Using a dermaroller along the hairline

How To Use A Dermaroller For Hair Growth

In this article you’ll learn how to use a dermaroller to stimulate new hair growth. This method can help with diffuse thinning hair, or the typical M-shaped (widow’s peak style) receding hairline…

But you will need to know how to use this technique properly – or you risk damaging your hair further.

I’ve been experimenting with using dermarollers and dermastamps to help regrow my hair for over 3 years, and the method I use has changed quite a lot in that time. In this article I’ll share what worked and what didn’t.

NOTE: We do recommend you speak to your doctor about adding this tool to the treatment plan for your hair regrowth. You can have microneedling done by a licensed professional. Or you can do it yourself.

There’s also an FAQs section at the end if you have any questions about this.

Before we jump into the article though, I want to point out you can now get our Hairguard 1mm dermaroller for FREE >. It will be useful to have your own dermaroller to try out the steps I show you in this article. Never share dermarollers, it is possible to share blood-born diseases.

What is A Dermaroller?

A dermaroller is a simple device that is used to make tiny pin pricks in the skin. The pricks penetrate into the dermal layer, just deep enough to stimulate new cell production and boost circulation, but without causing damage and without causing pain (1). The process is also known as ‘microneedling’.

The dermaroller has been used as a beauty device for decades to renew the youthfulness of skin but stimulating collagen, reducing the appearance of wrinkles.

How Does the Dermaroller Help With Thinning Hair?

In a similar way that the dermaroller is used to stimulate collagen production on the facial skin, it can also be used to increase cell production and increase blood circulation around the scalp, which in turn will help with new hair growth (2).

The Science Behind Its Use

Microneedling has been studied for decades and, as such, there are studies which back its claims. Some of these even prove that the dermaroller and other similar tools — such as the dermastamp and dermapen — can be beneficial for your scalp. Don’t believe me? Let’s take a look!

Microneedles Can Stimulate Skin Cell Proliferation

In 2012, American researchers explored the role that microneedling had on skin cell proliferation (3). This is beneficial in the treatment of wounds, scars, hyperpigmentation, and even in growing hair.

In short, researchers determined that the procedure induces a three-step healing process. These steps are:

  1. Inflammation;
  2. Proliferation; and
  3. Remodeling (maturation).

These mimic the natural healing process that wounds undergo (4).

Typically, the remodeling phase can lead to scarring. So, why doesn’t microneedling cause the same?

According to a 2007 research study, scarring only occurs when the initial wound reaches a certain depth (5).

When using a designated tool, the needles do not penetrate this depth. They do, however, go just deep enough to initiate the healing process above which then triggers skin cell proliferation.

Are you still not convinced? Let’s look more closely at a 2014 study performed on patients with Alopecia Areata (AA) (6).

This small trial consisted of two patients – one male, and one female – presenting with patchy hair loss on the frontal and vertex of the scalp. The male had experienced this loss of hair for one year, while the female had experienced it for six months.

Each patient had been through various treatments, including injections of triamcinolone acetonide, topical steroid creams, and even minoxidil (5 percent). None of these were effective.

The patients were treated with a 10mg/ml concentration of triamcinolone acetonide twice per microneedling session. It was first applied before the session, and the second was applied after.

The sessions were performed using a dermaroller, and they occurred three times at three-week intervals. At the end of the study (nine weeks), the results were significant in both patients:

While this particular study was small and focused on patients with Alopecia Areata, it can help us to better understand microneedling’s role in hair growth.

Even better?

There are studies which show microneedling’s effectiveness in treatment Androgenetic Alopecia (AGA).

Microneedles Can Activate the Wnt/β-catenin Pathway

In recent years, scientists have linked the regulation of adult stem cells with hair follicle proliferation and maintenance (7). This is a process that’s largely regulated by the Wnt/β-catenin pathway.

This theory was put to the test in 2016, when researchers from South Korea studied the effects of repeated microneedle stimulation on mice (8).

The mice were split into groups of two, and various needle lengths were tested. These included 0.15mm, 0.25mm, 0.5mm, and 1.0mm. There were also two different cycle periods: 10 cycles (for the 0.15mm, 0.25mm, 0.5mm and 1.0mm groups), or 13 cycles (for an additional 0.5mm group).

The hair was shaved from the backs of all mice in the study, and magnified photographs (50x) were taken at days 7 and 14 after the first microneedling session. Regular photographs were also taken at 13 days and 17 days after the first session:

The results of a microneedling study as performed on mice

The researchers hypothesized that the growth was a result of the upregulation of various proteins, including Wnt3a, VEGF, and Wnt10b. This was proven when samples were taken from the mice.

And which groups had the best results?

Wnt3a, β-catenin, Wnt10b, and VEGF mRNA expression were all increased in the 5.0mm/10 cycles group when compared with control.

Microneedles Can Treat Thinning Caused by Androgenetic Alopecia

AGA is the most common type of alopecia in men, though it also effects women. The most common recommended treatments include minoxidil (for men and women) and finasteride (for men), but the desire for chemical-free treatments is growing.

Fortunately, there have been studies which show microneedling’s effects on patients with AGA.

The first study was performed in 2013, and it consisted of 100 patients with mild-to-moderate AGA (9). The participants were split into two groups. The first group received weekly microneedling treatment with twice daily application of minoxidil (5 percent), while the second group was given only minoxidil (5 percent).

Photographs were taken at baseline, and then all scalps were shaved to ensure equal length of hair shaft.

