Various different vitamins spread across a table

The Best Vitamins That Can Block DHT

Before we get in to the best vitamins that block DHT, you should probably be aware that high levels of DHT are not the only cause of hair loss.

In fact, there is something even more important to preventing hair loss, and that’s DHT sensitivity.

See, people who suffer from hair loss don’t have abnormally high levels of DHT, it’s just their hair follicles (and the dermal papilla) are more sensitive to DHT than those who don’t suffer from it.

For that reason, I’ve included in this list all the vitamins that decrease DHT sensitivity, as well as blocking it.

Some vitamins work directly, some promote overall good health that can then lead to lower DHT sensitivity, but both will be discussed here.

I’ve also included a few minerals to the list that can help block DHT as well.

If you prefer watching rather than reading then check out our video below:

Niacin – Vitamin B3

Fish, avocado and peas are foods that contain high amounts of niacin

Niacin (vitamin B3) is an essential human nutrient, and one which can be found in high quantities in a variety of foods. Its main claim to fame when it comes to fighting hair loss is its ability to increase blood circulation in the scalp.

There are many hair loss causes, but a major factor in your hair’s health is its access to a continuous blood flow.

When blood flow is restricted, it can lead to brittle hair which easily breaks. This can also compound the effects of DHT, as no blood flow means there’s no way for chemicals (including DHT) to be removed from the follicle).

And did you know that men with early Male-Pattern Baldness (MPB) had subcutaneous blood flow that was 2.6 times less than their healthy counterparts?

All of this to say, blood flow is critical to hair health and niacin can help. How?

A common side effect of niacin supplementation is flushing. This occurs because niacin is known to dilate the blood vessels, and this increases blood flow to the face. Niacin can even reduce the viscosity of blood, so it flows more easily through your body!

Other benefits of niacin supplementation include anti-inflammatory effects (great for reversing hair follicle miniaturization) and increased keratin synthesis.

So, how can you get more niacin into your diet? Include these foods:

You can also take a daily niacin supplement, but it’s best to speak with your doctor before doing so.

Biotin – Vitamin B7

Biotin, also known as vitamin B7, plays a major role in the metabolism of food. It’s also been shown to be a major component of the hair, skin, and nails, as biotin functions as a protein synthesizer. As keratin is the protein found within the mentioned three structures, it makes sense that the presence of biotin is important.

Are you still unsure of biotin’s role in hair health? Let’s take a look at the effects of biotin deficiency.

Biotin is found in abundance in the foods we eat, and it can even be produced by healthy guy flora. And even with biotin deficiency being rare, researchers have been able to study its effects.

To name just a few of the symptoms of biotin deficiency, they are:

  • Seizures;
  • Hypotonia;
  • Ataxia;
  • Nail weakness;
  • Dermatitis; and
  • Hair loss

So, how can you be sure you’re getting an appropriate amount of biotin in your diet? Include foods such as:

  • Beef liver;
  • Egg, whole;
  • Salmon, pink;
  • Pork chop;
  • Sunflower seeds;
  • Sweet potato; and
  • Almonds

You can even find biotin in a variety of multivitamins, especially those aimed at hair, nail, and skin health.

Zinc and Selenium

Zinc and selenium are two trace elements that are often discussed together, and for good reason. They’re often found together in many cosmetic formulations (such as face wash), and both play a critical role in the human body.

As antioxidants, zinc and selenium are vital in the fight against free radicals. They protect the skin (and other organs) from aging, and keep many cellular processes functioning properly as a result.

Interestingly, both zinc and selenium also play a role in the keratinization process.

As outlined above, keratin is a protein. In fact, it’s the main protein found within hair.

However, proteins aren’t just naturally present within the body. Instead, they must be synthesized. This is done through various processes, and protein synthesizers such as zinc and selenium help to make this happen.

