DHT Blocking Hair Loss Shampoo by Hair Restoration Laboratories: Review

Whew! My review of this DHT blocking shampoo is way overdue, but I’ve actually used this one, so it’s important to tell the world all about it.

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

According to their website, Hair Restoration Laboratories has been around for over 10 years, and has created a shampoo based on on the latest science about that pesky testosterone byproduct, DHT.

DHT is main culprit behind hair loss for both men and women. As a major bonus, this 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.

A 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.

Ingredients that block DHT:

This shampoo contains MANY DHT blockers worth noting:

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 in 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

An argan fruit

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).


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

A niacin supplement

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.


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 hair growth promoter.

Rosemarinus Officinalis Leaf Oil

Certain studies have established that rosemary oil can be just as effective as minoxidil and stimulate hair growth.

What Users Say:

People are pleased with the value they get from the 16 oz bottle, especially after a first purchase ringing in at under $15. After a month or two of use, people have observed an improvement in growth around the hairline, and a general thickening of the individual hairs.

My Experience:

This shampoo absolutely has a “gender-neutral” smell – it definitely is ok to use for both men and women.

Often men are worried about these unisex shampoos being too “flowery” and likewise women are worried about them being too Old Spice or Axe Body Spray 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 Shampoo has a good lather and thickness (some hair loss shampoos are obscenely thick- too thick to be workable), and 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 🙂

Because I used this shampoo in conjunction with the Grow New Hair Faster by Just Naturals, it’s hard to isolate the effects of that shampoo away from the other treatment I was using. But I will say that when I used both together, I noticed an improvement in my thinning hairline and an increase in baby hair around my face.

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.

Overall: Great Choice For People on a Budget

This is an excellent hair loss treatment choice for people on a tight budget. Some of these hair loss shampoos 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.

In my view, it’s much better to use SOMETHING with DHT blockers than nothing at all, and that’s why I recommend this DHT Blocking shampoo, especially for people watching their pennies who would never be able to afford these super expensive mainstream alternatives.

More importantly, you get a huge bottle for the price. Most shampoo bottles run in the 8-10 ounce range, not 16 full ounces. 16 ounces for under $15 is a win in hair loss treatment land.

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 can combine this treatment with another one for best results. For example, if you already rake a powerful hair-loss supplement, this can be the hair loss shampoo treatment you use to cover your bases.

Comprehensively treat your hair loss problem both inside and outside – you’ve gotta!

  1. Great review, really enjoyed reading it. I loved the fact that we have the option of 14 days guarantee money back return. Most companies I have used before don’t offer that.

  2. Hi
    Great read.
    I think both me & the wife could do with this product ? My wife loses hair a lot but still has a full head, I hardly lose any and look like a monk ! lol
    we will have to find it in the UK.
    Thanks for the review

  3. Hi Paul – this product might not be available in the UK so I would recommend that you order it straight from their website, on any of the above links. Thanks for leaving your feedback!

  4. Isn’t it something how we have more hair in the unwanted places… especially for us women… 🙂 It was Interesting to read about the DHT, and the DHT Blocking Shampoo is reasonably priced. I would think this type of product would cost much more; we all know how toiletries and beauty products have skyrocketed… especially for something like hair loss treatments.

  5. Thank you for the comment, and yeah, I completely agree with you about how odd it is about the price of beauty products, and this shampoo is so reasonable compared to most of the others!

  6. Thank you for the review. This will definitely help me a lot as I can use this information in my future posts (of course with due credit to you) if you do not have a problem, that is.
    Thanks again

  7. This sounds just like a product I could use. I still have lots of hair but find that as I shower and wash my hair, the plug gets blocked with hair that I have lost and I swear it lose more and more each time it gets a wash. I am from the U.K and I saw from another comment it is not available here. I will take a look at their site and see what the shipping is to the U.K

  8. This is great information. Do you have any products or reviews for people with alopecia universalis? I know quite a few women who have lost all their hair due to an autoimmune condition rather than DHT levels.

  9. Interesting post. I have been recommended some medication based on Finasterid. Any eperience with that one?

  10. I’m always sceptical about these types of shampoos that claim to make your hair grow back that’s why I have never bought any but with the 14-day money back and the $5 coupon it has to be worth a try and get over just wondering if they work so thanks for this

  11. You’re super welcome! Yeah, it’s hard to go wrong at this price point, especially after breaking it down and seeing just how many different DHT blockers – the active ingredients – are in this shampoo.

    I agree that it’s good to be skeptical about miracle cures. What sets us apart today, even from this kind of thing 20 years ago, is the science and research that’s gone into understanding what causes hair loss, and what tools we have to address those biological causes.

