Hair Loss Restoration Laboratories DHT Blocking Conditioner: Review

Our good friends over at Hair Loss Restoration Laboratories have just logged a year into research and development for this conditioner.

Why Use a DHT Blocking Conditioner?

This is one more opportunity in your daily routine to douse your follicles with powerful ingredients that block that pesky hormone DHT.

DHT, as you may know, is a testosterone byproduct that is the main cause of hair loss for both men and women.

The Hair Restoration Laboratories’ DHT Blocking Hair Loss Conditioner is specially formulated to work in connection with the DHT Blocking Hair Loss Shampoo.

When used together, this is a powerful shampoo/conditioner combination available to help prevent, halt and reverse hair loss in both men and women.

What’s In This One?

The DHT Blocking Hair Loss Conditioner dramatically helps prevent and reverse hair loss with more clinically-proven DHT blocking ingredients than any other conditioner.

It includes powerful DHT blockers, such as caffeine, saw palmetto, black cumin seed oil, cayenne fruit extract, rosemary leaf oil, pumpkin seed oil, green tea leaf extract and many more.

Clinical studies establish that the ingredients in the DHT Blocking Hair Loss Conditioner effectively block and remove DHT from your scalp (the hormone that causes male and female-pattern hair loss).

The DHT Blocking Hair Loss Conditioner also contains a proprietary blend of extracts, amino acids, oils, antioxidants and nutrients that will deeply condition your hair, nourish hair follicles and encourage healthy hair growth, including safflower seed oil, argan kernel oil, jojoba oil and sweet almond oil.

Additionally, the DHT Blocking Hair Loss Conditioner is loaded with ingredients to significantly improve the strength and thickness of your hair, including hydrolyzed wheat protein, hydrolyzed wheat starch, silk amino acids, panthenol, tyrosine and cystine.

How Do These Ingredients Help With Hair Loss?

Let’s take a look at some of the most prominent ingredients.

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 beneficial properties, which may contribute to reduced hair loss and shinier, more 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 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 B7/H)

The chemical formula of biotin

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 that 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 an intensive hair conditioning vitamin. This ingredient also softens the hair, provides essential healthy-hair nutrients, and soothes and protects the scalp.

Nicotinic Acid/Niacin/Vitamin B3

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 oil increases hair growth and is 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 have established that it promotes 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.  It is a powerful antioxidant that helps protect the scalp and hair from free radical damage.

Polygonum Multiflorum Root Extract

Studies have established 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

Studies have established that rosemary oil can be just as effective as minoxidil and stimulates hair growth.

Cedrus Atlantica Bark oil

Subjects in a control group study massaged with this oil showed an almost 50% improvement in hair loss.

Phyllanthus Emblica

Studies establish that this herb is a potent 5-alpha-reductase inhibitor and hair growth promoter.


Multiple studies confirm that caffeine is a powerful DHT blocker. In a study published in the International Journal of Dermatology, researchers saw in vitro growth inhibition of human hair follicles exposed to testosterone. In the same study, the deleterious effects from testosterone were counteracted by low concentrations of caffeine under the same conditions.

Additionally, and most importantly, caffeine stimulated growth in the cultured hairs in the same study and under the same conditions.

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.

Cayenne Fruit Extract

The most important component in cayenne fruit extract is capsaicin.  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.

How Should I Use DHT Blocking Conditioner?

Following use of a DHT blocking shampoo (it can be any shampoo, but you really should use a DHT blocking first round), apply a generous amount of the Conditioner to your hair and scalp.

Leave the Conditioner on your hair and scalp for a period of 3 to 5 minutes to allow maximum absorption of the hair loss-fighting ingredients. Then, completely rinse the Conditioner from your scalp and hair using cool to warm water.

How Long Will It Take to Work?

Results should be apparent within 3 to 5 months of daily use.

That may sound like a long time, but the cold hard reality is that this hair loss treatment journey takes a long time.

At least these days, we understand some of the science of hair loss and there are many good products out there to help treat it. 100 years ago, our sisters didn’t have these choices.

Overall: Get Some!

One reason I like the Hair Loss Restoration Laboratories products is because they’re such a great value. The bottles are a full 16 ounces, and their base model DHT blocking shampoo clocks in at under $15.

I’m excited to see hair loss treatment people turn their focus on conditioners and conditioning treatments.  It makes sense – almost all of us use conditioner, so why not take that opportunity to saturate our follicles with more of these healing ingredients?

  1. Thanks for this in-depth review, I actually stumbled on it through a simple Google search.
    I have been considering a hair-loss formulation for quite some time, while I am not really going bald, I do have a slight receding hairline that seems to remain the same for many years.

    I notice that you mentioned a shampoo as well, do you have to combine them both to experience the desired effect?

    Also, does this formulation actually successfully regrow a persons hair to their original state, and if so, how long before someone can expect to see results?

