Pumpkin Seed Oil for Hair Growth | A Scientific Review

Did you know that pumpkin seed oil may be able to to improve hair count and hair thickness in people with hair loss problems? This comes from the results of a 24-week research trial, which I’ll discuss in-depth below.

The intent of this article is to present all the relevant facts so that consumers can make an informed decision as to whether this claim has any merit and, if so, how to use it to achieve the desired results.

We will get there by answering the following questions:

  • What is pumpkin seed oil, and what does it do?
  • What does science have to say about it?
  • Are there side effects?
  • How do you use pumpkin seed oil?
  • What’s the bottom line?

But first, let’s take a quick look at what causes pattern hair loss (Androgenetic Alopecia (AGA)) in the first place.

An Introduction to Pattern Hair Loss

AGA is estimated to affect about 50 million men in the US (1). It generally begins with hair loss at the temples, continues on around the crown, and eventually leads to total baldness.

AGA is caused by a genetic predisposition (2). The principal androgen believed to be associated with it is dihydrotestosterone (DHT) (3).

It is thought that when DHT levels increase in hair follicles, the hair’s growth cycle is shortened and new hair growth is delayed (4). Over time, the hair follicles completely stop growing new hair.

The pharmaceutical treatment options for AGA are minoxidil and finasteride.

Minoxidil, commercially known as Rogaine, is a topical treatment that stimulates the hair follicles.

Finasteride, marketed as Propecia and Proscar, is a pill that works by binding to the enzyme – 5-alpha-reductase – that would otherwise convert free testosterone to DHT (5).

Both of these pharmaceutical options can be costly, and they also have potential adverse side effects.

The possibility that an inexpensive, natural substance like pumpkin seed could be an alternative remedy for AGA would certainly seem to justify all the fuss if it actually works.

What Is Pumpkin Seed Oil?

Pumpkin seed (cucurbita pepo) oil is obtained by expeller-pressing toasted, hulled pumpkin seeds. It is a rich source of antioxidants, essential fatty acids, minerals, and more (6. It is also a long-time foodie favorite for its nutty aroma and flavor.

Aside from being a delicious edible plant (it’s officially a fruit, by the way) and making a darned good pie, pumpkin is also known to have substantial medicinal properties including anti-inflammatory, and others (8, 9, 10).

Interesting fact: Pumpkin seed oil has been highly valued for its healing properties ever since it was first produced in Austria back in the seventeenth century.

As a matter of fact, in March 1773 Austrian Empress Maria Theresa issued a legal edict which stipulated:

“This healthy oil is unique and much too precious for using it in tasty meals and therefore should rather be used as a medicine. So it shall not be used as a culinary delicacy anymore but shall be collected and distributed only by the apothecaries.”

…and thus it was decreed.

Today, pumpkin seed oil is used to treat all sorts of issues and conditions, from prostate function problems to high cholesterol and more (11, 12, 13). It also tastes heavenly on a salad.

What Does Pumpkin Seed Oil Do For Hair?

There are a lot of health benefits attributed to pumpkin seed oil, most of which have nothing to do with hair loss. The following is a summary of the main health uses of pumpkin seed oil, including the conditions that it is used to treat.

Mineral Support

Pumpkins, like all plants that have a close relationship to the soil, are an excellent source of mineral nutrients.

Pumpkin seeds, extracts, and oil are all very good sources of the minerals phosphorus, magnesium (learn more about magnesium oil), manganese, and copper and good sources of the minerals zinc and iron.

Antioxidant Support

Pumpkin seeds have a broad diversity of antioxidants. For example, they contain a wide variety of forms of Vitamin E, two of which have only recently been discovered (15).

They also contain mineral antioxidants, (much like evening primrose oil) phenolic antioxidants, and lignans. This diverse mixture of antioxidants imbues pumpkin seeds with antioxidant-related properties that are not widely found in other foods.


Fatty acids isolated from pumpkin seed oil have been used in medicine for their anti-inflammatory properties, and include mainly linoleic, followed by oleic, palmitic, and stearic acid (16).