There were three parameters which researchers used to track efficacy:

  1. Change from baseline hair count at 12 weeks;
  2. Patient assessment of hair growth at 12 weeks; and
  3. Investigator assessment of hair growth at 12 weeks.

The results of this 12-week study were as such:

The mean hair count of patients in both groups improved. However, the improvement was more significant in the minoxidil + dermarolling group.

The investigator and patient self-assessment (which can be a lacking measurement technique) also showed a marked difference over the minoxidil-only group:

Microneedling vs control

And while the above study is promising, this isn’t the only study that was performed on patients with AGA.

In 2015, researchers from Mumbai studied the effects of microneedling on men with AGA who didn’t respond to conventional treatments (such as Rogaine and Propecia) (10). This study was small – only four patients – but it helps to shed further light on this procedure’s use in the treatment of pattern baldness.

All four patients were on finasteride and minoxidil 5 percent for anywhere from two to five years. There was no further loss of hair during this period, but there also wasn’t any growth.

Alongside their ongoing treatment, the patients were also subjected to microneedling sessions for six months.

The results were tracked using a standardized 7-point evaluation scale, along with patient evaluation. While these aren’t the most accurate way to gauge efficacy, they do offer a general look at progress.

At the end of the 6-month period, three of the patients expressed more than 75 percent satisfaction with the results, while the fourth patient expressed more than 50 percent satisfaction. In addition, all patients showed a +2 or +3 response on the 7-point evaluation scale.

A 2019 study further encourages the use of dermarolling as it reduces (or stops) hair loss, and participants could tell their hair was thicker and denser (11). Since there is little risk, if the tool is not shared between people, dermarolling should be considered as part of the tool box of dealing with hair loss.

While further studies need to be carried out, one thing is for sure – microneedling can play a role in boosting hair growth via various mechanisms.

How To Use The Dermaroller

You may choose to go to a licensed practitioner to try it for the first time. But you can do it yourself at home. While the dermaroller can be daunting, it’s actually quite easy to use.

On dry hair (to avoid tangling the device in wet hair strands), place the dermaroller at the edge of where you’d like to target (e.g. the hairline, or the outside of the crown).

Roll the device slowly over the area, first horizontally then vertically and then diagonally. You should apply enough pressure to penetrate the scalp and feel a slight prickling or tingling, but not enough to cause pain.

If there is hair in the area, be sure to move in the direction of the hair strands whenever possible to avoid pulling hairs out from the follicles.

You can continue the above technique on the various areas of thinning, or you can even perform it on your entire head.

Once you’re done, be sure to clean the roller using rubbing alcohol or an antibacterial soap. Then set it aside to let it dry, and place in its protective case or pouch until next time.

This technique can be practiced a minimum of once per week, but more than twice per week is likely too much.

Dermaroller vs. Dermastamp: Which Is Best?

The dermaroller is perhaps the most well-known microneedling tool, but it’s not the only one that exists. So, what other options do you have?

The dermastamp is one option. It’s a rectangular block on the end of a handle, and the block contains needles. Just as with the dermaroller, the stamp can also be used on the scalp and face.

What’s the difference?

Aside from the obvious structural differences, the dermastamp has a few benefits over the roller.

In particular, the stamp is much easier to manipulate when using it yourself. This is especially true for hard-to-reach areas, such as the sides and back of the head.

There is also less risk of damaging the surrounding hair follicles and removing healthy hair strands, which can occur if hair gets stuck in the roller.

Even better, you can purchase adjustable dermastamps (whereas such rollers do not exist). This means you can decrease and increase the needle length as necessary for best results.

Which do I recommend?

The dermastamp.

I’ve previously used (and recommended) the roller. And while I did have an overall positive experience, I found the dermastamp much easier to navigate and target particular areas of my scalp.

I’ve also found that it’s much easier to control pressure and needle length with the dermastamp, which is essential if you want to avoid permanent damage to the follicles.

Dermaroller FAQs

Which dermaroller should I choose?

There are lots of different styles, shapes and sizes of dermaroller, but they essentially all do the same thing. Get one with a round roller and high quality metal pins.

Whats is the best size of dermaroller?

The best size dermaroller I’ve found to be around 0.5mm, smaller than 0.25mm will have a reduced affect and larger than 1mm could cause too much damage. 0.5mm is the most common size so I would recommend that.

Can the skin get infected from the dermaroller?

It’s very important to properly wash the dermaroller before you use it again. If the pins aren’t washed properly then you increase the chances of infection.

Pour boiling water over the roller before using it, then allow it to cool before applying to your scalp.

Infection is very rare, but irritation can occur. Use your own judgment about whether the irritation is too bad to continue. See your doctor if you develop a rash or if the irritation doesn’t heal.

If you have an infection before using the dermaroller then wait until this clears up before continuing.

Will the dermaroller pull any hairs out?

The tiny pins of the dermaroller are not long enough to damage any existing follicles, however you should keep an eye out that it isn’t causing any undue damage to the scalp.

Typically you’ll be using the dermaroller on an area of scalp that is already bald, or along the hairline where there are less hairs.

If you’re using the dermaroller for diffuse hair loss than its important to make sure hair doesn’t get caught in the roller. You may have to do shorter strokes.

How do I clean the dermaroller?

 It’s important that you clean the dermaroller each time you use it. If the pins are dirty then you will increase your chances of getting an infection or irritating the skin.

