO is applied to the skin. You should test the oil on a small patch of skin (such as the inside of your wrist) before applying to more delicate areas (i.e. the scalp). If you do experience irritation, the most common signs include:

  • Burning/stinging
  • Redness
  • Itching
  • Flushing of the surrounding skin

If you are allergic to peppermint oil’s active ingredient – menthol – you should avoid the use of PEO completely. The signs of an allergic reaction include:

  • Itching
  • Redness and/or hives
  • Coughing and/or wheezing
  • Difficulty breathing
  • Nausea/vomiting/diarrhea

While itching, redness, and hives may reduce over time (though, you should keep a close eye on these symptoms, too), you should seek out emergency medical help if you experience any of the other symptoms. Do not take essential oils internally.

The Dermaroller – A Natural Way to Boost Peppermint Oil’s Effects

The dermaroller is a microneedling tool that inflicts tiny wounds onto the scalp. These wounds are deep enough to stimulate new cell production and boost blood circulation, but cause no pain (15).

A man with a large bald spot receiving microneedling

It is recommended to combine this technique with a hair growth boosting ingredient, such as PEO. This will improve the absorption of the oil and, therefore, boost the results.

IMPORTANT! Be sure you leave at least 12 hours between microneedling and applying the oil – otherwise it will sting really badly!

Hair count increases dramatically by using a dermaroller.
Source. Dramatically increased hair count after 12 weeks of using the dermaroller compared to minoxidil alone. And when we consider that PEO is more effective than minoxidil, it becomes clear that PEO + dermaroller would be a powerful combination.

You can see a professional to have this treatment done. However, it is also possible to do it on your own. A few tips for successful use:

  1. Apply the right amount of pressure. You want to apply enough pressure so the needles penetrate the skin to the dermal layer, but you don’t want to cause pain or excess bleeding. Press just until you feel a slight tingling.
  2. Use a multi-directional method. For best results, you want to cover as much of your scalp as possible. This is why it is recommended to use a multi-directional method, including vertical, horizontal, and diagonal.
  3. Wash and sanitize after each use. Allow the dermaroller to sit in an antibacterial wash for at least one minute after each use. Then, rinse, dry, and put away in a clean container. Doing this each and every time will reduce the chances of an infection.

NOTE: The dermaroller should be used prior to application of the oil, but allow the scalp to rest for at least 12 hours before applying the oil. While this may seem like a long time, the effects of microneedling are present even days after the procedure.

Costs and Availability

As a common plant, the oil is widely available and very affordable.

This oil can be purchased in grocery stores, health food stores, and even chemists. In addition, you can purchase the oil online from a wide variety of retailers, including Amazon.


If you are in need of a soothing, cleansing, all-natural product, then peppermint oil may be just what you are looking for.

This is because not only is it seemingly effective at treating hair fall caused by AGA, but it may also treat and prevent thin-hair-causing infections and conditions (such as seborrheic dermatitis) and reduce inflammation.

  1. Great website!!

    I’ve never heard of using Peppermint Oil. Is this something I can put in before bed and wash out in the morning?

    Thank you,

    1. Hi Justen. Yes probably your best option is to add 15ml of peppermint oil to 200ml of magnesium oil (you can also add rosemary oil if you want) and then massage a small amount into the thinning/receding area of your scalp before going to bed. You’ll then have to rinse it out in the morning otherwise your hair will look greasy but that’s the most simple and effective way to use it.

      1. Hi Will
        This is the most informative website that I have found too. Just to follow Justen’s comment – how many times a week would you need to apply the above ? I’m a 44 year old female that has recently had an ovary removed and seen an immediate effect on my hair, though it has been thinning for sometime ):

        1. You can use it every night. If you also use a dermaroller then skip it on the day you use the roller (or it will sting!)

  2. Great information ok so too early to tell i do not have full blown MPB i have thinning and a not so bald spot on the scalp, i used lots of fat burners ephedrine base and stims to lose weight so that is partially due to this. I bough peppermint oil apply twice per day with jojoba oil, also leave in conditioner herb, magnesium oil and i am waiting for melatonin oil. I also take saw palmetto and pumpkin seed oil, i tried dutastiride and minoxidil with terrible side effects, gained lots of weight water etc,,, i also use DIM this time around for estrogen control so far so good no weight gain.

    1. Hi Yannick, I hope it goes well with your mixture. But remember, any topical treatment will have only a limited effectiveness. To truly reverse MPB over the long term you will need other approaches such as diet and lifestyle changes, otherwise you will continually be fighting a losing battle.

  3. I thoroughly enjoy using peppermint oil on my scalp, I do this daily and my hair has grown much thicker and there is more of it. It smells nice and fresh and would recommend it to anyone who’s having hair loss problems.