The people of Central America and India rub the oil extracted from the seeds of pumpkin on herpes sores, venereal sores, acne vulgaris and stubborn leg ulcers which refuse to heal.

Pumpkin leaves are also applied as a poultice on sprains and pulled ligaments.


Pumpkin seeds have antibacterial, antifungal, and antiviral properties as a result of their unique proteins (17).

Benign Prostatic Hyperplasia (BPH)

Pumpkin seed oil has been used to treat BPH successfully, based on its phytosterol, lignan, and zinc content, which is interestingly, what hair loss drug finasteride was originally intended to treat (18, 19).

Certain types of hair loss

As a proven antifungal and antibacterial agent, pumpkin seed oil can be helpful for maintaining a clean, healthy scalp and strong, healthy hair follicles (20).

In this way, it may be useful in treating hair loss caused by clogged hair follicles, dead skin build up, or some sort of scalp condition.

Male-pattern baldness

Pumpkin seed oil may be helpful in treating Androgenetic Alopecia (AGA), also known as male-pattern baldness (21).

What Does Science Have to Say About Pumpkin Seed Oil?

In other words, is pumpkin seed oil really an effective treatment for male-pattern baldness?

Befor and after results of using pumpkin seed oil on hair after 24 weeks

In 2014, Evidence-Based Complementary and Alternative Medicine published the results of a clinical research study that investigated the efficacy of Pumpkin Seed Oil (PSO) as a treatment for AGA (22).

This was the first randomized, double-blind, placebo-controlled trial to study this issue. The 24-week trial included 76 male subjects with mild to moderate AGA.

Half were given a daily supplement (which included PSO) in the form of a 400 mg capsule. The other half were given a placebo.

IMPORTANT! The supplement given to participants was Octa-Sabal Plus, which does contain pumpkin seed powder but also additional ingredients. These include Octacosanol (from vegetable powder), Gamma linolenic acid (from evening primrose), and Lycopene (from tomato powder). This means there’s no way to definitively say whether the PSO was the source of the study’s results, or if the other ingredients also played a role (which is quite likely).

The researchers used a process known as phototrichography to analyze hair changes, including hair counts and diameters.

Hair analysis was performed at the start of the trial to establish a baseline, after 12 weeks of treatment, and again after 24 weeks of treatment.

The results, shown in the two tables below, show that the PSO treatment group had significant increases in hair count over the placebo group.

The differences in hair thickness were negligible.

As a result of their study, the researchers were able to conclude that taking a PSO supplement for 24 weeks has a positive anabolic effect on hair growth in patients with mild to moderate AGA. They believed this could be due to the possible effects of 5-reductase inhibition.

Source. It’s clear from the diagram that the pumpkin seed oil had a positive effect on hair count compared to the placebo after 24 weeks. Difference in hair thickness compared to the placebo was negligible.

So, Can Pumpkin Seed Oil Treat Hair Loss?

As stated above, the supplement used in the trial contained PSO but it wasn’t the sole ingredient.

So, the real question becomes: CAN PSO treat hair loss by itself?

The answer is: We don’t know.

While it’s likely that pumpkin seed oil contributes various benefits, including anti-inflammatory and antimicrobial, there’s no way to tell exactly what effect it has on the hair growth cycle (24).

After all, the other ingredients founds in the PSO-containing supplement may have also contributed to hair growth.

These ingredients, including polyphenols (found in green tea) and gamma linolenic acid (sourced from evening primrose), have themselves been shown to possibly contribute to hair health and regrowth. As such, there’s no way to determine what percentage of the results were due to PSO, and what percentage was due to the other ingredients.

Does this mean you should avoid PSO, and disregard its positive health effects? No. 

But, you should know that much more research is necessary and there are likely better alternatives out there.

Are There Side Effects?

According to the University of Michigan Health System, pumpkin seed oil has no reported side effects.

However, it has been speculated that it might have a diuretic effect (26). For those of you taking lithium, taking a pumpkin seed oil-containing supplement might decrease how well the body gets rid of lithium.