Take an antibacterial wash and mix with water in a mug. Place the dermaroller inside the mug and leave for 1 minute and swish around. Never share a dermaroller. There is risk of sharing hepatitis, HIV, or other diseases.

Remove the dermaroller from the mug and rinse with boiling water.

Dry it, and place it back in its case, or a clean container.

How firmly do I press the dermaroller?

You should press it firmly enough so that it penetrates the skin down to the depth of the pin. This equates to a light pressure, similar to applying a roll-on deodorant. it shouldn’t feel uncomfortable but it may sting/tingle slightly.

You shouldn’t draw blood, and it shouldn’t leave any visible sign when looked at from 30cm away in my experience. I would recommend going lightly on the first round and gradually applying more pressure as you get more comfortable with using it.

What motion, direction and how many times should I apply the dermaroller?

You will want to get a good even covering of pin pricks which means using the roller in multiple directions across the scalp.

Can this method be used for Alopecia Areata?

Yes, this method has been successfully used by researchers to improve hair growth in male and female patients with alopecia areata (11).

Source. A female patient with Alopecia areata shows improved hair growth after 1 session with the dermaroller.


Microneedling is a promising treatment that could help you improve the overall health of your hair dramatically if you stick with the treatment. Some sources recommend only using a professional to use microneedling, and that those do it themselves have increased risk of skin damage or infection.

Be gentle. Doing it irregularly though probably won’t make much difference. It is meant to be one of the many tools you are using to address hair loss.

One every 7-10 days, lasting around 10 minutes each (depending on how much of your scalp you are using it on) is a regimen that many people have found to be successful.

Keep in mind though that microneedling should be used as part of an overall hair care regime. This alone is unlikely to make a true visible difference to your hairline.

Some people complain that this technique is uncomfortable and causes itching. This is not the most enjoyable thing to do to your scalp, however, the irritation soon subsides. For many people it’s a worthy discomfort for the benefits. Never share a dermaroller and if seeing a professional for microneedling, ensure they use sterile products and they are licensed in your state.

  1. Hello i a had read the whole site realy good stuff , I have good expiriance with dermaroller for years so some of my thoughts , I think 0.5 dermaroller is not enougt to trigger wounding process to make regrow , 0.5 is good for better apsorption of serum and stuff.

    I use 1.5 dermaroller once every 6 weeks you actualy need to bleed funny thing you will notice in time how spots that are reciding do not bleed much becouse or low circulation in that areas but with time and more use of dermaroller a lot more.

    I also use 0.5 2 times a week ,dermarollor is esencial in my opinion for wake up the sleeping folicle and triger them ,and dermaroler cant do any damage to skin or folicle so dont be afraid of little bleeding and some pain,massage is also great for everyday circulation

    • Interesting advice Goran, I think you may have a point with the larger size derma roller needed to fully facilitate the wounding process. I think it depends on your age and how many times you’ve used the roller before. Definitely something to take into consideration.

    • I’m going to buy the dermastamp from y’all. But I would like to know the routine. All you mentioned in the article was to use it on dry hair. But that’s it. I would like to know if it can be used before a shower or after when the hair is dry. I will be using some shampoo and conditioner that aids in thickening thin hair. Is it okay to do that or should I have one day where I don’t use the hair products and that’s when I use the dermatamp? I just want to know that’s it’s okay to use the dermastamp before a shower with hair product for thinning hair.

  2. I’ve been using minoxidil on my hairline for the past 10 years and am looking into dermarolling. Can I stop using the minoxidil once I start dermarolling?

    • They are better used together. However you should be aware that there are better natural alternatives to minoxidil, such as peppermint oil. I would recommend using that instead of minoxidil along with the dermaroller.

      • Hi I just received my derma roller 1mm. I have very thin hair and my scalp is very oily one every alternate days I wash my hair . Pls advise should I use the derma roller alone or after rolling do i need to apply any stuffs that prevent sebum?

        • Hi Karthik,

          You should be fine to use the dermaroller alone without applying anything afterware.

          You should start with the dermaroller once per week, as your scalp needs time to heal between sessions. It’s best not to use more than twice per week.



  3. Which derma roller do you personally use? I want to buy a good one but there seems to be so many warnings online.

  4. Hi Will and thanks for all your great info. Regarding dermaroller, could you recommend which ones to get, i understand needle size should be 0.5 but searching online some people say the ones with less needles are better and that there are fake ones which dont penetrate the skin.

  5. I am intending on using .25 before or after rogaine (yes I am working on switching to a natural option! I left another question about your elixir so I can switch). I am going to use 1mm ONCE a month to stimulate actual growth. You said that anything over 1mm is not a good choice, which is exactly what everyone else online says, but is 1mm applied less often OK? i know that everyone says 1.5mm should only be used by a doctor in a doctor’s office. I will follow this advice! What do you think about the .25 and the 1mm idea?

    I know people use the 1mm every week, because one study said to do this… but I am worried about doing too much damage.

    My other question is I am just starting this. I am not bald, but I can see more scalp since I had to discontinue rogaine for 6 weeks after a surgery. Will a roller still be helpful? Am I too late? does it actually promote regrowth or just sustain it. I am a little upset that I’ve reverted so much.

    I am also using 2 parts honey to one part onion. I heard onions are great for hair
    and it gets rid of that ‘itch’. it’s a nice mask I leave on for 15-30 minutes. I am doing it every day of the week before I shower.