    1. Hi Will
      The study is conducted on rats and I don’t think they have pattern or genetic baldness like humans. Are essential oils better in treating pattern baldness or Minoxidil and Formula 82F or 82M is better.

  4. Hey do you reckon I could mix peppermint oil in with an organic shampoo base and make my own mix – leave it on for about 10 minutes?

    Was also thinking of adding caffiene powder to the shampoo.

    1. Yes you certainly could. But make sure whatever shampoo base you use, it needs to be very gentle if you plan to leave it on for 10 minutes. The last thing you want to do is strip away too many of the protective oils from the scalp using a harsh cleansing agent. I personally just use apple cider vinegar once per week to wash my hair. I use PEO along with magnesium oil in a scalp spray.

  5. Thank you Will, this is a really good article and I like how you’ve used scientific studies to backup your claims. It is quite encouraging that PEO beats minoxidil. And much less side-effects I’m sure.

    1. Thanks for your comment Jason. Yes I’d much rather use PEO over minoxidil even if they were equally as effective. Given PEO is actually better, now there’s 0 reason to use Rogaine anymore.

  6. I have already used Minoxidil 10%for 1 and half years but It has not worked for me ,so i quit using it as i end up losing more hair and got much more dandruff on scalp.
    so can i use peppermint oil alone everyday for treating MBP ? I’m diagnosed with seborrheic dermatitis too.

  7. Hi Will,
    I am experiencing female pattern hair loss. I am excited to try all these techniques you described on your page. However I am not sure which to start with first. Is there a particular order I should go by? For example, shampoo, then dermoroller, then massage? Also, how often do you recommend I do all these techniques per week? Thanks so much

    1. Hi Janet,

      You can start to use the three techniques you mentioned at the same time.

      We recommend you dermaroll once per week, massage daily for 10 – 15 minutes, and shampoo just 2 – 3 times per week.

      – Steph

  8. I’m 45 years old and started thinning and balding 3 years ago. My main concern with minoxidil is that after using it the hair can’t grow by itself anymore. Does this solution have the same or similar side effects?
    Thank you for your anwser and the time you put into creating this blog!

    1. Hi Izabela, yes after using and then discontinuing minoxidil people often experience shedding where hairs that have been saved or regrown due to the minoxidil fall out and you’re back to where you would have been if you’d never used it at all. I am not sure but I would presume something similar would happen with PEO.

      Luckily however, there is something you can do to stop this happening, and that is to change your body internally so that any new hairs grown will stay there. This is why diet is so important. Because if you don’t change your diet you’ll always be fighting a losing battle with any new hairs grown from topical applications like minoxidil or PEO. As a quick example, perhaps you do an allergy test and find out that gluten is causing you problems and causing inflammation which then leads to hair loss. You remove gluten from your diet and get rid of the inflammation. Then new hairs grown with topical applications will be much less likely to fall out after discontinuing the treatment.

      You’re just using the topical treatment to stimulate new growth, but to keep it there you need to change your body chemistry internally.



  9. Is it true that you cannot use any oils on your skin when you are on oxygen. Is that true.

  10. Hi Will, is PeO dangerous for hair in the same way as minoxidil? PEO is natural unlike minoxidil therefore we can fairly confidently say that the chances of negative side-effects are less. I have personally found this to be true, having no negative side effects from using PEO on my scalp (whereas I did with minoxidil products.)

    1. Hi Farnoosh,

      There are still many unanswered questions when it comes to natural treatments and their long-term side effects. This is because they’re not required to undergo such intensive testing as is minoxidil, or other FDA-approved medications.

      There is a likelihood that minoxidil and peppermint oil work along different pathways and, as such, PEO won’t have the same (or as severe) of side effects. But the fact that you’ve been using PEO yourself with no negative side effects is a great sign.


  11. Hi Will,

    I have made my own mixture that I have started using in my hair after I shower. It isn’t greasy at all and the smell dissipates after it dries. In a small bottle I put half water and the other half ACV then a few drops of peppermint oil and a few drops of Lavender oil as well as one drop of tea oil. Basically the ACV mixture cleans my scalp and the oils increase blood flow to my hair follicles. Simple, cheap, and I believe effective. Love to hear what you think?

    1. I like the recipe. 100% natural and each ingredient has its place. Consider adding rosemary oil for its ability to inhibit 5AR.

  12. Hi, How long should the needles be of the dermaroller? Does your program equilibrium contains GRO2? Do you have an email?