It’s not actually necessary to take these vitamins daily, as an overabundance of zinc can lead to thinning and hair loss. Though, you should speak with your doctor about your nutrient levels, and they can prescribe a course of action if it’s found that you have a zinc or selenium deficiency.

A better course of action is to ingest foods rich in these vitamins. These include:

  • Oysters
  • Red meats
  • Almonds
  • Pumpkin seeds
  • Wheat germ
  • Egg yolks
  • Soy products

You can easily add many of these ingredients to a delicious smoothie, or make a bone broth that will satisfy your hunger and nutritional needs.


As a major regulator of biochemical processes within the body, magnesium is a crucial nutrient. It’s also been shown to play an important role in hair health and growth.

Magnesium is sometimes linked to calcium, and here’s why: magnesium is often used to ‘regulate’ calcium’s presence.

But calcium is good for you, so why would you want to limit it?

This is because too much free calcium within the body can lead to calcium deposits. In people with hair loss, this can even lead to calcification of the scalp. If not treated, this can lead to fibrosis of the tissues, which results in irreversible baldness.

Calcium is found in many foods, and you may even be getting an oversupply of it from your own water supply!

This is why I recommend applying magnesium oil to your scalp daily, whether by itself or mixed with essential oils (such as peppermint and rosemary).

You can even take a magnesium supplement if you’re deficient, though it doesn’t need to be taken daily. You should speak with your doctor if you suspect deficiency, as well as to find the best treatment plan for you.

Vitamin E

Antioxidants play a vital role within the body by ridding it of free radicals. These are molecules which essentially break down the body over time, as they steal electrons from surrounding molecules. Perhaps one of the best known antioxidants is Vitamin E, and here’s why.

Vitamin E is actually a generic name for a group of compounds that are known for their antioxidant properties. This group can be further broken down into two: tocopherols, and tocotrienols.

Tocotrienols in particular have been proven beneficial for hair growth, and just eight months of supplementation led to a 34.5% hair count increase in the studied area!

Vitamin E, especially tocotrienols, is found in a few common foods. These include:

  • Coconut
  • Wheat germ
  • Palm oil
  • Rice bran
  • Olive oil
  • Maize
  • Sunflower seed oil

You can also take vitamin E as a supplement everyday, but it’s better to look for foods that have high quantities of it. These are absorbed more readily by the body.

Folic Acid – Vitamin B9

Foods that contain high amounts of folic acid including peppers and avocados

Folic acid, also known as Vitamin B9, is commonly associated with prenatal vitamins. However, folic acid is an important nutrient even for men and non-pregnant women.

Folic acid and folate are often confused, but folic acid is the synthetic (i.e. created in a lab) form of folate. On the other hand, folate is naturally found in foods and is much better absorbed by the body. That’s not to say that folic acid cannot be used though, as it’s methylated in the liver and then able to be used throughout the body.

But what role does folate, and as a result, folic acid play?

Namely, it synthesizes and repairs DNA (the cell’s genetic material) while also ensuring it functions as it should. This is important for a wide variety of biochemical processes, including hair growth.

It’s best to consume foods high in Vitamin B9, as the majority of this is folate (unless it was intentionally added, then it’s folic acid). Foods that have naturally high quantities of vitamin B9 include:

  • Broccoli
  • Brussels Sprouts
  • Liver
  • Spinach
  • Collard Greens
  • Turnip Greens
  • Mustard Greens
  • Romaine Lettuce
  • Asparagus
  • Papaya
  • Oranges
  • Grapefruit
  • Strawberries
  • Raspberries
  • Lentils
  • Pinto Beans
  • Garbanzo Beans
  • Black Beans
  • Kidney Beans
  • Green Peas
  • Green Beans
  • Celery
  • Beets
  • Squash

NOTE! It’s possible to have too-high levels of folate within the body, and this can increase the risk of cognitive decline. If you suspect you suffer from Vitamin B9 deficiency, or to learn more about the proper supplement dosage, consult with your doctor.


