Hair Restoration Laboratories Review – DHT Blocking Shampoo?


Hey girls! It's Monday which means a new post. Today I am going to be reviewing Hair Restoration Laboratories. Back when I was going through my Hair Loss issues, this DHT Blocking Shampoo from Restoration Laboratories wasn't the first shampoo I tried. It took a couple of months before If I recall correctly, stumbled upon a YouTube video reviewing it.

Hair Restoration Laboratories LLC, a company from Voorhees TownshipNew Jersey, are the people behind it. On their website for sale, they currently have "Ultra Strength Hair Regrowth Treatment", "Hair Restore Shampoo & Conditioner Set", "Professional Strength Hair Restore Shampoo", "Hair Restore Conditioner" and finally the product I bought and tried. Hair Restore Shampoo.

Today I will just be going over their products that have the DHT Blockers and no the other ones that use Minoxidil. Their products are of course suitable for both men and women, but this review will come from my experiences.

How the Shampoo & Conditioner Works

I had no idea what Dihydrotestosterone (DHT) was back at the start of my journey, and I still don't....

Only Joking!! I understand the basics now. DHT is one of the main reasons a woman might start losing her hair. Let me explain.

Everyday 10% of a women's testosterone is converted into DHT via the ovaries and skin. It is the cause of the first pubic hair growth in a girl during puberty. If an adult woman has too much Testosterone converted to DHT, then this will hurt the hair follicles, and thus hair loss can become an unfortunate factor.

You might be wondering why your producing too much Testosterone but the fact is for most girls they are just genetically more prone and it's not a result of lifestyle decisions. The process is way more technical than I described, but that is the basics of female hair loss from DHT.

Customer Reviews


When you visit their product pages you will notice the 5 star reviews. It is extremely easy fake these though so I don't trust them. They also have Google Reviews but again I don't trust them. 

Thankfully they have products listen on Amazon. I trust the reviews there because they are much harder to fake. They have 3.7 out of 5 rating and to their credit the reviews are pretty good.


There was one negative review there but you should know that their products won't work for every single person. If your Hair Loss isn't caused by DHT then it probably won't work

Hair Restoration Laboratories Ingredients

Just like in my first review I am going to look at all of the individual ingredients inside this shampoo and see if I can find anything interesting. Although there is over 30 ingredients, I am just going to cover the 15 that I think are most important. The other ingredients I am not covering are all free of parabens, sulfates, phthalates, silicone, & harsh chemicals. I will be using this resource to check if the ingredients can inhibit DHT growth.

1) Argania Spinosa Kernel Argan oil

This is a fruit and provides the Argan Oil which of course is great for hair (1). Argan Oil has Oleic Acid & Linoleic Acid which can block DHT growth (2).

2) Tocopherol (Vitamin E)

Diets with a consumption of Vitamin E have shown to decrease the risk of various cancers (3). For hair it doesn't block DHT but does have anti-inflammatory effects (4) which can help with hair loss if that is your cause.

3) Camellia Japonica Seed Oil

I know that this oil from Japan has benefits as an Antioxidant but I couldn't find any studies on it's impact on DHT Blocking. Camellia oil does however provide Palmitic and Omega-6 Linoleic fatty acids which are a nice moisturizer of the skin & hair (5).

4) Soy Isoflavones

This is an interesting ingredient since Soy foods contain Isoflavones which mimic estrogen. Higher estrogen and lower Testosterone can inhibit DHT (6.) Soy Bean Oil also contains Linoleic Acid which is a great DHT blocker (7).

5) Rosemarinus Officinalis Leaf Oil

Rosemary Oil is one of the best natural blockers of DHT oil out there and there was a powerful study done on mice that proved it (8).

6) Astragalus Membranaceus Root Extract

Doesn't block DHT but is great for hair growth since it contains polysaccharides (9). fights inflammation, and contains fatty acids which as mentioned previously helps as a moisturizer.

7) Polygonum Multiflorum Root Extract

There are solid well conductied studies out there that show Polygonum Multifolorum Root is beneficial for hair growth using the dermal papilla cells (10).

8) Nicotinic Acid/Niacin

There was excellent piece of research done (11) that showed it's effects on the hair. It doesn't appear to block DHT but can help with inflammation on the scalp.

9) Citrus Medica Limonum Oil

Not a DHT inhibitor and not a lot of research for hair care. It is rich in Vitamin C though which helps with collagen and that is beneficial for hair growth (12).

10) Salvia Miltiorrhiza Root Extract

I read a post that said for hair growth the follicles should receive highly oxygenated blood and it said this extract does whole lot of positive things for blood. According to another well done study it showed it had no effect on blood pressure (13).

11) Biotin (Vitamin H)

Vitamin H has no effect on DHT but I know it does promote hair growth based on a study done on women with thinning hair (14). It is worth noting though that the Vitamin H was taken as an oral supplement.

12) Hibiscus Rosa-sinensis Extract

Interesting study done on albino rats that did show more potency hair growth over the course of a 30 day trial (15).

13) β-sitosterol

Beta-Sitosterol is perhaps the most beneficial and interesting ingredient. It has the ability to stop Testosterone from converting into DHT which has been confirmed scientifically (16). 

14) Ligusticum Chuanxiong Root Extract

I can't find any good information on this ingredient for hair growth. Some people believe it helps wit hair loss but I can't back that up. 

15) Nigella Sativa Oil (Black seed oil)

OMG FINALLY! The last ingredient. Black Seed Oil has shown to benefit the hair for growth but not by blocking DHT (17).

My Experience With Hair Restoration Laboratories


I decided to order the Shampoo & Conditioner Set which is currently priced at $39.99. It took about 1 week to arrive to my address and everything was sealed nicely. I opened the box straight away and since it was the morning I decided to hop in the shower and use the products right there and then. 

DHT Blocking Hair Loss Shampoo boasts of good thickness and lather, and it didn't not tingle or burn when leaving it on my scalp for the recommended three to five minutes.

Through my trials of hair loss treatment and usage of DHT blockers, I have finally realized that DHT is without doubt the main nasty reason behind the majority of hair loss and that was the case for me! It only took me 6 months and hundreds of dollars wasted to find out lol.

I think that it is far better to use something containing DHT blockers rather than use something containing nothing. This is why I would endorse others to use this shampoo, particularly for individuals on a tight budget who would never be able to afford its super expensive mainstream counterparts.

This bottle of shampoo will last 2 to 4 months, depending on the length of your hair, giving you even more value. I used it on my extremely long hair, and one bottle lasted nearly two months.

This excellent hair loss treatment is the best option for people on a tight budget. Some other similar shampoos cost in excess of $50 for a much smaller bottle, which can put people off, especially those on a tight budget, to the extent that they do not opt for any treatment which is sad imo.

The icing on the cake is that you get a huge bottle for the price. Most other shampoo bottles are available in the 8-10 ounce range instead of 16 ounces.

Final Thoughts & Coupon Code