    1. Hi Eddy, the dermaroller in the primary study that we quote use 1.5mm needles. However this is on the longer side of our preferences. I now recommend using a 1mm dermastamp. From 0.5mm to 1.5mm will have an effect so it’s basically personal preference between those sizes.

      Hair Equilibrium is a digital product, so nothing is shipped. However it does include recipes for your own hair growth elixirs. I do have an email but I prefer to respond to questions on the blog, since then everyone can benefit from the discussion.

      1. Hi Will,

        How often should I use dermaroller with needles 0.5 to 1.5?

        thank you

        1. Hi Rania,

          We recommend once per week using a dermaroller with needles between 1 and 1.5. There are some people who use a smaller needle (0.5) at a more frequent rate (2 – 3 times per week). There’s not necessarily a “right” way as long as you give you scalp time to heal in between sessions.


  13. Hi I’m using PEO mixed with Aloe Vera. It definitely feels good in my hair but I am shedding lots. These hairs are thin and dry. I had been on Minoxidil 2 years back which left alot of my hair in the telogen stage, that is dry, thin and different colour. Do you think the PEO is responsible for this shedding? I can easily pull out some now.
    PS i also started Saw Palmetto recently

    1. Hi Dave, it’s hard to say what has caused the shedding. I would make sure the concentration of PEO isn’t too high. perhaps 5% PEO and the rest could be aloe vera if you choose that. Have you stopped using minoxidil? This could cause the shedding.

  14. Hi Will,
    I want to make PEO shampoo whose recipe you showed in this post(with ingredients Apple Cider Vineger, Jojoba Oil, Rose mary, water, ). My question is can I add few drops of rosemary oil instead of Rosemary bunch in water as it is difficult to find the Rose mary plant in my area

    1. Hi Adnan, yes it would be absolutely fine to use rosemary essential oil instead of a bunch of rosemary – and much more convenient.

  15. I’m trying to replicate the study of PEO vs minoxidil. On day two. So, we’ll see how it goes in comparison

  16. Can I keep the magnesium oil and peppermint mix on my hair for 2-3 days straight in between shampooing? thanls

    1. You could, but it can make it look unclean. So you probably wouldn’t want to unless you didn’t have to go out.

  17. 12h to wait after dermaroller?
    So should we use some kind of oil immediately after dermaroller or just leave it?

    1. It’s up to you. There are a few good options. But you have to be careful, some lotions will sting a lot if you put them on straight away after using a dermaroller. Emu oil is a good option though.

  18. Hi Will,
    I got my peppermint and magesium oils a few days ago and put them together but when looking into the bottle it seems as if the two oils dont mix, but stay as two different layers. Should it be like that?
    I shake the bottle before spritzing it on my hair for now.

    1. Hi Tadija, yes you’re right, the two are immiscible. That’s why you must make sure you shake it thoroughly before spraying. There are ingredients that can be added to make them mix completely and stay mixed, but since we don’t want to be adding additional ingredients that don’t promote hair growth, and could potentially cause harm, we decided to leave them out of our formula. After all, shaking the bottle a few times before spraying is easy enough.

  19. Hey just wondering if peppermint oil mixed with coconut oil would be fine or if magnesium oil is the best to mix with.

    Also, how long should the mixture stay on your scalp for? Does it have to be overnight?


    1. Hi John, in general the longer the ingredients are in contact with the scalp, the better. Coconut oil can be good, but it’s easy to overuse and then just make the hair oily. It can also have quite a strong smell, if you are planning on using it overnight.

      1. Thanks for the reply – I’m curious why other than a potential lack of magnesium in diets do you recommend magensium oil as a carrier. Are the listed oils all safe for everyday use? I’m looking for a non greasy oil – Is magnesium a good choice/are all the listed carrier oils as effective?

        Also, the study say PMO 3% – what is the 3% referring to?

        1. Hi Jhon, magnesium oil works particularly effectively transdermally, and since it is applied to the scalp, right where we want to reduce calcification this does help to reduce calcification more effectively than supplementation alone. Yes they are safe for everyday use. Mag oil is not really greasy at all actually. It only has a slight oily texture, but in reality it’s not really an ‘oil’ at all. There are some other carrier oils that could be reasonable replacements, but we have found mag oil to be the best. The 3% is referring to the concentration by volume of PMO in the solution.

  20. i am 18 and i have severe hair loss i think i am in norwood 2 or 3 how can i regrow my hairs can i grow hairs with peppermint oil and magnesium oil without using derma roller

    1. Hi Harpreet, you don’t have to use a dermaroller, but it does help. Keep in mind though that topical treatments have limited effectiveness. You need to get to the real root cause of your hair loss, most likely your diet and scalp tension.