This could increase how much lithium is in the body and result in serious side effects.

Finally, it is important to note that any natural remedy can cause an allergic reaction in some people, and this holds true for pumpkin and its many derivatives (i.e. oils, extract, etc.) as well.

Signs of an allergic reaction may include breathing problems, tightness in the chest or throat, chest pain, hives or rash, and itchy or swollen skin. Any of these reactions should be treated as a medical emergency.

Women who are pregnant or nursing should not take any supplement without consulting their doctor.

How Do You Use Pumpkin Seed Oil On Your Hair?

For use in maintaining a healthy scalp, pumpkin seed oil should be massaged into the scalp with some type of carrier oil such as olive oil and then left in overnight.

It has been suggested that this should be repeated at least twice a week for a minimum of two months before expecting to see results.

For treatment of AGA, pumpkin seed oil is ingested orally as a supplement. Pumpkin Seed oil (cucurbita pepo) supplements are widely available online, and at drug stores, grocery stores, nutrition specialty stores and the like. They are packaged as capsules or soft gel caps.

Dosages range from 500 to 1000 mg. Prices typically range from 15 cents to 35 cents per unit, depending of course on the dosage, brand, and quantity purchased.

Individuals deciding which supplement to buy should look for those containing pure, unrefined, organic pumpkin seed oil that has been expeller-pressed.

A recommended dosage for the particular treatment of AGA has not been defined.

How to Combine With Other Natural Treatments

While you can choose to apply PSO to the scalp, or take it as a daily supplement, there are treatments you can combine it with to boost its effectiveness.

Here are just a few that I highly recommend:


There are plenty of oils that can be combined with microneedling to improve results, but pumpkin seed oil is one of the better options.

Microneedling is a procedure that involves the use of tiny needles (28). They create micro wounds which, when they heal, help to promote collagen production and the proliferation of skin cells (29).

So, how can you use it?

You can use a dermaroller or a dermastamp, though a dermastamp is my recommendation.

Just apply the dermastamp to the areas of hair loss, and press down until the needles penetrate the scalp. Do this horizontally, and then vertically and finally diagonally.

So, where does the pumpkin seed oil come in?

You can apply it after your microneedling session, though I recommend waiting at least 8 hours before doing so. This will ensure there’s no irritation, but you’ll still receive the benefits.

Scalp Massage and Exercises

The dermaroller and dermastamp are great tools to use to increase blood circulation to the scalp. But you can also do so with your hands.

That’s right! Scalp massages and exercises are easy and gentle enough to do on a daily basis, but also incredibly effective at bringing more blood to the scap.

How effective?

In 2016, a study proved that 24 weeks of standardized scalp massage can increase hair thickness (30):


So, how can you see these same results for yourself?

How to Perform Scalp Massages

Using just your fingertips (and maybe even a bit of PSO), place your thumbs, index, and middle fingers on either side of your head (just above the ears). Place varying levels of pressure throughout the massage, begin to use circular motions.

You’ll start at the sides, and then move up to the crown, to the hairline and temples, and finally to the base of the scalp.

You can also trace back at any point during the massage, and even focus more exclusively on thinning areas.

This should take 10 – 15 minutes per day.

How to Perform Scalp Exercises

To further increase blood circulation, you can use your facial muscles to stretch and gently pull the skin of the scalp. Here’s a quick rundown of how:

  1. Lift your eyebrows as high as possible, and hold for 2 minutes. Return to resting position.
  2. Furrow your eyebrows as deep as possible, and hold for 2 minutes. Return to resting position.
  3. Lift your eyebrows as high as possible, and hold for 2 minutes. Then furrow your eyebrows as deep as possible, and hold for 2 minutes. FInally return to resting position.

You can also use your fingertips, and gently stretch the skin by pulling and pushing your fingers together.