    Thanks again!


  2. Hi Mike, thanks for the great questions. First of all: yes, you should use the DHT blocking conditioner along with a DHT blocking shampoo for best results. Secondly, it kind of depends on the cause of your hair loss and how long it’s been going on. If it’s been gone for a long time, and your follicles are totally expired, there’s no bringing it back from the dead. However, if your follicles are just weak and dormant, the answer is YES, you can bring back your hair. If you’ve had the same receded hairline for a good 10 years, keep your expectations low, it’s likely that many of those follicles are dead. Many, but not all – give it a shot!

  3. Interesting. My wife has a thin hair problem. Is that something this product can help with as well? I wouldn’t say she has a hair loss problem. She is always complaining about how thin her hair is. It is quite thin and could use some thickening up. Thanks.

  4. Nice! I love your review of the DHT blocking shampoo so I am so glad to see a conditioner. I usually look for a good conditioner with a detangler. Do you think this conditioner would be able to work as a detangler or can I use one with this?

  5. Yes, products for hair loss can also help for hair thickening -they will strengthen the follicle to grow hair with wider diameter, which means thicker stronger hair. I’d suggest she give these products a few months to see if she notices a difference!

  6. My guess is that if you normally need a detangler with normal conditioner, you’ll need one with this one, too. I’ll come back and let you know after I get my bottle (just ordered!) and update my review. thanks!

  7. Fantastic article! If this conditioner blocks DHT then many people will be happy with a full set of hair! The affordability is great!

    How regularly do you have to use this?


  8. Wow, some great ingredients in there! I need some of this in my life – my hair is pretty thin, not horribly, but def need a boost in thickness and luster. I’ve studied herbalism and familiar with what certain herbs and natural botanical do for skin and hair. I love that this conditioner utilizes many different botanicals, etc to really amp up the process of hair thickness. I’ve tried some chemical laden shampoo conditioner (Nioxin) and that made my hair fall out, not add to. Pretty terrible experience.
    Anyways, thanks for this post!

  9. They recommend daily use. I think using it every other day is probably ok, though – I don’t like to go too crazy washing my hair all the time. thanks for the feedback!

  10. Thanks for sharing your experience with herbalism and the perspective that this one is a keeper! And yeah, I’ve heard Nioxin is bad, I haven’t even bothered reviewing it yet, but I probably should just given how many people write to me complaining about it. thanks for the feedback!

  11. I’ve been researching hair loss for my husband because he has been losing his hair for about 3 months now. I was aware of shampoo that can help with hair loss. However, with the shampoo and conditioner is there a chance that you can overdo it? Meaning, I know it’s supposed to help, but with all the ingredients in both the shampoos and conditioners can’t there be some adverse side effects?

  12. Thank you for the new information on this conditioner. I’m actually very familiar with biotin and when I use it, it makes my hair extremely thick and strong. So I can only imagine it working with these other ingredients. I’ll definitely be checking this out.

  13. these are natural ingredients and things like side effects and reactions are highly individuated – people all have different allergic response potentials and sensitivities. What I can say is I’m someone with a sensitive scalp, and i don’t feel any irritation from the professional strength shampoo. If in the unlikely event I feel it after using it in combination with the conditioner, I will be updating my review for sure! thanks for the thoughtful question, Joan!

  14. Thanks for another in-depth review. What I notice with a lot of these products is the extensive ingredient lists. Do you think it is better to use one with a lot of different ingredients or use several that have fewer ingredients?

  15. I’ve got this hair loss problem, well, who doesn’t. Will definitely check this out along with the shampoo. Your review provides sufficient and additional information for someone helpless when it comes to hair problems, lol. Thanks for this. 🙂

  16. Thank you so much Penelope, this conditioner looks great for hair growth and hair loss prevention. The review is really well explained and the ingredients are the powerhouse for making hair strong. You always share great products for hair growth and hair loss prevention, thank you.

  17. Wow, what could be better for hair loss tan a DHT blocking shampoo? Ever since I learnt from you about DHT (something I’d previously never heard of) Iv’e been convinced that I have a DHT overload, which is something I would like to correct obviously. I was wondering if whilst using these shampoos are there certain dietary things you could be eating that would also help from the inside?
    I love the ingredients list here, as always you have sourced out high quality and natural ingredients which is whet I love about your website.
    I notice this shampoo has Argan oil in it – this is an oil I use to give my damaged and dry hair a deep condition and it works an absolute treat!

  18. This conditioner sounds amazing!
    I had to try over 20 conditioners until i found one that worked, but lately not so much.
    Many leave my hair smooth but dry our my scalp and i hate it….I end up worsening my hair health 🙁
    So I got to give this one a try! And you mentioned you have reviewed their shampoo? I got to check it out, I bet together must work wonders.
    Thanks for another great review Penelope!

