DHT Blocking Hair Loss Shampoo – Professional Strength Review

DHT Blocking Hair Loss Shampoo, by Hair Restoration Laboratories, is exactly what it sounds like. It’s completely loaded with herbal DHT blockers.

This latest release includes a few additional DHT blocking ingredients and 25% more active ingredients than their regular strength version, which I’ve also previously used and reviewed here.

According to their website, Hair Restoration Laboratories has been a successful hair loss treatment company for over 10 years. This shampoo is based on latest science on how to defeat about that pesky testosterone byproduct, DHT.

DHT is main culprit behind hair loss for both men and women. This latest formulation is more intense and aggressive for those wishing to quickly arrest their hair loss due to excessive DHT (ie: MOST of us!)

As a major bonus, this DHT blocking shampoo is also SULFATE-FREE and PARABEN-FREE.

DHT Blockers & Hair Loss

The excessive presence of DHT, or Dihydrotestosterone if you prefer the big word version, is one of the main causes of hair loss for men and women.

If DHT had its way, we’d all have bald scalps and hairy bodies. Yup, you read that right: the same hormone makes our bodies hairier and our heads balder.

DHT attaches on androgen receptors on hair follicles, and then triggers the receptors to begin miniaturizing those follicles. Miniaturized follicles = thin, weak, and going going gone hair.

DHT on hair folliclesA 1998 study showed that both plucked follicles and skin from a balding scalp contain higher levels of androgen receptors than those from a non-balding scalp.

Some people simply have a genetic susceptibility to otherwise normal levels of circulating androgens, particularly DHT. A combination of hormonal and genetic factors could explain why some people are more likely than others to lose hair.

Do DHT Blocking Shampoos Work?

Yes. Keep reading to see why.

This professional strength shampoo contains MANY DHT blockers, including:

  • Salvia Miltiorrhiza Root Extract
  • Studies establish that this extract improves blood circulation to the hair follicle.
  • Ligusticum Chuanxiong Root Extract
    Studies establish that this extract has a beneficial effect on hair, reduces hair loss and helps makes hair silky, glossy and manageable.
  • Astragalus Membranaceus Root Extract
    Known for its adaptogen properties, this extract is rich is polysaccharides, which are nutrients critical to hair follicle health.
  • Camellia Japonica Seed Oil
    In research studies, this extract has demonstrated potent antioxidant properties with the ability to inhibit the production of DHT.
  • Argania Spinosa Kernel Argan oil
    A natural oil that is rich in vitamin E and essential fatty acids. This ingredient provides extensive conditioning and helps combat hair dryness and damage, in addition to diminishing frizz.
  • Biotin (Vitamin H) 
    An essential B-vitamin that promotes hair growth and aids in overall hair health. This ingredient strengthens both the hair follicle and the hair shaft, from which the hair grows.
  • Soy Isoflavones
    Studies establish soy isoflavones promote hair growth by increasing the dermal levels of insulin-like growth factor (IGF-1).
  • Tocopherol
    Also known as Vitamin E, this ingredient is an antioxidant and intensive hair conditioning vitamin. This ingredient also softens the hair, provides essential healthy-hair nutrients, and soothes and protects the scalp.
  • Nicotinic Acid/Niacin
    Niacin and hair growth go hand-in-hand because this B vitamin boosts energy and improves blood flow to the scalp. A healthy scalp is crucial for healthy hair growth.
  • Nigella Sativa Oil
    Studies established that sativa increased hair growth and was effective in treating telogen effluvium, a specific hair loss condition and pattern primarily experienced by women.
  • Hibiscus Rosa-sinensis Extract
    Studies of this leaf extract established that it promoted more hair follicles in the anagen (growth) phase.
  • β-sitosterol
    There are several reasons that may explain why phytosterols can be helpful in the treatment of hair loss. One of their main characteristics is their anti-inflammatory properties. Inflammation is often one of the characteristics that can contribute to hair loss and several studies have established that phytosterols have great anti-inflammatory purposes.
  • Citrus Medica Limonum Oil
    A fragrant natural oil that is rich in Vitamin C and is a powerful antioxidant that helps protect the scalp and hair from free radical damage.
  • Polygonum Multiflorum Root Extract
    Studies establish that this extract is a highly effective anti-androgen by decreasing the presence of DHT and obstructing 5-alpha-reductase enzymes.
  • Rosemarinus Officinalis Leaf Oil
    Certain studies have established that rosemary oil can be just as effective as minoxidil and stimulate hair growth.