Inversion Therapy

At this point, you may be wondering why increasing blood flow to the scalp is so important. And here’s the answer:

Blood contains oxygen and other nutrients vital to the hair, such as iron, zinc, and biotin. When the hair follicles are healthy (i.e. not in a state of miniaturization), blood flow is sufficient. However, miniaturization can ‘strangle’ the flow of blood from the arteries to the follicles and reduce both oxygen and vitamin delivery.

When you’re battling miniaturization and hair loss, proper blood flow can be the difference between further thinning and regrowth.

With that said, let me introduce just one more way you can improve circulation: inversion therapy.

This technique involves placing yourself in an upside-down position for a period of time each day. The blood will naturally flow to your scalp while in this position.

You can perform this with the help of specialized tools, or just by simply hanging upside down from a tree, or from a couch or chair.

This can be a bit unnerving at first, especially since you’ll be able to feel (in the form of increased warmth) and even ‘hear’ the blood rushing to your head. But if you can do it for at least five minutes per day, the results are well worth it.

What’s the Bottom Line?

There is promising scientific evidence to support the use of pumpkin seed oil supplements to treat mild to moderate AGA, also known as male-pattern baldness.

However, there has been only one trial, and much more research needs to be done to verify its results and identify a recommended dosage.

  1. This is very interesting research, and it’s exciting to see such a substantial increase in hair count. But why did the placebo hair count also go up?

    • Thank you Wendy, yes it’s very interesting. This is great point, there is clearly an increase in hair count for the placebo group. I can only imagine this is the power of the mind, the researchers didn’t seem to be able to provide a valuable explanation. I don’t think it invalidates the results though, if you’re worried about hair loss then taking pumpkin seed oil as a daily supplement is probably well worth it. Thanks, Will

  2. I’ve been eating 250 g raw pumpkin seed every day for the last 4 months and topically using it on scalp for the same period. I’m also taking a hair growth supplement, omega 3 and lot of almond along with green tea everyday. But the result is zero. I consulted 2 dermatologists and got blood tested. Everything was found normal…….Nobody can save hair……

    • Pumpkin seed oil isn’t a cure. Hair loss is a multifactorial problem and that’s why I created the Hair Equilibrium Framework. When you remove all the factors causing hair loss and boost and optimise all the factors that cause hair growth, that’s when you start to see amazing results. No one thing will work alone.

      • Did it have to do with inpurities and toxins? Bad fish oil is full of toxins, as our fish. But purified (distilled) and fish good fish oil from clean waters, like Nordic Naturals, or algae oils seem to be very beneficial from what I read. Refer to international fish oil standards certification and reports to check fish oils out. The Western diet has about a 17:1 Omega 6 to Omega 3 ratio – it’s 2:1 or 1:1 in the blue zones.

  3. Great article, I’ve been taking PSO for around 4 months, and obviously its hard to isolate the factors but I believe it is having a GOOD effect on my thin hair. Besides, the oil I use it tasty and very healthy, so why not add it to your diet if you’re worried about your hair?

    • I prefer the oil from a bottle because it seems more natural, the unrefined, cold pressed and crude PSO from Ol’Vita (pictured) is amazing stuff. The capsules may be more convenient, since I think you have to keep the Ol’Vita bottle refrigerated after you open it. The key is to take a high quality supplement consistently.

  4. Propecia made all of my hair grow back. The side effects were not worth it though, I lost all interest in women. No libido anymore but a full head of hair

    • Hi Jack, yes some of the side-effects of Propecia can be quite scary and definitely not worth it in my opinion. I would suggest that you slowly transition into more natural methods that I talk about here on the blog and in detail in my program Hair Equilibrium. I have personally found them to be just as effective as Propecia but instead of horrible side effects, the natural method gives amazing benefits such as glowing health, energy and wonderfully healthy hair. My philosophy is that hair loss is unnatural, and is a symptom of an imbalance in your body. Trying to fix the problem with a pharmaceutical can only have bigger, more disastrous long term consequences. Pumpkin seed oil is a good place to start swapping drugs for plant based alternatives.