  19. Good question – there’s the kitchen sink approach, or the focused approach. I’d say for people with no known allergies, throw the kitchen sink at it! That’s definitely the philosophy behind this brand of products.

  20. I agree, argan oil is amazing and so so hydrating. Thanks for the great feedback, and I’m glad that this site brought you more awareness about the underlying causes of hair loss and some strategies to tackle them.

  21. This shampoo has a nice list of botanical ingredients which I appreciate, although I don’t use shampoo myself but I like natural.
    It’s well priced for those looking for hair loss treatments on a budget too. The only downside I feel is the 14 day money back guarantee. If it takes months to see results this guarantee doesn’t really stand up. However, for the price and with the discount code it sounds like it’s worth a try!

  22. Oooo, tell me more about how you don’t use shampoo. Do you use the no-poo method? I’m torn because I like doing no-poo but I also don’t know a good way to get all this good stuff in contact with my hair and scalp without using traditional shampoo and conditioner products…and because of my hair loss, I need these DHT blockers.

  23. What amazing, healthy ingredients for hair. I can’t believe how many -healthy- products there are now for hair loss. I had a complete hysterectomy when I was 29, so of course, most of my hair fell out when I “lost” all of my hormones. The ladies version of Rogaine helped a little, but I didn’t like using those chemicals. Anywho, not sure what shifted, but my hair finally grew back in thicker with more body and a little curl/wave to it. If I start to lose it again, I’ll be sure to buy some of the products on your site. They all look like they would work really well!

  24. great article i didnt realize there were so many options to stimulate hair regeneration. can these be used by men as well or is there differences in what causes hair loss and regeneration from a chemical standpoint for men and women

  25. Hi, I have been using Ultrax Labs Hair Surge for about a year now and have not really seen any progress so I was looking for an alternative. Have you heard of Ultrax Labs and do you know if it is any good?

  26. Hi Penny,

    Great post. My hair is a little too far gone now in fact I even shave it and like it. I live in a warm climate so good to not have much hair here Haha! The shampoo sounds pretty amazing though. You really give a thorough review.

    Are the products all natural? No hidden toxins anywhere? My brother is really concerned about his hair and its slowly melting away haha. I will let him know about this for sure. Thanks for another interesting and thought provoking post.


  27. I learn so much from your reviews. I like how you pay attention to how the ingredients help with hair loss and actually explain what they are and what their purpose is. This conditioner seems to have all the right ingredients to prevent hair loss and is worth a try.
    One thing that I can’t figure out yet for myself is the amount of time you have to wash your hair. You mention a daily use of the conditioner. I wash my hair once a week mainly because I have straightened hair (previously natural hair) and washing it daily would mean using the drying and iron daily which is not good for my hair. But I feel as if maybe I am missing out?

  28. This DHT blocking conditioner is really effective and great as one of my friends used it and find it really helpful and her hair grows really fast, now I am thinking to use it as well. Very effective and one of the best product, everyone should try it for their hair growth.

  29. This hair conditioner looks amazing and I am sure it is very very effective as I have used many products as per your recommendations Penelope and I am really happy with every thing. Thank you so much Penelope for sharing such useful products and tips with us.

  30. Thanks for sharing your thoughts, Annette! I agree, it’s so tough to find a good conditioner, one that leaves hair lustrous without being greasy. And yes, definitely pair it with the shampoo.

  31. thanks for sharing your experience – and it’s a great topic for sure. women so often experience hair loss after hysterectomies. I’m glad to hear that you had some solid regrowth after awhile! If your hair ever does start falling out again, consider nipping it in the bud right away with DHT Blocking products like these, and a high quality hair loss supplement. thanks for reading!

  32. Hi Garry, thanks for the question. There are some differences in hair loss causes between men and women, but one big similarity, and what this product targets, is the main cause: excessive DHT on our scalps. DHT is a hormonal byproduct of testosterone that blocks our androgen receptors in our hair follicles, stunting them. Unfortunately it’s just as problematic for women and men…and this conditioner, and other products by these people, are unisex, effective for both men and women.

  33. Hi Amanda, I’m sorry to hear you had no luck with Ultrax- it’s one of my favorites …but pricey. Why don’t you go ahead and try a less expensive but effective alternative, the shampoo from Hair Loss Restoration Laboratories.

  34. IN terms of ‘toxins’ – this is a more conventional product with botanical additions, meaning it contains some ingredients that bother people, like SLS. If you’re looking for something totally natural and organic, I’d advise your brother to consider Phytoworx – that stuff is totally legit & all-natural.

  35. It depends on how much moisture your hair could tolerate between washings – you can always use a great topical treatment overnight instead of the frequent washings. I leave my DHT blocking shampoo and conditioner in 4-5 minutes each…long showers, I know! thanks so much for the kind words, and thanks for reading!!