  21. Hi Will,
    I have just started to apply a mixture of peppermint , magnesium and rosemary oil. It’s only been 10 days now and feels good.
    I was recommended by one of my friend to use castor oil.
    Can I mix castor oil in my mixture or apply before bath? Or will it be any helpful.
    Thanks in advance.

    1. Hi Brian, you could try mixing in castor oil, but it will get sticky and messy quite easily. I probably wouldn’t, but if you want to try it once or twice and see how it feels then that is probably worthwhile. You can learn more about castor oil here.

  22. Dear Sir,

    A great site! Thanks for helping so many of us. My question is with regards to peppermint oil. I have read in various articles that peppermint oil is a vasoconstrictor! It is used as a mild anesthetiser! Will it not mean that it will cause blood vessels to narrow and cause more hair loss?


    1. Hi Umang,

      Thanks for reaching out!

      You’re right that a few studies have indicated peppermint oil as a vasoconstrictor. However, the main component of peppermint oil, menthol, is a known and well-studied vasodilator. Menthol can make up a significant amount of PEO, upwards of 40%, which is why the oil is known for its vasodilating effects when applied to the skin.

      Kind regards,

  23. hi i heard that a lot of these oils that battle hairloss also can have negative side effects like losing you’re libido permanently sometimes . i read that about saw palmetto and . is that the same with peppermint oil? these stories are also the reason i am reluctant to buy you’re product because it has those oils in it. i would love the stop my balding but if the chance of those negative side effects are true then i don’t know if its worth it.

    1. It depends which oils we are talking about. Often supplements that help with baldness work by blocking DHT, this could also affect your libido. But peppermint doesn’t work this way, it doesn’t block DHT so I doubt this would be one of the side-effects. Basically the only side-effect we hear about with PEO is light itching. Topical treatments are also much less likely to have side effects than ones that are taken internally such as saw palmetto and pumpkin seed oil.

  24. I’ve read quite a bit about castor oil as well, does it really work? I’m going to give peo a go regardless

  25. Can I use Rogain & peppermint oil both?
    I am planing to get peppermint oil, jojoba oil & rosemary extract. How do I mix that?(how much should be each oil)
    Thank you in advance.

    1. Hi AD,

      You can use them together, though Will strongly recommends weaning yourself from Rogaine over time (while continuing with the natural oils). You should also use them at least 6 hours apart (for example, use Rogaine in the morning and the oil mixture at night).

      A good rule of thumb is 90% carrier oil (such as jojoba or magnesium), 6% peppermint oil, and 4% rosemary oil).

  26. When we apply oil on the scalp, will it clog the pores ? must i wash the hair after 1-2 hours applying the essential oil ?

    Do you sell the pre-mix ?

    1. Hi,

      There are certain oils that can clog the pores, but the ones we recommend do not. With essential oils (such as peppermint), you must combine with another (such as magnesium).

      You can leave it on overnight, and then rinse in the morning (with water).

      We do sell a pre-mix, known as Scalp Elixir:

  27. Hi. I have done something really wrong: I used an increased quantity of peppermint oil combined with the magnesium oil and I now have a urination problem. Is there anything I can do?

    1. Hi Liviu,

      It’s very unlikely that the increased amount of peppermint oil has caused the problem. I would highly recommend seeking help from your doctor.

      – Steph

  28. If I were to mix peppermint oil and rosemary oil into a store-bought shampoo, how much of each would you mix in? Thanks!

    1. Hi Caleb,

      I know Will would strongly recommend you combine peppermint oil (6%) and rosemary oil (4%) with mineral oil (90%) instead. You can certainly add those oils to store-bought shampoos if you like (in those ratios), though we can’t be sure it’ll have much effect.

      Store-bought shampoos aren’t good for applying oils, as they don’t truly penetrate the scalp.

  29. Hello,
    I was wondering how many times a week I should use PEO + plus other oils like castor oil (with the dermaroller procedure) to increase my hair growth?
    Thank you in advance!

    1. Hi Dani,

      The dermaroller shouldn’t be used more than twice per week (preferably 6 days between sessions), and peppermint oil shouldn’t be used immediately after a session.

      You can apply a mixture of magnesium oil (90%), peppermint oil (6%), and rosemary oil (4%) each night. However, you should wait at least 6 hours after dermarolling to apply it.