  5. Hi there. Is your programme suitable for women? I’ve been experiencing progress hair thinning since my baby (20 months now) and not going back on dianette the, contraceptive pill, which I was on for 15 years and kept my hair and skin amazing. Since trying to go natural, my hair and skin is terrible. I’ve lost so much volume along the temples and bits won’t grow beyond a few inches. It’s gone from thick, strong and long to fine, wispy and broken. 🙁

  6. hi there william , can i consume pumpkin seeds instead of the pumpkin seed oil . if yes let me know about the daily dosage of it

    • Yes you can, I would recommend a handful per day. However, since there isn’t too much oil in the pumpkin seed you will overall consume a smaller amount. But a small amount is better than nothing.

  7. I have used both finastiride and dutastiride for hair loss, i have gained 20 pounds both times, lost libidio dht is important at some point in a man body for sure. Also minoxidil made my face swell, not worth it at all. I am using PSO in capsule form 1000mg per day. Lets see how things go.

    • Hi Frank, yes the side effects from those drugs can be devastating. Just remember when taking PSO that this is just the start. Don’t expect it to fix the problem of hair loss by itself. There is much more you can do as well.

      • What i notice now after 3 weeks of usage is that pumpkin seed oil combined with DIM and saw palmetto acts like a mild diuretic, this is a very positive effect compared to dutastiride and the water retention effect and weight gain. I am very happy ok admit i have been paying more attention to my diet, my training as always been on par 5-6 times per week in the gym, but i lost a bit of unwanted weight and my body is getting the beach body look, i love it, i hold on to less water. I was afraid that saw palmetto combined with pumpkin seed oil caps and green tea would have the same effect as dutastiride and i would gain all that unwanted weight and get bloated once again. 1 week after first starting dutastiride and minoxidil at 41 i asked my mother and she told me yes you look bloated tough it was normal aging sagging skin etc…… until i read all the side effects cause by this drug, also soft and no fun erection, low libido and more…… feeling bloated, dutastiride is for real but the side effects are even worst then finastiride since it blocks both forms of DHT. Minoxidiol will get the scalp dry and flacky something i have not been getting since using peppermint, magnesium melantonin and jojoba oil, my hair looks amazing like i put some gel in it but with some serious growth power.

  8. Hey Will,

    I bumped into your webpage today and I must say I really love your comitmment to improving health (let’s call it fitness) and countering hair loss. I do not know where this is going to take me, but I will follow some of your advice. I’ve been losing my hair since I was 17, and I’ve had dandruff since I was 10, and I’ve started suffering from a chronic inflammation of my facial skin and my scalp (the misterious auto(?)-immune/fungal desase called seborrhea) during puberty. During this time my scalp also got really oily for which even my hairdresser knew it resulted from a hormone imablance… That being said, I agree with you these things coincide in too many people so there has got to be a link and a possible cure…

    I just wanted to draw your attention to the first graph depicting the increase in the hair count. With those standard deviations, these graph cannot be statistically significant (I’m a life science researcher).

    Keep up the good work! 🙂

  9. Hi Will,

    Very interesting and informative article! I’d like to ask you what pumpkin seed oil supplement would you say is the most potent & pure? I’ve run into some forums with most folks saying that currently the brand: Planetary Herbals Full Spectrum Pumpkin Seed Oil in 1,000 mg dosage is top of the line. Please chime in and enlighten us! 🙂

  10. Hi Will,

    I don’t know why anybody wants to go looking for these rare and expensive oils for your hair when you have the long tested and proven for generations – Pure Virgin Coconut Oil.

    This is used by millions of people in the east, especially India in their daily hair grooming and as a conditioner.

    Almost all commercial hair conditioners are based on pure coconut oil. It prevents dandruff, a major cause of hair loss and helps in hair growth.

    I have been using it for decades and I still have a good crop of hair on my head.

    • Hi Shafeek,
      Fair point, some oils can be expensive and hard to find – pumpkin seed is one of those. But in this case, PSO can be taken orally and is proven to help regrow hair, whereas the same results don’t apply with coconut oil. However, I still highly recommend coconut oil for topical and oral usage and appreciate your comment about finding it useful keeping your own hair.