  12. What a Great product. I’m in my twenties and starting to see some thinning. Hopefully that’s all that’s gonna happen, but it’s good to know that there are solutions and products to help prevent it.

  13. You’ve gotta start treating it now, when your hair is thinning, rather than waiting until the follicles are dead. That’s the only foolproof strategy, unfortunately. My dad was bald by the time he was 16 – age has very little to do with it, unfortunately!

  14. It’s both, if the cause of your hair loss is excessive DHT (which is the most common cause for men and women both). For suffering and weak follicles, it provides strength and support, including regeneration for follicles that haven’t reached complete root death.

  15. There can be so many reasons for hair loss and it can be so frustrating not knowing why you are losing hair in handfuls. I only ever notice hair loss when my hair is longer. But I have a lot of hair 🙂 Great review.

  16. Yeah, it’s true that sometimes long hair falls out more than short hair, because the weight of the hair strains weak follicles and is more likely to dislodge. great observation, thanks!

  17. This shampoo is definitely budget friendly. A few years ago I had to purchase a similar product and there was not much out there. I paid a very high price for a very small bottle. My daughter takes bio-tine so I know it is good for hair and nails. She suffers from thinning hair and is always looking for good products, I will be sharing this article with her.

  18. Thanks for the feedback, and for sharing the info with your sister! you’re definitely right – MANY hair loss products come in at a much higher price for not nearly as much product.

  19. This is exactly what I have been looking for (sadly so) an affordable hair loss prevention shampoo. I am willing to give it a try, because the other stuff hair salons have been trying to sell me, cost $50 or more every time. Sorry, not in my budget. Thank you for the in depth explanation of the ingredients. I will also let me girl friend know – a unisex scent is never a bad thing. Thanks, again for the great review !

  20. glad to help you find what you were looking for! It’s important for those of us on a budget to know there are options and not get swindled tooth and nail out of our hard-earned pennies. happy shampooing!

  21. does this do anything to block PGD2? I had my blood test specifically for that, as I’ve been losing hair and noticing and not growing back for about 15 years, (my body has gone through much stress, died many times), and thought that might be a culprit. It was elevated quite a bit. That would be wonderful if the shampoo does that, too.

  22. Interesting read, I like the fact that this shampoo is SULFATE-FREE and PARABEN-FREE. I’m all about healthier ingredients. How long does it take to see results if you use this everyday? Im thinking of my husband here as he is slowly loosing his hair. I guess this could also work as a preventative solution if I used it. I will be considering this item for sure. Thank you.

  23. The bottle says you’ll see results by three months; I tend to think you’ll know if a hair loss product is working by two months. If he’s starting to lose hair, now is the time to treat it, because you can treat weak follicles but not dead follicles.

  24. Interesting read about DHT Blockers & Hair Loss. The shampoo has many benefits and looks like a good product . I like the fact that it doesn’t burn or tingle. My mother suffers from dandruff and has tried other shampoos that left her with the feeling of burning or tingling. I know it is a shampoo specifically for hair loss but would you recommend this shampoo for people who suffer from dandruff and hair loss?

  25. Thanks for your thorough review of this product.

    And for addressing this sensitive topic. I think this is something many women suffer from but aren’t comfortable enough to discuss.

    I feel I’m able to make a good decision after knowing all the ingredients and understanding why this product is going to help me.

  26. Hey Penelope, I came across your side while looking for a hair loss prevention for my mother. This seems to be a very good product and the fact that you did try it is even better. I will use the coupon and get it for her. Thanks for sharing!

  27. What a nice daughter! Thanks for the kind words and I hope it helps your mom. At this price point, it’s certainly worth a shot 🙂

  28. Been looking at my hairline recently, I think this might just be what I need! Do you know whether this is a vegan friendly product, ie: no animal testing or animal ingredients?

    Such a great resource! I’m a guy, but have mid-back length hair, so the hairstyles and tips for thinning hair are amazing, thanks!

  29. This is a vegan product, great question and thanks for asking. And yes, I’m glad that men can get some value from all the info on this site. Many products are for both genders, including this one!

  30. I am one of your skeptics, must admit i find it difficult to believe that a shampoo is going to restore hair loss or prevent hair loss.

    How does this shampoo “block DHT”? Where does the DHT come from?

    Do you think it would be off assistance to a person who has lost a lot of hair?

  31. Skepticism is ok! Thanks for the questions.

    DHT, dihydrotestosterone, is a by-product of testosterone in our bodies, in both men and women. It acts like an androgen and attaches to the follicles and shrinks them. Sometimes they shrink so small that no hair, or only tiny baby hair, can get through. Excessive DHT will lead to excessive hair loss and weakened follicles. When you block it, the follicles have a chance to “breathe”.  