      – Steph

  30. Hey I been reading alot about onion juice for hair growth or to thicken and strengthen hair due to the high sulphur count. I was wondering what your thoughts are on using onion juice for growth? Or your thoughts on the importance of sulphur for hair loss? …Also would it be good to add rosemary oil, peppermint oil and tea tree oil to it for better results. Especially peppermint oil not only due to its abilities but also to try and mask the smell because alot of people complain about how the smell stays in their hair

  31. Thanks for the reply, i appreciate it. Sorry I have a few more questions if you don’t mind answering… Should I add magnesium oil, PEO oil and rosemary oil for a hair mask and also add jojoba oil and grapeseed oil for the carrier oils to the mask? …I have all these oils at my house and read good things about them…Is there any particular order I should be mixing these in? Not sure what oil to mix in first or if you mix them all at once? And would you happen to know or can estimate what amount of each I should use? Also how many times a week I should do this? Should I wash my hair after each time? ….Im also gonna derma roll and like you say wait atleast 12 hours after to apply the oil masks… Sorry for all the questions, just want to do this right

    1. Hi Jesse,

      You can use all of those oils at once, though I recommend you keep it simple:

      Magnesium oil (90%)
      Peppermint oil (6%)
      Rosemary oil (4%)

      You can apply each night, and then rinse off in the morning with water only.

      – Steph

  32. How’s it going Will nice article. I started my hair journey again about 2 months ago with minoxidil (foam) and derma roller, little hairs have grew on my temples, I believe the derma roller plays a big part. However, minoxidil always leaves my hair kind of white every time I finish shampooing even after I apply by itself in the morning, it’s still residue just building up from it I’m guessing. In my household we always have plenty of natural oils and I always use it on edges/sides burns and it regrew my edges. The other day (Sunday) I wanted to test something new I decided to mix Castor oil, jojoba oil and peppermint oil and apply it to my edges for some reason more hair grew quickly and little hairs just came out of nowhere. To be honest I want to ditch minoxidil and start using oils only with dermaroller. If I leave minoxidil and start using the natural way will I lose anything I gain from minoxidil? And do you think I should just make that choice and stick to that peppermint oil mixture?

    1. Hi,

      You may experience some light shedding, though this can be reduced in two major ways:

      1. Wean yourself off of the minoxidil. For example, begin to use it every other day, and then after two weeks every second day, etc.
      2. Begin to use the natural peppermint oil mixture while you’re still using minoxidil. We recommend applying the minoxidil in the morning, and the natural mixture at night.

      – Steph

    1. Hello Saransh, no! You need to dilute it with a carrier oil before applying it. It is too concentrated to be applied directly.

  33. Thanks for all the great information. I have severe FPB. I have been applying a mixture of castor oil, jojoba oil, peppermint oil, rosemary oil, lavender oil, chamomile oil, and cedarwood oil. Sometimes I leave it on for a few hours or overnight. How long / often do you think I have to do this before I see results? I’m really desperate to see results.
    Also, I know that you mention changing diet and lifestyle…. do you have any particular recommendations for a diet that helps to fight FPB?

    1. Hi Anna,

      The length of time it will take to see results will vary by individual, however topicals alone aren’t enough.

      I recommend you check out Will’s Scalp Secrets guide for a more effective approach to hair regrowth.

      – Steph

  34. Should I wash my hair regularly if I apply peppermint oil+jojoba oil to my hair?Can I leave it on my scalp and wash after 2-3days? Also can I apply peo+jojiba oil to my scalp everday and wash after 2-3days?

    1. Hi Sruthi,

      Yes, it’s alright to leave it in for several days and wash it out on the second or third way.

      – Steph

  35. Hi Will,

    I recently purchased the grogenix scalp elixir. I am a 22 year old man and I bought the elixir for my hairline. I have a full head of thick hair but it is just my hairline that is somewhat receding. Can this scalp elixir help with possibly regrowing and fixing my hairline? I also use a 100% natural shampoo and conditioner that is suppose to help with stimulating hair growth. Once that tuns out I think I will get the shampoo from your website in hopes that it will help with my hairline.

    Hope to hear back from you soon!

    1. Hi G,

      Yes, the Elixir can be used on just the hairline, or all over the scalp.

      – Steph

  36. Is thinning and receding hairline in teenage years common? Can it be helped?

  37. Hi Will,
    Great post. Just one doubt. I already have a mixture of almond, olive and jojoba oil in a separate mix. Is it okay to add PEO to that mixture. If so what should be the proportion of these two in the mixture?

    1. Yes it sounds fine. Although I have never personally tried that mixture myself, so I don’t know for sure. The PEO should not be more than 5-10% concentration. Essential oils need to be diluted down by carrier oils. Aside from this I would definately recommend trying our Scalp Elixir formula. This is something we’ve been working on for a long time and is a proven formulation which gets results and is natural.

  38. This is great information. I’ve been using the peppermint the last couple of weeks. My question is, however, is this regrowth permanent, or if you stop using the peppermint does the hair that was regrown, fall out like the minoxidil/Rogaine?