*New Ingredients Included In The Professional Strength Version:*

  • Cayenne fruit extract 

According to my friends over at Nutrafol, which also employs this ingredient: “The most important element in cayenne peppers is Capsaicin which produces a tingling sensation on the skin. It stimulates the skin cells which increases the overall metabolic process of the skin on a cellular level. Due to intensive metabolism, blood rushes to the skin of the scalp and the hair follicles receive sufficient nutrition and oxygen content from the blood flow which greatly promotes hair growth. Also, Capsaicin stimulates the dead skin cells of the scalp which leads to new hair follicle production.”

  • Pygeum africanum bark extract

Pygeum africanum is an evergreen tree from Africa. The extract is rich in derivatives of natural fatty acids and is used in herbal medications to relieve urinary symptoms caused by benign prostatic hyperplasia (BPH). Excessive DHT happens to be the main cause of BPH (or prostate enlargement) and is also considered the main culprit in causing male as well as female pattern baldness.

  • Pumpkin seed oil

Pumpkin seed oil has been shown to block the action of 5-alpha reductase. The enzyme 5-alpha reductase is the main antagonist in androgenetic alopecia.

  • Caffeine

A 2015 German study showed that caffeine stimulates hair growth in hair follicles in petri dishes. Therefore, caffeine is a powerful DHT blocker that shows up in basically all new hair loss shampoos.

What Customers Say:

Users are happy with the value they get from the 16 oz bottle, especially after a first purchase ringing in under $30.

After a month or two of use, women have observed an improvement in growth around the hairline, and a general thickening of the individual hairs.  Few reported irritation or other allergy-related issues.

My Experience Using Professional Strength DHT Blocking Shampoo:

Like the regular strength version, this Professional Strength version has a “gender-neutral” smell – it definitely is ok for both men and women to use.

A lot of supposedly unisex shampoos say they’re gender neutral, but then they smell excessively floral, or, worse, in the same neighborhood as Axe Body Spray…which no woman wants to smell like! This is really none of the above.

It KINDA reminds me of the smell of the shampoo, Prell, if anyone here is old enough to remember it!


DHT Blocking Hair Loss Professional Strength Shampoo comes up with a good lather and thickness (some hair loss shampoos are obscenely thick- too thick to be workable).

it doesn’t burn or tingle when leaving it on my scalp for the recommended 3-5 minutes.

I always appreciate a pump bottle design – in the shower the last thing I want to do is more work – lifting a bottle, squeezing sh*t out, putting the bottle back again. The pump design appeals to the worse angels of my nature 🙂

And, perhaps most importantly, through my hair loss treatment journey and use of DHT blockers, I’ve come to accept that DHT is the big nasty culprit behind most hair loss, including behind mine.

I’m convinced everyone struggling with hair loss needs to use a good DHT blocking product, whether it’s shampoo or serum.

labelsWhy use the professional strength version of this shampoo?

Many of us are familiar with DHT blocking ingredients and have no known reactions or allergies to them. For us, I say it’s best to jump right in with the more intense formulation. I have moved on to the professional strength version of this shampoo with no reactions or issues.

For anyone hesitant about any of these ingredients, or even just for those with an unusually sensitive scalp, I’d say it’s smarter and gentler to start with the base model of this shampoo and see if you can tolerate it.

You can always upgrade to the professional strength for your second bottle.

Overall: STILL a Great Budget Option for DHT Blocking Shampoo

Some of these hair loss shampoos, particularly professional strength options, run over fifty bucks for a much smaller bottle, and that can be SOOOO off-putting for people on a budget that they don’t pursue any treatment at all….which is a bad idea!

piggy bankMost shampoo bottles run in the 8-10 ounce range, not 16 full ounces. Here, you get a huge bottle for the price.

Depending on the length of your hair, this bottle of shampoo will last two to four months, giving you even more value.

Speaking for myself, using it exclusively on my very long hair, it lasted almost two months.

IDEALLY: you should combine this topical treatment with a supplement-based treatment for best results and most aggressive strategy.

For example, if you already are taking a powerful hair-loss supplement, this can be the budget-friendly but potent hair loss shampoo treatment you use to cover your bases.

Comprehensively address the root causes of your thinning hair both on the inside and the outside.  You’ve got limited time before those follicles die for good!

  1. Great site, Penelope! Lots of well-researched information. I will definitely have to try some of these recommendations for my thinning hair. Thanks for making this useful information about Natural Remedies available.

  2. Thanks for the review. Do you find DHT blocking supplement products work better than shampoos. I am 23 and am starting to get a receding hairline. My hair will grow long on the top and everything but it’s just the hairline that’s annoying. Is it possible to restore the hairline back to its normal place when I was younger or do these products just slow the process? And also what is your strongest recommendation for this for me? Would a combo of shampoo and supplement work?