    DHT blocking shampoos are good for people who’ve experienced a lot of hair loss as long as their follicles aren’t entirely dead. You can bring back a dying follicle but you can’t resurrect dead ones. When people look bald or their hair is noticeably thinned, it is sometimes the case that the follicles are just weak but still alive. Someone totally bald for many years likely has more dead than weakened follicles.

  32. Hi again! So I’m thinking I need to try a shampoo. If you had to pick one that wouldn’t break the bank, which of the several you’ve reviewed would it be?

    At the moment, I’m most eager to just stop the shedding. I’ve started the Collagen Peptides, which has done wonders for my body aches if not yet for my hair; and just switched from the Viviscal which after a year stopped working to Propriden. We’ll see. Also, I had my thyroid tested and it’s normal, so whatever’s causing this–most likely aging–it’s not that.

    Thanks again for your terrific blog!

  33. Thanks! Yes, I have curly hair. I think I’m going to try the OGX since it looks like a Walgreen’s near me has it in stock. So that’s cheapest and quickest.

    I’ve been using a combination of rosemary, cedarwood and lavender essential oils in fractionated coconut oil, but only a few times a week, since it makes my hair a bit oily (understandably!). I generally only wash my hair once, maybe twice a week, and right now I’m sort of terrified to. The last wash netted me a truly scary clump 🙁 🙁

    The Ultrax sounds amazing. Do you know if it’s ok for color treated hair?

    I also haven’t had my hair cut since February (!) and am wondering if that actually might help. Layers could help cover any thinning patches and it’s possible the weight of it is contributing to the shedding…


  34. Great review, it sounds like a good option to start with if you don’t want to break the bank. I enjoyed reading your own experience with this product. The fact that the shampoo has kind of a neutral smell to it makes it a good option for men as well.
    Thank you for this very detailed review.

  35. Ultrax is ok for color-treated hair. Come back and let us know about how the OGX Fight Fallout works for you, and you can always splurge for the Ultrax if you don’t see the results you want.

    And YES, get a haircut. The weight of long hair pulling on weak follicles can lead to more shedding.

  36. Great article, Penelope! It is extremely helpful to be informed of possible hair loss causes. At least I now have a mental inventory of what I need to use if I ever cross paths with hair loss in the future.

  37. Great review. I found the information very helpful and useful. My dad has suffered from hair loss for many years. He has tried many products and nothing has ever worked for him. He simply gave up. This product sounds like it might work. I probably will buy this shampoo for my dad for the holiday. Thanks you for the review.

  38. thanks for the comment, Hong! I’m sure your dad will appreciate this shampoo, and your thoughtfulness for the holiday 🙂

  39. My hair is thinning, colored and very dry and frizzy. I would like to try this shampoo but will this shampoo make my hair feel like straw like a lot of these shampoos do? Thanks for the info.

  40. Thanks for the comment. My hair is a lot like yours, and I haven’t had that experience using this shampoo. Of course, use it alongside a conditioner or at least a rosemary/vinegar rinse. Try it out and let us know what you think -and get your $7 savings with the coupon code 7off!

  41. I’m glad you actually have used this product. It gives your review lots of credibility. I think I’ll try this. Thanks so much.

  42. I’ve had my fair share of hair loss. Lucky for me, it’s close to the neckline, so easy to cover up with the rest of my hair. I’m not familiar with DHT. However, I’m convinced the all the chemicals companies are having us buy are having a negative effect on our bodies, both inside and out. I’ve been trying to go more natural lately (less chemicals) with my body.

    Living in southern Nevada (extremely hard water), I wonder how DHT compounds the effect of hair loss.

  43. That’s a great question, the interaction of hard water and excessive DHT hormone in our bodies. I would recommend washing your hair as infrequently as possible and when you do so, use a DHT blocking shampoo.

  44. Hi Penelope,

    I am a person who has very long hair. One of the things I noticed about products that help to grow hair and retain length is that they contain natural ingredients. I like using products that contain vitamin e, b vitamins, argan oil, rose or some kind of protein. I feel that they work better to actually nourish the hair.

    I also notice that many shampoos on the market are no different that dish soap. They dry the hair out making it weak and causing damage. A shampoo like this, with quality ingredients, will give someone healthier hair over time which would lead to growth and length retention. I know this because I use products with ingredients similar to this one. People really underestimate the importance of quality ingredients versus chemicals for hair growth.

    Excellent review!