  11. Hi Will,
    I stumbled upon your site after researching products for hair growth. I’ve been thinning for a few years now. Thank God no bald spots though!! I’m struggling with trying to obtain thickness and shedding. When I notice strands of hair coming out, I notice a white bulb like on the end (I was told that was a good thing)?
    I’ve seen doctors and tried various hair products. None which seems to be making a difference. I’ve noticed my scalp gets extremely dryand flakey, and itchy that I wash it weekly. I read your article about magnesium oil and I’m interested in trying it. My question is have you heard anything about cayenne pepper for hair growth? Anything you can recommend for a scaley itchy scalp? Thanks

    • Don’t rely on PSO. Alone it will make almost no difference. You need to take a holistic approach and tackle the problem from many different angles. There is no ‘magic bullet’ Remember, PSO is believed to work by blocking DHT, and although this can help your hair, it’s more important to stop your hair follicles from being sensitive to DHT in the first place. That’s a whole different topic though.

        • Reduce inflammation from within the body. This basically comes down to diet and lifestyle changes. But inflammation basically makes them sensitive.

    • It’s probably better, because it’s a more natural form. However since the oil is a more concentrated form, it would be hard to eat enough pumpkin seeds everyday. But if you don’t mind chewing through a couple of handfuls then that would be a good option.

      • Pepitas (which are dehusked pumpkin seeds) are about 20% oil, so you would need to consume only 5 grams of pepitas to get your 1000mg dose of PSO. That’s about 25 seeds per day, which is less than half a teaspoon of pepitas (a bit more for pumpkin seeds with their husks still on).
        Much much cheaper than capsules of oil etc, which seems like unnecessary processing.
        Make sure you eat the raw ones, as cooking will degrade the product.

    • It’s up to you. However please be aware that you are blocking DHT so there is the possibility of side-effects. You will only get the benefits for as long as you keep taking it.

  12. I just imported the a bottle of pure pumpkin seed oil from Austria. its horribly expensive but let see if it works. Also I suggest to stop all the sexual activity for one year along with applying PSO to see great results. And abstain from any kind of masturbation.

    • Hi Schmidt, yes it is expensive. Remember to keep it in the fridge. Please let us know how it goes. I’d also recommend doing a few other things to see the best results. Consider scalp massages and exercises too.

      • Hello will

        Indian gooseberry is also solid for hair growth. But it’s hard to get it in the foreign country. I have been taking saw palmetto with fish oil, lycopene extract in placebo plus PSO and do rosemary oil and coconut oil massage twice in the week. And I will let you know in the six months. I might go for PRP treatment.

  13. I love your research and info! Thank you so much for all you do!

    I do want to add something which is probably a bit contoversial O_O…

    Concerning putting oils on your scalp: beware. I did this thinking it would help my condition (random, all of a sudden, Seborreic Dermatitis at age 36 for the first time ever and female hairloss, but all over, like I don’t have bald spots per se, but massive hair thinning, though mostly on the sides above my ears).

    So, turns out, malassezia (a fungus that lives naturally on your skin and can get out of hand and overgrow) feeds off of oils, fatty acids and esters in hair products, and also feeds off your sebum.

    It causes Pityrosforum Folliculitis (clogging of follicules with sebum), which in turn causes SD, and also feeds itself, the malassezia.

    I tried putting anti-fungal oils on my scalp, along with antifungal essential oils and it just got worse! Maaaassssssive hairloss that week, irritating and inflamed itchy scalp, and over all overwhelm.

    I had a scalp biopsy after that and turned out to be Malassezia overgrowth… I was feeding the fire putting oils on my head!!!

    The theory is that oils and esters with fatty acids that have a carbon chain length between C11-C24 are bad since they feed malassezia. That leaves only 2 types of oils that can be used, one of which is MCT oil (the REAL one that has C8-C10 and no additives).