    I was going to follow the website of the guy who is ‘steroids for men’ because he is well known, but I DONT use steroids, so I dont think it’s really applicable. He uses 1.5 every day, which seems a bit too much as far as I am concerned. even doctors say NO more than once a week.

    thanks for the help.

    I know I asked so many questions. My doctor doesnt know anything about this stuff!

    • Once per week is a good time frame to get started. You need enough time for the skin to heal in between sessions. However if you feel like your skin isn’t fully healing in the 7 days then it would be fine to extend the timeframe.

    • Hi Hue,

      You’d think that more is always better right? Well in the case of a dermaroller, that’s not necessarily the case.

      The size of the dermaroller will largely dictate how many needles it contains. If you’re hoping to target smaller areas of the scalp only (the temples, the hairline), then one with less needles may be all you need. But if you’re looking for one that can be used on the entire scalp, then a medium-sized one should do.

      I’d say choose one with a moderate number of needles dependent on the size. You don’t want to inflict too many wounds in one area (which a 1,200 needle dermaroller is likely to do), but you need enough needles to make an impact on the area.



  6. Hi Will
    How many times a week can i use the dermaroller 0.5 mm if i use magnesium oil with peppermint oil ?
    Can i use the oil the same day of the dermaroller?
    Thanks in advance

    • Hi Francesco,

      We recommend once per week, and we’d also suggest applying any topicals on the day that you use the roller.

      – Steph

  7. Hi all,

    Can anyone suggest best natural topical, ie oil based or component based application after dermarolling? Which blend of hair oils can I use for regression of the hairline?

    • I’d recommend our product GRO2 which contains natural oils and can be used in a regime with dermarolling.

      • Hi Will, sorry for the confusion, I thought you had mentioned earlier to not use the GRO2 product after dermarolling? Maybe I’m missing something? I ordered the derma stamp and the elixir from here, and am wondering as well what I am needing. New to this whole thing. Thanks

        • Hi Nathan, I mean immediately after microneedling. Basically because it will sting. Wait a few hours and it should be fine.

        • I know this is and older thread but can you clarify is if using a 0.5 once fortnightly (because that’s when collagen spikes at the 2 week mark) is harmful to then use 0.25mm bi weekly between that period? Or is it safe to use 0.5 & 0.25 somewhat in conjunction with each other?

  8. Hi Will,

    Thanks for all the info, very useful. Just to clarify, do I need to clean my scalp with the home made exfoliate peel each time before using the dermaroller? And after the dermaroller, can I use GRO2, will that work, or better to use the elixir based on jojoba oil, nettle leaf extract, etc. ? Thanks

    • Hi Kate, no you don’t need to use the exfoliate every time before the dermaroller. In fact you only need to exfoliate once per month, or less. It really depends on how quickly the plaque builds back up. After the dermaroller you shouldn’t use GRO2 (within a 12 hour period) for the simple reason that it will sting. You could use a topical mixture based on emu oil though.

  9. I am interested in getting my 18 year old son a derma stamp. He has some thinning due to either the recent 14 months on doxycycline, taking after his balding dad, or a little of both. He wants to fight hair loss naturally and we are loving the information we have found here! Going off doxy and following your diet tips has resulted in new hairs growing in within weeks, so a good sign. He plans to incorporate all your advice in a daily routine in order to keep the hair he has, including the essential oils, massages, and derma stamp. Onto my question: Someone at a hair growth product company advised against derma rolling or stamping if there is a history of acne. He made it sound like the micro needling would just cause an inflamed response and therefore even more problems. Any thoughts on this? My son’s scalp is healthy, no issues except the thinning of course. His acne is minimal and getting better with age and your alkaline foods suggestions– no surprise that what’s good for hair and scalp is good for skin. We know to sterilize the stamp, etc. Can he carefully try derma stamping, in your opinion?

    • Hi Terese,

      I would say to cautiously try out dermastamping. However, it may ease your mind to know that microneedling is actually used as a way to reduce the appearance of acne scars.

      – Steph

  10. Hello, I am a woman with shoulder length hair. Would you recommend derma roller or derma stamp to be most effective and not pull out my hair? Can derma roller be purchased from your website?

    • Hi Bianka, I would definitely recommend our new adjustable dermastamp. The length of the needles can be adjusted quickly and easily based on what size suits you best. The stamp is preferable to the roller because it won’t get caught up in the hair.

      • Thank you for all this wonderful information. What do you use to dilute the peppermint oil. Alone it can be very strong and burn.

  11. Hi Will,

    So, what happens if you’re someone like me who has been dermarolling for about a month now, but suspects that scalp calcification could be a factor? Other than some new, tiny hairs grow in, I haven’t noticed a whole lot of difference in regards to my hair quality (hair overall still very thin, brittle with constant split ends). It’s a little unusual that I my left front hairline is basically completely bald, while my right front hairline still has a bunch of hair (but still thin and some vellus hair areas.

    My routine right now consists of using 0.5mm once a week, then using 0.25mm every other day while applying Emu + Peppermint Essential Oil immediately after each rolling session. I just started spraying about 25 sprays of Magnesium Oil along with the Emu + Pepperminut as well, burns like crazy for like 5-10 minutes.

    I feel like if I have scalp calcification, the dermarolling isn’t going to work well in the long run because it’s squeezing the hair follicles off.


    • Hi Dave, are you doing daily scalp massages and exercises as well. These are actually much more powerful ways to reverse calcification and increase blood flow.