Although not strictly a vitamin or a mineral, this herb is well known in ayuverdic medicine and has anti-aging and anti-inflammatory properties.

While these properties alone can be beneficial in the treatment of hair loss, including AGA, it may also block DHT directly.

Bhringaraaja, known by its Latin names Eclipta alba and Eclipta prostrata, is one ingredient in a commonly used Chinese medication to treat AGA. It’s called BeauTop, and it’s been shown to block DHT and stimulate hair follicle activity.

While further research still needs to be performed, especially on Bhringaraaja alone, its other properties can make it a beneficial addition to your current hair care routine.

  1. Just a question, will these help with women with post-partum hairloss? I have a lot of fellow mothers who are concerned with hair loss after pregnancy. I guess I may be one of the lucky few who do not go through it, but I would love to recommend the above products to those in need.

  2. This is a great list of supplements good for hair loss. I currently take quite a few of them for other reasons. So now I know I get extra benefits with them 🙂 I would really love to have my thick hair back, that would be great. Do you know how long I would have to have been taking the supplements to notice a change in hair? Is this something that has to build up in my system, and then start working?

  3. Great question. Most of these hair loss products will take time before you see results, due to the cyclical nature of hair shedding and growth. I recommend that you give any product a good six weeks, and this includes supplements.

  4. Great question, Mimie! Yes, hormonal imbalance is a leading cause of hair loss in women, and this includes post-partum hairloss as well as menopause. Any of these supplements, especially Nutrafol, can help stem the tide and reverse some of the damage.

  5. I take multi-vitamins already but it doesn’t seem to help with my hair loss, I thought that they had everything in them would I get more benefit from just taking the nutrafol or the viviscal? Would they be ok to take together or should I try them both on their own?

  6. As someone with a family member who has struggled with hair loss for many years, I particularly found the information and advice about some of the natural remedies available really useful.
    I will definitely pass the information on for her to check out.

  7. Hi Penelope! I learned so much! One question I have is, I have been losing a bit of hair lately and I think it has to do with peri-menopause. Is there a recommendation you might have for us in this age group? My good friend has this problem as well, so I am going to send her this link. Great info!

  8. Yes, women usually lose hair during periods of hormonal spikes (childbirth, menopause, peri-menopause, various endocrine disorders including thyroid disorder). All of these are good for any age group – none are designed for any one group in fact. THanks for passing along the info!

  9. Great info, Penelope! I had no idea supplements and herbals would help this condition. I’m thinning a bit at the temple, and hoping to try something a bit more natural and less hype-y. Thanks for this post and blog!

  10. Thanks for the feedback, Terri! Come back and let us know how this stuff, or anything else, works out for you!

  11. I love the idea of taking vitamins, but I also take prescription medication. Do you think it’s a good idea to take vitamins as well?

  12. Always check with your doctor before trying anything, especially if you think there may be a conflict. great question!

  13. I have heard of viviscal and had done some research on it when I was pregnant. I see another poster mentioned postpartum hair loss and that is exactly why I was looking into this product. Since I do not wash my hair everyday, it is nice to know that they provide supplements that can be taken daily. Thanks for the information!

  14. Thanks for the feedback! Supplements are a must in any hair regrowth endeavor. Topical stuff is important but hair health has both external and internal causes!

  15. Hi Penelope,
    I had hairloss periods approximately 4-6 months after giving birth. I have two kids, so this happened both times. I wish I had known about these products at that time. It was terrible for a while. Thanks for sharing the info!

  16. I have changed shampoo after straightening my hair and now I am dealing with hair breakage.
    I have been looking into vitamins and supplements at the drugstore and bought multivitamins for the moment. Reading your article I think a hair supplement would help me, I was thinking maybe ultrax hair rush? To be honest I am a little afraid of buying supplements online. What has been your experience so far?