    I have one called Brain Octane which is supposed to be pure C8, and tried that on my head as base for a home-made growth salve after a 3 week course of antifungals which helped A LOT to stop itching and to lessen hairloss, but guess what?? Hours later i had rinsed it off, i started feeling the itch again… and 3 days later, it was getting worse and worse again!

    Took an extra week of oral antifungals and back to normal. But I can’t keep doing that or I’ll ruin my liver!

    So either the Brain Octane is lying and it’s not pure C8, or the malassezia on my scalp, in my very humid tropical rainforest, mold incubator country in Central America, has mutated and now feeds off of lower carbon chain fatty acids…


    Any suggestions on a topical homemade lotion without fatty acids, esters and oils?

    Can witch hazel and or magnesium oil work as a base carrier for ecklonia caca powder? Supposedly they don’t feed Malassezia, but i’m nervous to try it out… trying to keep the few hairs i have left on my head…

    Also, for us people who have hair covering our spreadout hairloss areas (with abt soecific bald spots), how do you recomend we derma-roll?

    A year ago, I did try scalp therapies where plasma and vitamins where injected into my scalp and the pain for me was unbearable! I had severe scalp inflamation and couldn’t tolerate it.

    Thanks in advance!

    • Hello Erika, thanks for the long comment, that’s quite interesting.
      Regarding diffuse hair loss, yes I still recommend microneedling, although perhaps using a stamp rather than a roller would be better.

    • The seeds would be a very good option to add to your diet, so yes, I would certainly recommend them whether you can, or cannot get the oil. They obviously will contain the oil but at a much lower concentration.

  14. Hey will, I’ve been taking pumpkin seed for nearly a year and it’s definitely affected my sex drix (I’ve experimented on and off for some time to verify this). Perhaps this indicates it does have a finisteride effect. Is there any alternative to pumpkin seed oil you would recommend trying? I’m following the rest of the equallibrium program. So using the things you recommend topically. But this is a potentially a key ingredient? Thanks!

    • Hi Cam, I don’t think it is a key ingredient, however it does certainly seem to have some DHT blocking power, hence why it might be affecting your sex drive. If you feel uncomfortable with DHT blockers then it might be worthwhile focusing on other areas such as scalp massages more. For some of people sex drive might be more important than hair (although hopefully not a choice we have to make!)

    • Cam
      I dont think so pumpkinseed affects on sex drive. I have been taking it regularly since 10 months and i’m fine. But i have seen good result for my hair yet though.

  15. Hello,

    since 3 weeks I am eating only vegetables and fruits, and before 2 weeks got first PRP treatment, and next day saw alot of baby hair in my hair line, unel now they are still 1 mm and very thin! is there a way to make them dicker? of coure this will need nearly 6 Month I guess with good meal but how?`


  16. Hi Will,
    I have started to use the unrefined, cold pressed PSO from Ol’Vita that I found on Amazon, from one month now, so I can’t really tell of any result, but I am a bit concern about the daily dose to take.
    Do you know exactly how many teaspoon of PSO should be taken daily in order to avoid any side effects? Thanks


    • Hi Max,

      This is a bit difficult to answer.

      You’ll notice in the study that the men who received PSO did so in a capsule that also contained other ingredients. The total dosage was 400mg, but it’s hard to say just how much of it was PSO.

      Unfortunately, there aren’t any other studies which discuss dosage and side effects.

      We do know that pumpkin seed oil can be consumed safely, so the question remains “how much?”.

      I’d recommend you start with just 1 TBSP twice per day. You should continue on this for 4 weeks or so, and evaluate from there.

      Of course, if you notice any allergic reactions you should stop immediately.



  17. I started taking 1 tablespoon of extra virgin pumpkin seed oil along with 3 tablespoons no salt added Huntz tomatoe sauce for the lycopene. Do you feel this isa helpful combination in these ratios. Thanks.

  18. does it help with women hair loss , also is using a DHT blocker would help women too to reduce hair loss , especially for those who have PCOS ,does it do anything with dht levels and its effect on hair loss ??