      • Hi Will,

        I was doing them, but then I started Dermarolling every other day and I find my scalp too sensitive for about 24 hours after rolling to be able to massage everyday. In regards to massage technique, I saw the “Choy” study on Detumescence Massage, claiming incredible results, but ZERO information on massage technique or Before and After photos, so I have been just massaging as firmly as I can, also squeezing and pinching everywhere.

        Not sure what else I should be doing as I feel Rolling + DT Massage is a lot, but maybe you can suggest something I’m missing?

      • It’s hard to do daily scalp massages in between dermarolling sessions because my scalp is pretty sensitive for about 24 hours afterward. Plus, there is basically no good information regarding proper massage technique (not even in that Choy study).

        • I found a Doctor who is a hair specialist/hair transplant surgeon after wasting about a year with my doctor and dermatologist. He said there are 3 things to do. Rogaine (or generic) foam for men 5% every day. Ketoconazole shampoo 3x a week. It’s an anti-fungal prescription and cleans out your hair follicles so they can function. And the laser cap, not wand, something like 3 alternating days a week for 1/2 hour. It fits under a hat, you can wear it on your commute or before bed etc. This doctor sold them and they cost a couple of thousand dollars. If you get one, find a doctor who can recommend a good one for you, don’t get one blindly off the internet. These are proven hair growth methods and each works on a different part of the hair growth cycle. But here’s the catch: They only work as long as you keep using them. If you discontinue use, all of the hair that was stimulated into growing will return to the way it was before. I asked him about using a needle roller in conjunction with Rogaine and he supported the idea. The only thing he said about cleaning the scalp, was to use a gentle shampoo as harsh shampoos can make sustained hair growth difficult. I don’t know how technically gentle it is, but I use Suave and have had a good result.

          • Hi,

            I have this female pattern baldness on forehead so my hair line is receding so my forehead is looking bigger too for same reasons and new hair is thinner than existing one. I tried topical solution treatment, ketoconazole etc etc. But it’s same. I use derma roller 1.0 for my face.

            What do you suggest for treating my hair problem. I have 0.5 and 1.5 needle size as well. ( My scalp has dandruff issue too).

  12. Hi Will! Thanks for the all tips you are sharing! I just started using dermaroller (0.25mm + 0.5mm) and this moment I have widow’s peak style receding hairline. In last three months I have had some positive results with using only coconut oil + rosemary&peppermint essential oil combo.

    Instead of mentioned oil mixture in the text do you suggest I continue using coconut oil + peppermint&rosemary combo after dermarolling? Im not the big fan of the emu oil because Im the vegetarian 😀 I guess it is better than nothing.

    • Hi Ville,

      Are you using the oil mixture immediately after dermarolling?

      Will recommends waiting at least 6 hours after dermarolling to apply the mixture you’ve mentioned. It can cause discomfort, and it may hinder healing.

      You can certainly continue with the coconut oil, or you can use magnesium oil.

      – Steph

  13. Hi Rob,
    Which is better- dermaroller or dermapen.
    What if I use 2 mm dermapen?
    Can it provide results or damage the hair follicles forever?

    • Hi Jimmy,

      The dermapen is better, as you can target its use.

      I would recommend starting with 1mm (or at least 1.5mm), as going too deep can damage the follicles.

      – Steph

  14. Hi guys!

    I’ve been Derma rolling for about 3 weeks now and I am starting to see a little bit of results on the front of my hairline, but what does it mean when the front of your hairline gets flaky and dry?

    Please let me know.

    Thank you!

  15. Hi Will,
    I just purchased a 0.5 dermaroller and would like to try this in conjunction with an essential oil treatment on my scalp but I have a few questions. How often do I use the dermaroller weekly? Can I use the essential oils at different time than dermaroller to avoid any negative reactions? Also how often do I apply essential oil treatment? Please help I need guidance. Thanks.

    • Hi Frank, we do recommend the 1mm roller, however to get started the 0.5mm will be fine. Aim for once weekly but assess your skin and how well it heals each time. Do not apply the oils after using the roller as this will sting. Leave it 24 hours before using a topical with essential oils. Thanks

  16. I didn’t think I had any noticeable dandruff, but yesterday I used a boar bristle brush on my head and it started flaking like crazy. I didn’t notice any damage to my scalp or anything but the brush was filled with flakes. So I’m wondering, I read somewhere that I shouldn’t use a boar brush or scalp exfoliation with a flaky scalp. Ive also completed two homemade scalp exfoliations but didn’t seem to see any results. I want to start dermarolling but should I make sure the flaking stops First? Will I still see results from dermarolling and applying the scalp mixture even with a flaky scalp?

    • Hello Jake, there is always going to be some flaking if you use bristle brush against the scalp. It’s basically inevitable. I would start dermarolling even if you have the flaking going on and in the mean time work towards sorting the dandruff problem by optimising your diet and other things that help dandruff.

  17. Hello.I use the dermastamp 0,75 one time per week cause i am a begginer.After needling my scalp i notice that my skin exhibits small sweat drops equal to when skin sweats under normal conditions.It looks like sweat which doesnt make any sence to me but could it be puss from skin irritation??However i feel good with no pain and irritations.

    • Hi Manos,

      I’ve never heard of that occurring. Very interesting!

      Puss has a very distinct look, so I’d think you’d know if it was puss. But I’d say to just keep an eye on it. If you begin to notice swelling / irritation, then stop using the dermaroller. You may also want to consult with a dermatologist to ensure that dermarolling is safe in your case.