    1. Hello Mar, any kind of topical treatment will not be permanent unless the underlying causes are fixed. Losing hair is an internal issue of body chemistry. Fixing this should be your priority. Once that is fixed, through nutrition and lifestyle changes for example then the regrowth your experience will be more permanent. If you don’t fix it then you’ll be fighting a losing battle. This is why for anyone who buys our Scalp Elixir we also strongly recommend fixing the internal issues at the same time to make the results better and longer lasting.
      Hope that helps.

  39. What is your opinion on using a high-frequency wand for hair regrowth along with oils, massages, diet, etc?

    1. Hi Cody, are you talking about an LLLT device? If so, yes I do think LLLT can help a small amount. It certainly won’t hurt. You might want to check out the Grogenix Laser Cap.

  40. If hair loss is an internal problem, can you give some examples on what things cause this? I eat very health and walk about five miles per day. I am struggling in my self image because I have always had nice hair now my temples and nape are almost none existing. Also, my hair appears to have not grown in about six or seven months and I haven’t changed anything. Help please.

  41. HI ,
    I have been mixing 1 drop of peppermint oil with a spoon of Sesame oil, is it effective?Its been 2 weeks and i am not able to find a positive result.

    1. Hi Alvin, honestly you’re not going to get positive results in two weeks. That’s completely unrealistic. You should also know that topical products aren’t really super effective. You will need to combine them with other treatments if you really want them to be effective.

  42. Hi,
    I’m 46 to and I’m losing my hair gradually and very slowly for about 10-15 years now.
    In the end, what’s the best method to do your treatment, cause I can see/read here lots of ideas.
    In thinking to mix the ingredients and make the shampoo described earlier in the article, but I’m also reading in the comments that someone wants to use peppermint oil every day and only wash the hair on the 3rd day. My question is, if you recommend diluting the peppermint oil, what’s the composition used for every day until wash, what do you add to be able to apply every day?
    I’ll be also using the dermaroller.
    Thanks in advance.

    1. I use a product called Ancient Minerals. I bought a 1 liter bottle off amazon and it has lasted me forever.

  43. Hi Will,
    I would like to try onle PEO with carrier oil twice a week. Will this work? or the frequency to be changed. Anyother suggestions please

    1. Hello Mohamed, I think it would be better than nothing, however if that is your only approach then I wouldn’t expect much of a good result. You’ll get limited results from a topical and even less so by using it just twice per week.

      1. Hi Will, Thanks for your quick response. Would you suggest magnesium oil+PEO spray everyday? Will that be helpful.

        1. You have to find the right regime for yourself. Some people prefer one day on, one day off. Also remember that there are other ingredients that will also be helpful additions to the mixture. And, I’m going to say it again now, don’t only focus on topical treatments! Topical treatments works by boosting blood flow to the follicles, but as you can probably imagine, that are much more powerful ways to increase blood flow throughout the scalp (massage being the primary method.)

  44. Thanks fo your complete information
    PEO is realy effective for hair growth and jojoba oil is very good carrier oil for it
    I’ve been used coconut oil , castor oil and jojoba oil as carrier oil for PEO and i recommend jojoba oil because it is more effective based on my experience

  45. I am VERY grateful for this website your created, Will. You are helping me to prevent and revert my MPB. I didnt want to use Finasteride or Minoxidil because of the side effects, so I kind of given up on my hair for a while until I found your website. And, to my surprise, the tips you give here really work! Thank you a lot man. Seriously. You are helping me so much!

    Please talk about Coconut Oil. It works very effectively but I dont see post around here about it.

    1. Hello Vitor, thanks for the support. I am glad that it’s going well for you. Honestly it’s not easy and most people give up on their natural regrowth journey so props to you for sticking with it and getting results. I totally agree about finasteride and minoxidil. Not worth it! We have an article on coconut oil here.

  46. With 1 tsp Jamaican Black Castor oil how much PEO need to add?
    I want to mix this for my beard growth.
    And can I mix PEO with Jamaican Black Castor oil + Almond oil + Eucalyptus oil + Rosemary oil together for beard and hair growth?