    • Thanks for the great question. yes, if your hair is just starting to recede, NOW is the time to start an aggressive treatment plan including this shampoo (or something else containing caffeine and DHT blockers) as well as supplements. You might also want to consider low level laser therapy. Your follicles are most likely weakened and dormant, and not dead, meaning they can be brought back to health with the right combination of tools.

  3. Very interesting article. Your recommendations are always so thorough. This looks like a great product. I never knew about DHT. Weird that is causes baldness yet increases body hair! Great article, thanks! ?

  4. Blocking Hair Loss? I don’t think that I have come across a shampoo that actually works and thickens the hair on my balding head. I have tried shampoos, cream, organic recipes, even old wives tales of garlic and honey for my hair loss…and nothing has worked so far. Do you know anywhere that gives out samples to try before you buy?

    • I understand the impulse behind your question, for sure, but the thing about hair loss treatments (any of them, sadly) is that they take several weeks to several months to start noticably working. A sample woouldn’t provide you enough time to test it out. You’ll just have to keep biting the bullet – I’d recommend something strong like this with many clinically proven hair loss fighting ingredients.

  5. I am so glad that there are formulations like these on the market now, and that we have choices in the way we want to improve hair growth and minimize loss to normal. I know of many people who are dealing with excessive hair loss and could really benefit from this information. I had no idea that there was so much research going on in this area! Thank you for this article.

    • Thanks for the great feedback. It is really amazing that we have so many great choices these days – hair loss doesn’t have to be permanent!

  6. Why do I feel like I am always on your website. This product is obviously inexpensive for all that it does. I do have a question, you mentioned that it was for both men and women. Can children use this product also?

    • It’s probably best just for adult men & women – children are rarely affected by hairloss due to an excess of the hormone DHT. I’d use cheaper/less intense stuff for them, for sure!

  7. Thanks for the great article Penelope! I always find great detail in your articles, that I never have to go searching anywhere else.

    I appreciate all the help and support you provide all your readers. Always unbiased in your reviews.

    Looking forward to the next product!

  8. Hi Penelope, this dht blocking hair loss shampoo looks amazing and very effective, as you have explained all the ingredients and qualities of it in a really nice way. I will share it with others so that people can order and try some. I am sure they will find it really good and effective. I have been using hair growth products after reading reviews from this website and believe me all turned out awesome. I am sure this shampoo is excellent too.

    • Thanks for the feedback, you can always give this one a shot as well, particularly if you’re on a restrictive budget. Lots of bang for your buck here!

  9. I always learn something new when I read your articles, in this case about herbal DHT blockers. Yes, it’s true I have noticed that Caffeine is an ingredient in some hair loss prevention products. It is not surprising that it is also a component f this shampoo.Is this shampoo suitable for natural (African) hair? I am asking because most hair loss prevention shampoos that I have recently used have somehow damaged my natural hair but my friends (who have no natural hair) don’t get the problems I get from using these type of shampoos (it works perfectly for them). Maybe there is a component that doesn’t go with my hair type?

    • This is a great question. To my knowledge, none of these ingredients damage african or textured hair. I know sometimes women with textured hair have issues with the ingredient Keratin, but that is not present in this shampoo. I’d say give it a shot, and you’ll know right away if it’s harming your hair – you can return for a refund, if so.

  10. Penelope

    As usual a very informative, well researched post. I like reading your reviews as you have done such a thorough job on them. My biggest concern with this product is that it has such a long list of ingredients, and whilst I’m not allergic to any on that list I would be worried about possible interactions. I suppose the best way to test would be a small patch test to ensure no allergic reaction – would you agree?


    • A patch test is a fantastic idea, somewhere on your hair and scalp that isn’t visible. If it feels and looks good, you should be GTG. I appreciate your caution here, as allergies are very common and we must always be careful when trying out new products.

  11. The large bottle for the price is appealing for anyone looking to treat hair loss without breaking the bank. I wonder if 14 days is a long enough money back guarantee period though? How long to typically see noticeable results? Great to see it’s sulfate and paraben free! What about silicone? Thanks!

    • 14 days is enough to see if you’re having a reaction to any of the ingredients, but the sad truth is these products don’t really show their worth until a few months in, most of the time. It’s a great question. Silicone is not in the ingredients list!

  12. This is another great review. I love the details of your review. I always learn new things. I had no idea the same hormone that makes our bodies grow hair also makes our heads go bald. My husband is suffering from hair loss. He is starting o lowly losing hair. Do you think this product will help him? Do you know how long would a bottle of this shampoo cause?