  17. Thank you ever so much for your top 5 vitamin recommendations for hair loss. I am more than familiar with Viviscal, as I used it for over a year. I stopped, I must admit, as I found it made my hair healthier – no shadow of a doubt – but did not increase it in quantity. I have always had thin hair, hair that lacks volume, and for this reason I have gone to a short cut since 2013, in an effort to gain volume. But I lost hair on the very top of my head a few years ago and, no matter what I tried, that hair does not seem to want to come back. Do you recommend I should use one of the other products? or should I start on Viviscal and keep using it for longer?

  18. Did you notice an increase in hair shed/fall with any of these vitamins when you first started? I tried Nutrafol for 3 weeks and my shed increased dramatically. I’m wondering if it was coinceodence, but my shed had pretty much slowed to normal for almost 6 months.

  19. Actually, it’s common to see an increase in shedding initially. When your hair loss treatment stimulates the hair follicles, providing further nourishment and encouraging regrowth, and once these new hairs start to grow, they push out the old, thinning hairs which is why you may start to lose more hair than normal.

    The shedding stage doesn’t happen to everyone, but when it does, it can last between two and four weeks, as the new hairs make their way through as a normal part of the hair growth cycle.

    Hope this helps, thanks for the great comment!

  20. Hair loss and thinning is such an emotional thing for both men and women. The information about what vitamins and herbs actually work is so helpful. I’m interested in the Ultrax products, they look very effective. I also heard that the thyroid can be an issue for hair loss too, any thoughts?

  21. I just have a question, I have taken hair supplements before (not for hair loss), but I find that some of them has a horrible smell. Do you know if this is the case with any of the ones on your list?
    I don’t suffer from hair loss but based on the reviews on Amazon, there is a noticeable difference for most find the vitamins makes their hair stronger, longer, and fuller. I think this is a good idea for me, because I have excessive breakage from too much chemical such as hair dyes.

  22. I think you might be talking about the stinky mighty B vitamin! All of the supplements on this list are gelcaps, so little to no smell luckily! Great question. And yes, hair loss vitamins are a specialty niche and tend to be higher quality, because the people who make them know we consumers have many choices!

  23. I have read your review of number 4 Hairfluence. My hair is starting to thin around my hairline in the front because I started to wear a wig when I go in public so I was thinking about taking a supplement. I am glad I have received so much valuable information from your site.

  24. You should absolutely take a supplement, because wigs can endanger your scalp health and circulation. People have great luck with Hairfluence, give it a shot!

  25. Do you know anything about New Chapter’s Perfect Hair Skin and Nails? I asked my holistic pharmacist if he had any recommendations and he said people seem to really like that. The ingredients don’t tell me much:

    Biotin (from culture media) 300 mcg 100%
    Organic Haematococcus pluvialis algae
    Astaxanthin 4 mg 120 mg *
    Organic Reishi (Ganoderma lucidium, Ling zhi)
    (mycelium and fruiting bodies) 100 mg *
    Stress and Energy Support Blend (from culture media)
    Organic Schizandra (berry), Organic Maca (root), Organic Chamomile (flower) 56.2 mg *
    Digestive Support Blend (from culture media)
    Organic Aloe (leaf), Organic Peppermint (leaf), Organic Coriander (seed), Organic Cardamom (fruit), Organic Artichoke (leaf) 37.5 mg

  26. Hey will. Great website. I just started taking zinc supplement about a month ago. It’s through Mega Food and is 22.5mg. Is this considered high dose and can this dose cause increase in DHT or cause hair loss. Thanks!

  27. i am suffering from receding hairline and hair is thinning out from past few months, what should i do??
    what diet should i follow and can i regrowth my hair through nail rubbing exercise ??
    please guide me….

  28. Hi Matthew – I would recommend trying these supplements one at a time rather than in combination. Great question, though! Start with Nutrafol for men – that seems to do the trick. It was designed and meticulously researched by a male model who didn’t like the sexual side effects of propecia.