  47. Hi, i’m using Rogain. Can i use PEO with Rogain? And how about dermaroller with Rogain? Tks u so much.

  48. Hi will,
    I am 19 years old and have been experiencing hairloss on one side of my hairline since I was 17, the other side of my hairline is virtually perfect, I tried a mix of 100 ml magnesium oil and 10 ml peo spray tonight on my hairline and it got very red and very stingy, do I keep using this or would you recommend I shop before it damages it even more? Also would you have any advice as to why my hairline is only receding on one side? Many thanks

  49. Definitely will try and come back to comment on results. Some questions, are these methods also effective in restoring hairline lost? I’m hair lost isn’t TOO severe as I’m catching it in the early stages. But I do have a receding hairline and hair loss on the corners of my front scalp. In conjunction to using the stray and roller, what else do you recommend for maximum effectiveness

  50. Hello,
    I began using peppermint oil with just plain kitchen olive oil about four weeks ago. Before starting, I reviewed my medical history such as thyroid, and other medications (I do have a gluten allergy) to be sure that all lab work was within normal limits. I eat lots of veggies and fruit. I drink lots of water and exercise three to four times a week. Well within four weeks, I noticed a great change in the growth. I also changed my shampoo to Degrease with lemongrass and rosemary; and, I mixed the peppermint oil with my conditioner. I use the peppermint/olive oil every other day. I love the stimulating feeling of the peppermmint, and have seen excellent results. I have recommended it to family.

  51. Hi Will,

    I’m just wondering if you could explain this…

    If the hairs were shaved on the mice, you would expect some hair to regrow after a few weeks.

    Why then in the saline group is there no hair regrowth at all?

    Weeks 1 + 4 look basically the same.

    There should have been some regrowth during that period.


  52. HI Will!!

    Can I use this option in addition to using minoxidil and your scalp elixir?

    Would this be an overkill?

    I also have my own homemade hair oil, with essential oils added into it. Can I use this once or twice per week, instead of the other treatments?


    1. Hi Amar,

      You can use the minoxidil and the Scalp Elixir simultaneously (applying them at least 8 hours apart), but we don’t think it’s entirely necessary.

      If you aren’t currently on minoxidil, I would recommend you start with the Elixir alone. If you’re currently on minoxidil, I recommend you use the minoxidil in the morning and the Elixir at night. You can then slowly wean yourself from the minoxidil if you’d like, by slowly tapering how often you use it.



  53. Hi,
    I have been using rogain 5 % for years and in the last few years I have seen a lot more thinning in the front and center with receding hairline. Also been taking finesteride 1mg for few years but it does not seem to help much. I have hypothyroidism but the TSH levels are under control.Although they fluctuate at times. Not sure what else I could do to overcome this? I have tried many shampoos but does not help. Can using your caffeine shampoo along with rogain and finesteride help?Are there any updates/reviews/feedback from people who tried your natural oils and shampoo and havehad positive results.Is there any other suggestions you could give ?

  54. I can testify that this works! Been using it for two months now, and my hair has grown back in unbelievably. I was bald in the back, almost bald on top, and very thin in front. Now, the top is covered over again, the front is thickening up, and I see fine growth in the back. Can’t wait to get my first haircut in 25 years! I’m just astonished. Minoxidyl did not work for me and gave me irregular heartbeats. But I have no side effects from the peppermint and it smells great! The formula I use is jojoba oil, rosemary, lavender, and peppermint. I do have a dermal roller, so I might try that as well. But I can definitely tell you this worked for me!

      1. Will,
        You suggested that losing hair is an internal issue of body chemistry just the topical solutions and oils will not be enough what other things do you recommend.My TSH is under control and I try best to eat a healthy diet and exercise. Are there other things you can kindly suggest?

  55. Hi, it is difficult to find magnesium oil , can I use Homeopathic medicine Mag Phos 6x , coconut oil & peppermint oil together applied overnight. Kindly let me know.

  56. Hello,

    I am M/25 top almost bald, middle balding and front thinning and hair is turned almost brownish and lost its natural black color, i have an oily scalp but dry hair if that makes sense. I use a 0.5 derma roller once a week, just started 2 weeks ago, before derma-rolling i apply essential oil mix that i made that consists of 4 Tbsp Coconut oil, 4 Tbsp Castor oil, 7 drops of Peppermint, 5 Drops Rosemary, 5 Drops Lavender. I would like to know of how often should i apply the oil mixture in a week ? or should i only apply it while derma-rolling. Thank you in advance for your reply!
    Really hope this works

    1. Hi Wayne, I’d use it every day before bed. Probably avoid using it when dermarolling, as it could cause stinging. You need to be consistent and use it for at least 3 months for expecting to see any positive changes.

  57. Does peppermint oil initially shed hair, like minoxidil?. Thank you.

    1. Hi Khane,

      We cannot say for sure, as peppermint oil for hair growth has not been tested in the long term.

      I would say to use the product consistently for at least six months. If you notice a decrease in shedding and/or an increase in hair growth, then you can continue. But if nothing at that point then it’s okay to stop and consider other options.


  58. Hi

    I’ve read that you can mix peo with water in a spray bottle at a ratio of 5 drops to 4oz water just shake before spraying. I’ve tried mixing it with jojoba oil or mag and its messy so do you see anything wrong with my above approach?