    • Thanks for the great question. If your husband has short hair, this will last him an unusually long time, my guess is 4 months, because it’s a huge bottle (16 oz) and he probably only needs one pump per wash. If he’s starting to slowly lose hair the time to start treating it aggressively is now, while his follicles are still alive and can be rehabilitated. I would recommend you start him on this or another DHT blocking shampoo that contains caffeine, and get him on a hair loss supplement like Nutrafol.

  13. Having learned from you how DHT blocking shampoos can be useful I was excited to read this review. It is always great to learn the culprit behind different ailments so you can treat them better. I love how this shampoo if friendly on your wallet. I don’t like to buy cheap products when they matter in an area such as hair care and this price is very reasonable. The pump action bottle is great, it makes it much easier to wash your hair. Thanks for another great review!

    • Thanks for the feedback, and I’m glad that this product is available at such a good price. It’s a great way to test out a formulation with so many different DHT blockers. And I think ALL shampoo bottles should be equipped with pumps, btw!

  14. Well, I don’t like the sound of this DHT thingy at all! I have never heard of it so this was an education for me today. And I love the look of this shampoo, what a great list of ingredients all of which are proven to help with hair loss problems. They have packed so much stuff into this shampoo for a relatively small price tag so it’s definitely worth a try. And I can totally see how cayenne could stimulate hair growth, makes total sense being as peppers of all kinds have a stimulating effect. Brilliant!

    • Thanks for sharing your thoughts, Stefanie! It’s incredible how useful that cayenne pepper is, right? I know it helps us out with boosting metabolism and intestinal healing, as well as anti-inflammatory effects. There are even topical products that use it as a pain relief agent. I was happy to learn more about its role in fighting hair loss, too!

  15. Really good information and great detail.
    Can you do one for me for shampoo that will reduce/remove the gray from my hair?

    • Grey is tricky…natural solutions include both Rosemary oil and henna. This site is geared far more toward the existence of hair rather than the color of it…but check out Rosemary for sure!

  16. Oh, how I wish my hair loss was addressed by this shampoo. But alas, I am suffering from alopecia universalis. Still searching for my hair loss cure. Right now, I’m trying out an autoimmune diet protocol. I’ll keep checking back here for natural remedies!

    • Thanks for leaving this feedback. One type of treatment you might want to consider is low level laser therapy…this is helpful for the type of alopecia you are experiencing. Read more about it and check out some laser hair loss devices here.

  17. Great post! Didn’t know that DHT existed and that it was THE answer to hair loss!
    I am so glad I found your post!
    Thanks for sharing this important information! Now I know what to look out for!
    Cheers – Orion

  18. I have a secret. I have thinning hair at the top of my head. Shhhhhh. Don’t tell anyone.

    This information about DHT is very helpful. I never knew of this before. Now I know, I will start to use shampoos that block DHT. And DHT Blocking Hair Loss Shampoo, by Hair Restoration Laboratories sounds like the right shampoo for the job.

    I am currently using another anti hair loss shampoo. I will switch to this after I am done with that shampoo, which is almost empty. One question, is the shampoo alone enough? Do we need to get any conditioners or treatment or essence?

    • Hair Restoration Laboratories is about to release a conditioner with DHT blockers, too. I would say try that, or even get yourself some root spray. OGX has some really affordable caffeine root spray that blocks DHT, it’s under $10 and you can find it here.

      Come back and let us know how this shampoo works out for you!

  19. I think I’m DHT’d to the max as I’m suffering from thin top and hairy everywhere else. Only if I could reverse it so it was the other way.

    This looks like a great product Penelope. I’ve always has success with your products.

    Will this also help with dry scalp?

    • Thanks for the great feedback, really appreciate you sharing your thoughts! For dry scalp, I’d recommend a moisturizing treatment like a scalp mask. There’s an excellent one specifically for folks with hair loss here.

    • It’s for normal consumers like you and me, but it contains professional strength ingredients for targeting the root cause of hair loss in men and women, which is an excessive presence of the hormone DHT.

  20. Interesting post. Thanks for sharing the details. Curious to know how this compares to everyone`s favorite: Rogaine. In your opinion what`s the better product and why? Looking forward to your response!

    • Hi Eve- thanks for reading and sharing your questions. Rogaine is a topical overnight treatment that you use in addition to something like this, a DHT blocker. There are no contraindications to using them together for maximum results. Some people have terrific luck with Rogaine and I’ve also written a review of it here. Others focus on DHT blocking shampoos, conditioners, serums, and supplements.

  21. I love that this has natural ingredients instead of just a bunch of chemicals. My mother’s hair has started thinning, but she is very particular about what kind of ingredients she puts on her skin. This might be the answer for her! Thanks!