  29. I buy supplements online all the time, but I go through which is a trustworthy vendor available most places in the world. Most drugstore vitamins are crap – they’ve been on the shelf way too long, and they’re mostly rancid oils, sawdust, and fillers. It’s much better to get a medical grade, quality supplement from the internet or even a supplement store.

  30. Thanks for sharing your experience with Viviscal, Giulia! I’m happy to hear it made your hair healthier and not so happy to hear you didn’t experience new growth. I think you should try Nutrafol, and a low level laser device. Try them in combination religiously, for at least four months, and see if you notice a difference. It depends on whether your follicles are dead or merely dormant. is there any hair at all – vellus or baby hair? At any rate, given how much time has passed, you will need to act aggressively now with simultaneous treatments.

  31. Thanks for the comment, Linda! Yes, the thyroid is exactly why my hair has been such an issue. The most commonly prescribed thyroid medication, Levothyroxine, can cause hair loss. That, and a body struggling to maintain itself metabolically tends to let ancillary things like skin and hair health fall by the wayside. The Ultrax products are among my favorites, I’ve used and reviewed several of them – shampoo, serum, and hair mask. thanks for reading!

  32. Hi Joanne! I don’t know anything about this supplement but from what you’ve listed, it has some promising ingredients, including mushroom fibers (mycelium). I had to google Astaxanthin – it’s an antioxidant pigment found in marine life. so if you have a shellfish allergy this supplement would be a definite no-go. I’ve never seen coriander or cardamom in a hair loss product. It has a 3.5/5 on, from 56 reviews, which isn’t bad…most importantly for you, there’s no Saw Palmetto, so it would hopefully not have the same hormonal effects. If you decide to try it, come back and let me know if it helps!

  33. Hi,
    I take Opti-Men multivitamins with breakfast and follihair tablets with lunch. Is it ok taking two kinds of multivitamins in a single day?

  34. I have tried everything..from laser comb to scalp laser treatments to biotin you name it. My hair was so thick as a child I had to get it thinned out. Since my 30’s the top of my hair thinned out terribly and I’ve been wearing a unit ever since. I lost my natural wave in my 50’s and my hair is thin and straight on sides and back. Very thin on top. It’s funny how many compliments I get with my unit…only a few know it’s not my real hair. Can DHT be blocked naturally? I think once it’s gone, sadly it’s gone.

    • Hi Mary,

      There are a few natural DHT blockers, though they have their own side effects. You can learn more about them here:

      Unfortunately, you’re right that once the hair follicle has died there is no way to regrow the hair. This can take a few years, though the number of years will vary from person to person.



  35. 200% perfect. Foods high in zinc, copper, selenium, biotin, vitamin C will reduce DHT causing Dry skin, aggravates psoriasis, joint pain, mood swings.
    Remedy: calcium 250mg+ vitamin D3 800IU +Boron 1mg per day with avoiding zinc, copper, selenium, biotin, Vitamin C, Folate and Niacin.

  36. Perfect information.
    It’s very very dangerous to inhibit DHT is expressed all over the body ..scalp, skin, bones and joints, muscles, male reproductive organs. Hair could be replaced by hair weaving patches… particularly ..Zinc, selenium, copper, biotin, vitamin E are potent DHT inhibitors even if applied on skin causing Dry skin, flare up of psoriasis, joint pain , muscle weakness and male sexual dysfunction.
    Remedy: popup DHT by excercising.. HIIT and cardio, slimming, eating sugar and fat /oils without Vitamin E , reducing folate and vitamin C intake, avoiding foods having more than 0.2 mg zinc, copper, selenium and biotin more than 1ug, eating calcium rich foods and taking supplements.. calcium 500mg + Boron 1mg+Vitamin D3 800IU per day and drinking 100gms of sorghum grain extract daily with 100gms of Raisins.