    1. Hi Alan,

      As long as the oil is properly diluted, you can use oil or water to apply it.

      Just keep in mind that oil and water don’t mix. This is why we recommend another oil, such as castor or almond, to help deliver it more effectively. You may want to try other oils (such as coconut) to find one that you like.



  59. Can I add peppermint oil to the regimen I’m on now (scalp elixir + dermaroller)? Because the elixir doesn’t have peppermint oil in it, can I just add a certain amount of it to the elixir?

    1. Hi Marc,

      Yes, you can, though we do recommend you patch test it on the inside of your wrist to ensure you aren’t allergic/sensitive to the addition.

      You don’t need to add much, either. Just a few drops should do the trick.


  60. I would like to know if spraying peo and jojoba oil (vector oil) is still effective or is better using a dropper bottle?



    1. Hi Roberto,

      The answer to this will really come down to preference.

      If you have very short hair, or if you’re just spraying on the thinning/balding area, then the spray is probably sufficient. But the dropper can deliver the ingredients much more effectively to the area.


  61. Hello Will,
    Thanks for this great article.
    I would like to know if you experience hair shedding with peppermint essential oil + magnesium oil ?

    1. Hi Leo,

      As with any topical application, it’s possible to experience an initial shedding period. This should cease after 4 – 6 weeks, however.


  62. Hi Steph,

    I read that you recommend to use a combination of
    Magnesium oil (90%) Peppermint oil (6%) Rosemary oil (4%).
    On other sources I also read about Castor oil.
    Which one should be more effective? Castor or Magnesium oil?

    Another question I have is which needle size of a Derma roller would you recommend?
    I read that some recommend 0.30 and others say they using 1.5mm.

    And thanks so much for your al work and website.


  63. What do you think of the product “Trioxidil”? it is a more natural product than Minoxidil and without the side effects… But that’s what the laboratory (Foligain) says. As a matter of fact, I can’t find any study on it….

    I read that people used Minoxidil for the beard (there is a lot of information on it), others use peppermint and would be equivalent to 3% Minoxidil; from what I read on the internet

  64. Do you think it is wise to mix peppermint oil with saw palmetto soft gel capsules? I did a combination of argan oil+peppermint oil (%5 volume)+3 soft gel capsule of saw palmetto. Will it work? I couldn’t find anything about the topical application of saw palmetto extracts. (I mean the capsule ingridients, not the solution which contains alcohol.)

  65. Man, i come from a hot country and since i came to canada, my hair started thining year by year.
    First my skin was very dry and itchy, the water feels just wrong. I would get dry hair and dry skin after shower.
    At some point i would have eczema.
    Since two years my hair loss really accelerated, while i have no hair loss history at all in my family, mother side or father side. Im pretty sure the water quality and the lack of sun are the main reason.

    People way younger than me are already going bald, i’ve never seen that in hot countries.

  66. Hi

    1) Can I put 5 drops of peppermint oil per ounce of shampoo / conditioner in the shampoo or conditioner? So for example in a 13 ounce coconut oil conditioner bottle I’d put 65 drops of peppermint oil and then shake it very thoroughly and then apply it on my hair?


    2) mix 2-3 drops of peppermint essential oil with the dollop of coconut oil conditioner in my hand and then use the mix on my scalp

    Are both proper ways to use peppermint essential oil to promote hair growth or would those amounts be too much and cause hair loss?

  67. Hi Will,

    Since I have start using peppermint oil my hair shedding has increased. Is peppermint oil the reason?

  68. Hi,

    For a few years now I use “procapil” spray overnight as a topical hairloss solution, but I read a lot of good things about the mixture of Magnesium oil 90%, PEO 6% and rosemary oil 4% here, which is the reason I started to add this to my daily regime.

    Now for about 1,5/2 months I use the magn/PEO/rosemary mixture overnight and the procapil spray in the morning after showering.

    Unfortunately now for a few weeks I notice my hair is way more thinning (on top and also on the temples) than it was before and I can’t even style my hair anymore in the way I used to do it, which is really frustrating.

    Do you think this is normal? ofcourse I know it could be a shedding fase because I added the PEO mixture to my daily regime but I really start doubting that now after almost 2 months. How long should you advise to hold on to it and wait for improvement?

    Also, when and how much should you advise me to use my dermaroller, While I’m using 2 topical hair mixtures now daily. I mean, there should be a space of many hours between between dermarolling and the topical sprays right?

    I really hope you can give me some good advise about these questions!

    Your website and all the info on the website is really helpful, keep up the good work!

    A big thanks from the netherlands!