  18. Is it a bad idea to use the dermaroller across areas of the scalp with significant hair coverage? I have areas on the edge of my hairline that experienced hair loss due to folliculitis. I’ve used a peppermint oil solution to eradicate any scalp issues and I think it’s helped to regrow new hairs in the area but I want to maximise my hair growth with a derma roller but worried it might be bad going over these areas of my hairline that aren’t actually completely bald as it’s just not as thick as the rest of my head.

    • Hi Tyler,

      It’s true that going over areas of dense hair growth with a dermaroller can pull the hairs from the follicles. But you’re also correct that it can be beneficial and increase the density of the present hair.

      To avoid pulling hairs out, I’d recommend that you do those areas very slowly. You should also only do so on a dry scalp (as wet hair can become more easily tangled in the needles).

      You may also find switching from a dermaroller to a dermastamp is more effective. The stamp is less likely to damage existing hairs, and it’s easier to control.



  19. Hey Will,
    how long does it take to see results?
    Is it okay to use dermaroller for a seventeen year old boy who is suffering from diffused pattern hairloss?

    • It varies for everyone, but I would give it at least 1-2 months. ‘Diffused pattern’ what exactly do you mean by that? Diffuse loss in men is not generally associated with androgenetic alopecia.

  20. Hi will,

    Is it better to use a dermapen instead of a dermaroller or dermastamp? I know it is more expensive but i have all 3 at home which should i use?

    A dermapen is an electric version and all prp treatments use it over the others. What is your take?

    • Hi Josh, I have never tried a dermapen, so for me the dermastamp is the best. I use our own Grogenix adjustable dermastamp so I can perfectly control that size of the needles.

  21. Hi iam Amal
    1. Will it be effective if I shave my hair and use dermaroller
    2. Which dermaroller should I use after I shave my hair

    • Hello Amal, yes it might be more effective if you shave your hair, at least it will be easier to use the roller. However it’s not necassary if you don’t want to.

  22. Hi Will,

    So I’ve read numerous articles on your website and all over the internet all about to regrowing lost hair due to MPB (currently sitting at around Norwood 3-4, worse at the left, front portion of my scalp which is basically bald aside from Vellus hairs). There oddly seems to be a lot more hair on the right side hairline which I find odd, but hair still thinning.

    My current routine of a good 3+ months so far has been:

    -Dermarolling using a 0.5mm roller, once per week, followed by application of Emu Oil + Peppermint and Rosemary Essential Oil immediately afterward.

    -Dermarolling using a 0.25mm roller every other day following the 0.5mm rolling session after a week of rest from the 0.5mm session, followed by the same above Oils.

    -Occasional scalp massage (still have no clue of proper technique, and that Choy study on “Detumescence Therapy” doesn’t outline massage technique at all).

    -Hair wash and condition morning after every dermarolling session using Morocco Method shampoos (all natural).

    Despite doing all this, I can honestly say I have seen very little difference in the 3+ months I have been following this routine. I eat a very healthy diet (Paleo Diet) and I exercise frequently. I’m in my early 30s, but my hair has been gradually thinning and disappearing for the past 6-8 years or so. All I can ask is – what am I missing? All the before and after reports for people who have dermarolled consistently for 12+ weeks have posted DRAMATIC results, going from essentially a lot balder than myself, to having a full head of thick, dense hair, so I can’t fathom a guess as to what I might be missing.

    If you can offer any advice, I am willing to hear whatever you suggest.

    Thanks in advance!

  23. Hi there. I’ve been dermarolling and applying peppermint oil along with rosemary oil ( with a carrier oil) once a week for 4 weeks now. I feel like I’m still having lots of shedding. Is this fairly normal in the early stages of dermarolling?

    • Hi Sunny,

      Some people do experience a shedding period to start off with as your hair cycles through from telogen phase to anagen phase.

      This should cease after a couple of weeks.

      – Steph

  24. Hi will,
    I have read all your advice and for parts of my scalp it has worked. Now for my receeding hairline i am planning to use a derma-roller. The question i have is to i have to do an acid peel on my hairline which is mostly skin. Also, could i use only peppermint oil after dermarolling as i am confused with using lots of oil mixtures so i am wondering if using only peppermint oil is okay.
    A response will be highly appreciated.

    • A peel is not always necessary. I would recommend more than peppermint oil as a topical, however don’t use it straight after rolling. Wait at least 6 hours or it will sting a lot.

  25. Hi, I have bought all Grogenix products and they are great!
    One thing which is missing is a mix that can be applied after the micro-needling sessions – I understand the positive effect of micro-needling is maximised when the proper mix is applied straight afterwards, but the Elixir cannot be used due to stinging. Are you planning on releasing such a product?

    • Hello Ivan, thanks for your support. Glad you like the Grogenix products, we are working to develop them even further. That’s a great point! Microneedling is certainly maximised when applying the right mixture after and the Scalp Elixir is NOT the right product for this as it causes stinging. We are currently working to develop such a product but I can’t say with certainty when it will be ready as we need to test it thoroughly for long term efficacy before releasing it. Hopefully it won’t be too long.

  26. Hi, I am using DermaRoller 0.5mm once per week from last 2 week and applying argan oil after 12 hours is it okay ?

  27. Hi. I had a FUE hair transplant 1 year ago on the frontline. My previous hair were still there at that time but were not showing any proper growth. They have reduced a lot by now.
    I want to ask that can i use dermaroller only on that area of the scalp where transplant is not being done or can i roll it even on the transplanted area?
    Thank you

    • Hello Muhammad, although you should talk to your doctor first, I can’t for-see any problems microneedling the transplanted area of your hair. And after a year I would think that it would also help to micro-needle the transplanted area too. You should confirm this with your surgeon though.

