Nioxin Shampoo System for Thinning Hair

In my 20 years of researching hair loss, around a dozen brands of products have garnered massive publicity. Among the few of these that I have yet to review is the Nioxin line of shampoos and system kits. Also see my posts on Revivogen and Nizoral for other highly popular shampoos.

The Nioxin system kits include a shampoo, a conditioner and  a scalp treatment lotion for thinning hair. All of these are used by men and women, for both pattern hair loss and generalized thinning. Nioxin is owned by Proctor & Gamble. Make sure to check out the company’s Instagram.

Nioxin Shampoo Recommended by Alyssa Milano

Alyssa Milano was in the news last year due to her major hair loss and shedding due to Covid-19. Last month, she said that her hair regrowth was aided by Nutrafol supplements and Nioxin shampoo and conditioner.

Yesterday, a Yahoo headline mentioned that Alyssa Milano’s favorite Nioxin shampoo was on sale for 64 percent off on Amazon.

Only Nioxin 1 (for light thinning of natural hair) seems to be that steeply discounted (current price of $15.66). Nioxin 2 for progressed thinning is a bit more expensive. The combined Nioxin line of shampoos currently have almost 15,000 reviews on Amazon, averaging a stellar 4.7 out of 5 stars rating. Note that the cleanser shampoo systems 3-6 are for colored and bleached hair types.

Even more impressive, the system kits have a combined 22,800 reviews on Amazon. At an average rating of 4.4 stars out of 5, this is pretty impressive for a shampoo and conditioner related hair loss product. Of course Amazon has a huge problem of fake reviews, so it is also good to check customer opinions on other sites selling Nioxin. The most popular of these include Wal Mart, Costco and Walgreens.

Nioxin Ingredients

Nioxin contains ensulizole, sulisobenzone, nettle root extract, niacin, biotin, numerous other B vitamins, and saw palmetto. The last mentioned is a leading natural dihydrotestosterone (DHT) inhibitor to reverse androgenetic alopecia. Also included are salicylic acid, peppermint oil and menthol. Most of these ingredients are unlikely to cause any significant side effects.

According to the company’s website:

“The Nioxin Cleanser Shampoo removes dirt, excessive oil and other environmental residues from the scalp and hair. “

Ultimately, this reduces hair shedding and supposedly makes existing hair thicker. Note that even the best dermatologist recommended hair loss shampoos will not regrow hair on totally bald areas of the scalp. In a majority of cases, the product marketing overpromises on results.

Newer Products

Apparently, Nioxin now also offers hair care products that contain Minoxidil 2% (for women) and the unique Sandalore. The company is devoting significant resources for product innovation. Hopefully they can even include ingredients such as Stemoxydine and Resveratrol in their products going forward.