  45. Hi Kyanna, thanks for the great comment. I’m glad that you have such awesome hair and I LOVE LOVE LOVE your comparison to “dish soap” because that’s what most grocery store shampoo is. I agree, argan oil, protein, vitamin E are all excellent. The DHT blocking ingredients in this shampoo take it over the top in helping women who are struggling with hair loss, bring life back to their follicles.

  46. Hi Emily and Penelope, My hair too is very very dry and breaks easily. I used to use this product and found that it was just like a normal shampoo and it really does help with the hair growth and strength. I’m happy to have stumbled on your site because I couldn’t get it in the UK but I see that they ship to the UK with no postage fee! Thanks. x

  47. THanks for the comment, Jo! I’m so glad you can get this shipped to the UK and that you had great results with it!

  48. Great information about DHT and treating hair loss, its packed! I would definitely give it a try.

  49. Thank you for sharing the info I found the details very helpful This is a very interesting and helpful post This post contains huge valuable information on our hair loss. This article can help prevent the risk. Truly it’s a nice job.

  50. Hi,would this product be good for me ad I suffer wth thyroid issues(Hadhimotos)and my hair is thinning ?thanks

  51. Hey Penelope,

    Thanks for your great informative blog! I just loved it and thoroughly enjoyed it while reading. You share some great hair loss solutions that are really valuable. I will definitely try this product.

  52. Yes, it definitely sounds like this product will help you with hair loss, and strengthen your follicles so you shed less! They do ship internationally, so even with the cost of shipping it might be less pricey than other DHT blocker shampoos. As another suggestion, there’s a product that’s even more prevalent/popular in UK and Europe called Plantur 39 – check it out!

  53. Thanks for the question. Alopecia universalis (the form of alopecia areata that affects all hair on the body) is one of the more severe, and tricky, hair loss causes, and you’re right that it’s autoimmune in nature rather than hormonal. In contrast, those with hair loss due to excess DHT tend to have more abundant body hair!

    At this time, the cure for alopecia universalis is steroids, stress reduction, cold laser light therapy, and the off-label use of a rheumatoid arthritis (also an autoimmune condition) medication, Xeljanz. But the efficacy varies…the treatment I’ve reviewed and recommended that is appropriate for the women you know with AA/AU is cold laser therapy, at least when it comes to scalp hair.

  54. Hi Juan, thanks for the question. I haven’t reviewed propecia just yet, primarily because it’s a prescription medicine prescribed to men for hair loss, and my blog targets a female audience. HOWEVER, that doesn’t mean I can’t share my thoughts. Personally, for supplements, I’d recommend Nutrafol for men over propecia because it was designed to have the same benefits (specific to men) without the sexual side effects that so often come along with propecia. Check it out! And if you take a supplement, you really also need to use a hairloss shampoo as well – this one gets you a lot of bang for your buck.

  55. Thanks for the great question. At this time, there’s no P2D2 blocking hair loss treatment, but my guess is that there are many in the works, pending research, development, and approval! Until then, if you are in fact losing hair, definitely get yourself on a good supplement and a caffeine or DHT blocking shampoo like this one!

  56. There’s nothing specific in this shampoo to treat dandruff, so if her dandruff is severe I would recommend a shampoo that targets both the dandruff and hair loss. Great question, thanks for asking!

  57. Hey Joanne! Thanks for stopping by…come back and let me know how the Propidren works for you. Of course, I know all these things have to be evaluated in slow motion because that’s just how the hair rolls. If that fails, then you’ll have to give Nutrafol a shot!

    As for the shampoo – well, if I recall, you have curly hair…is that right? OGX Fight Fallout Plus gives a ton of volume, which may be a good or bad thing for curly hair. My hair is a straight/curly combo (yup: curly on bottom, straight on top) so I like it. Normal size bottles, but under $20 for a shampoo/conditioner set. Hairloss DHT Shampoo gives you the most bang for your buck, because it has a ton of herbal DHT blockers and it’s a huge bottle. You could combine that with rosemary-infused vinegar as your conditioner and that would get you by for months, I’m guessing. Ultrax is still my favorite caffeine shampoo but it’s so flippin expensive!

  58. You can get this shampoo in the uk but have a £15 tax when it arrives,don’t know why that should be makes the shampoo more expensive.still love it after 3 months though.

  59. Hi, thanks for the review. It was helpful. However I am wondering by all the reviews on shampoos when you teach never shampooing your hair at all. You mention many times in your Hair Equilibrium course to throw away all commercial shampoos and shampoo once a week maximum. Do these reviews in fact mean that in your opinion there is a healthy and necessary alternative to harsh shampoos and this shampoo being one of them? Please advise, thank you.