  28. Hi Will,
    Great info! Thank you so much for pioneering this process. It’s a lot of info to digest and I find I’m getting lost in all of it. Curious if you would be open to a FaceTime consult to review the protocol to make sure I get all of this correct. Possible you could email me to discuss some options? I need to put an end to the constant late night scrolling and searching for my hair loss solution ??

    • Hi Chris, thanks for your kind words. Currently we can’t offer one-on-one help because there just isn’t enough time for us and our team right now. But this is actually something we’d like to be able to do in the future, since it looks like it would be helpful for lots of people and really help to accelerate results. Feel free to subscribe to our email group or join the Facebook group and we’ll let you know as soon as that’s up and running.

  29. Hello Will!
    Can I just apply coconut oil +peppermint oil after the dermaroller use(I would apply it after 8 hours)? I’ve not tried it yet as I fear that the peppermint essential (being so strong) might burn/ittitate my scalp (even after 8hrs gap?). Please let me know. And I’m planning of not applying anything after my dermaroller session (for 8hrs). Can this be done?

  30. Hi,
    I understand from one of your responses that Grogenix still does not have a product to apply right after microneedling. In its place what topical mixture would you recommend to be used right after microneedling?

    • Hi Peter, yes that’s right. We don’t recommend to apply the Scalp Elixir after microneedling. We are working on a product that will be used exclusively after though. One of the ingredients will be a IGF growth factor serum. You could start there?

  31. Hi Will,
    Which oil is better? Rosemary oil or Peppermint oil? And can I mix BOTH these with a carrier oil and apply? And if so, in what proportions should I mix the essential oil(s)?

    • Hello Mahendra, don’t apply these oils right after using the roller because that will stong a lot. There are serums you can use after but they don’t contain essential oils.

  32. HI team, just want to confirm if this method is ok:

    1) I slightly dampen the hairline and apply light tea tree oil to clean the area
    2) I use the dermstamp once a week around the receding parts of the hairline only (approximately 5 minutes)
    3) I apply grogenix scalp elixir straight after.

    Appreciate your feedback.

    • Hi Joe, no do not apply the Scalp Elixir straight after using the dermaroller. This will sting a lot. You should wait at least 8 hours to apply a topical after microneedling.

  33. Hi guys

    I forgot to ask. If I just have a receding hairline, can I just apply the dermastamp to this area or is it advised to cover the whole scalp?


    • Hi Joe, that’s a good question. I would say that in general it’s better to go over the whole scalp. However, if you have limited time then going over just the area which is thinning/receding is also very good and beneficial. To give you more of an idea, we always recommend scalp massages all over, rather than in just the specific area of hair loss.

    • Hi Matt, for a dermaroller I choose the 1mm size. You can also consider getting the adjustable dermastamp so you can adjust the needle size to suit each part of your scalp. Since the scalp has varying thickness it can be useful to adjust the size sometimes.

  34. Hello there. I’ve just started Dermastamp. I use a tip close to 1 mm. I plan to use it twice a week. Dermaroller is a mixture of 15 oils with the following link (Pine Oil, Snake Oil, Argan Oil, Black Seed Oil, Sweet Almond Oil, Pine Terebentin, Olive, Wheat, Walnut, Clove, Entele, Sesame, Baobab, Nettle, Tea Tree, Aloe Vera, Daphne, Jojoba and 3-fold liquefied keratin supplement)

    I plan to use the organic oil cure and mint oil alternately. Can I use these oils now? If I use it immediately, would it clog the hair follicles? Or should it take some time? I will also use peppermint oil. I should use the peppermint oil immediately after dermaroller or after a while.

    How long should mint oil stay in my hair? Do I need to wash my hair after mint oil? I would ask you to provide information. Thanks.

  35. I am 35 now, and I have a large vein (you can’t really see it), but it makes a Y shape right at my hairline, and I notice that although my hair is starting to thin on top, the hair directly above those two veins where it splits to the Y shape is noticeably LESS thin.

    This tells me that nutrient delivery and blood circulation to your scalp is easily one of the most important things.

    I’m doing a bit of research now, but I am centering on tactics that aid and promote blood flow because I think long-term, that is the most important thing towards keeping your hair youth-like.

    I don’t see a lot of talk about circulation being the most important thing, but looking at the hair on top of that Y-shaped vein, it’s pretty obvious to me this is the most important. I am willing to bet that a dermaroller and some scalp massage is better than any topical treatment or hormonal treatment. I think anyone will see more change by focusing on this.

    I just leave this comment for future researchers. Go to the gym, eat well, and focus on blood circulation and nutrient delivery to your scalp.

    • Hi Adam, thank you for your comment. I think this is very interesting and insightful. I agree that hair health is all about blood flow. From the research it’s clear that subcutaneous oxygen is very important for hair growth. Scalp tension also cooincides directly with areas of hair loss. It all leads back to blood flow. This is why scalp massages + using the growband is so effective.

      We’ve found by the way that using the Growband for ten minutes each day increases the temperature of the scalp significantly, clearly showing an increase in blood flow.

      Agian, thank for your comment and let us know your progress.

  36. I have the hairmax wand I use 3 days a week. I know to wait at least 4 hours after the elixir to use the wand. My question is…if I use the dermastamp can I still use the wand? If so, when in conjunction with the wand do I dermastamp?

  37. Thanks for this article after reading this I know very well about a Dermaroller, this is very helpful for those who want to regrowth hair naturally and you covered many topics related to Dermaroller it is very helpful.

  38. You repeatedly mentioned that peppermint is a more natural more potent alternative to minoxidil but my question is how exactly do I use it , what if the ration of the oil to a carrier oil ? How many times a day?a week ? And can I use it with water as opposed to cattier oil because I have an oily scalp and oil seems to accelerate hair fall ?

  39. Hi Will,
    I am Apoorva.

    I want to get one thing clarified before using this as this is my first time.I watched what a dermaroller does to a person’s skin in YouTube.They tell that due to miniature punctures in the skin there will be collagen production skin will regrow like after we get hurt skin will again form over it (This is on face I am talking about).Now if we use dermaroller for Hair how is it different and grow hair instead of regrowing skin?This is my main concern before starting because I am afraid that what ever hair is also present that will go and collagen will happen.

    This is the first time I want use a dermaroller.But I have dandruff.So is it still okay for me to do dermarolling?And what is the procedure?Like as this is the first time should I take 0.5 dermaroller and do dermarolling immediately after washing my hair and apply coconut oil or apply coconut oil and do dermarolling and wash my hair(after how many hours can we wash our hair).Is only applying coconut oil okay will it show nice effect.

    And can I buy or get a free dermaroller from this website if I am from India.As there is no option of India in country option.

    I am asking all these questions at once as I want to get clarity and start using it.

    Hope you will give me an answer.

    Thanks in advance

    • Hi Aproova,

      Thanks for your questions!

      You’re correct that dermarolling will increase collagen production. But the skin that regenerates will include hair follicles so that new hairs can grow. The collagen will also enable the present hair follicles to heal.

      If you have dandruff, it’s best to treat it first before you dermaroll. This article on dandruff can help:

      As for a schedule, we recommend you start at either 0.5mm or 1mm and perform the procedure once per week. We recommend you do it on a dry scalp, and applying coconut oil afterwards is fine.

      Unfortunately, we do not ship to India. You can likely find one at a local beauty store, or even Amazon.



  40. I am 22 and have thinning of the crown, I begun using rogaine a week ago, should I stop and just use peppermint oil and dermaroller?

    • Hi Jacob, I’m not a doctor so I can’t offer this kind of advice. There isn’t clear evidence peppermint is more effective, but the research does seem clear that a dermaroller will improve the effectiveness of a topical product. But also remember, no topical product is super effective, you’ll need to incorporate additional steps into your hair care regimen to see good results in my experience.

  41. I just got my roller 1.5m and also .25m for daily use. But im wondering if I switch to 1.0m I can run with that weekly instead of 1.5m every 4-6 weeks?

    So for now since I used the 1.5m I need to wait how long before I can start using .25m daily? And since I used 1.5m how long until I can switch over to the 1.0m weekly?

    I did not see much blood using the 1.5m and if I did it was just a bit on the front on my hairline, but nothing terrible. Scalp was red and right now it itches. I use minoxidil for now and was told I need to wait 24 hours? Some say they use it right after treatment.

    hope you can sort me out here. Was I suppose to bleed like crazy with the 1.5m? And if so I guess I did not press hard enough.

    • Hi Joshua,

      You should never “bleed like crazy” when using the dermaroller. You may draw blood every now and again, but it shouldn’t be an every time occurrence.

      I’d recommend you switch to the 1.0m dermaroller on a weekly basis. I’d also recommend you stop with the daily dermarolling, at least for a few weeks.

      Your scalp needs time between sessions to heal. This will yield the greatest results.

      As for when to use the dermaroller after minoxidil, we’d recommend you wait at least 12 hours. Though, you can always skip minoxidil on the one day per week that you dermaroll.



  42. Hi Guys,

    I finally started using your derma stamp this last Sunday. Today, Tuesday, two days after, as I was brushing my hair, I experienced abnormal shedding, especially on the sides. I counted 50 hairs coming out. On a normal day it’s 5. Could this be attributed to the Derma Stamp session I’ve just had? If so, what do you recommend? FYI, since June, I’ve also used your laser helmet every other day and done scalp massages every night. This last Sunday I only did microneedling, though. Please, advise. Thank you and Best!

    • Hi Carlo,

      It’s absolutely normal to experience an increase in shedding for the first few weeks of dermastamping. It’s certainly a shock, though!

      The shedding should decrease after your next few sessions.

      I hope this helps to ease your mind!


  43. I’ve been using a 0.5mm Dermaroller once a day and then a topical solution afterwards for years now after receiving this advice from a “Hairloss Specialist”. But i feel like once a day might be too much for Dermarollering based on what I’ve read and how long it takes for the scalp to heal. Some people even recommend gaps as long as every 3 months. What would you suggest for 0.5mm? Is there any solid research testing the best size needles and space between treatments? Ps love your YouTube channel, and just ordered your Scalp Elixir to get away from Minoxidil.

  44. I’ve just started using the 1mm Derma Roller I bought from your website and its only been a month. No change so far but I’m also not using any chemicals and I am shampooing less often than I have. e.g once or twice a week.

    I take it I can just use the derma roller on its own? I’m a bit worried about the side effects of using Minoxidil!
