Review: It is What It Is!!! And that is a GREAT SHAMPOO! - I have used Nioxin Cleanser, System 1 (which is for fine/Untreated/Normal to Thin hair). My hair is "untreated". I have always had baby fine hair. Also, my hair is on the oily side and anything will make it bog down and oily. This product does not make my hair do either of these two things. With my hair being untreated, I have always relied on "product" and Velcro rollers for uplift (I am very careful about taking the Velcro rollers out of my hair due to breakage). Unfortunately as a lot of women get older their hair gets thinner. I happen to fall into that category. Also I WAS having problems with it breaking off. I discovered this shampoo about six years ago. I used it steady for about three years. My hair quit breaking off and it looked and felt SO much healthier. I stopped using it for a few months thinking..."I will just buy OTC shampoo for a while". BIG MISTAKE!!!.... The next trip to my hairdresser she said that my hair was breaking off. She even asked if I was doing something different to my hair. I told her that I had stopped using my regular shampoo and I proceeded to tell her the name of it. She started raving about how good of a product it was. So I came home and ordered another bottle. I always order the 33.8 ounce and it lasts me for months. I mean like 6 months. And all you have to use is a dime size. I also am a everyday shampoo'er. Although I do not find that this is by no means a product that promises to make hair thicker... It does help with the over all problems for what it says... "Fine/untreated/normal to Thin hair"... I only have tried the Shampoo. I have not tried the other products that you can use with it... which is why the word "system" is in the name.....BUT! I am going to try in the near future. And when I do I will give an update on my review. Also, this shampoo has a peppermint / menthol feel to it on your scalp (only while you are soaped up. Not after you rinse). It also has a very pleasant smell. So bottom line...It is what it is and that is a GREAT SHAMPOO!!! UPDATE... they changed the formula it now makes my head itch. Just as well buy OTC shampoo for the same effect. Very Very sad because I have been using this product for years.
Review: Great shampoo! Please read this! - This is an excellent shampoo. It's expensive, but it does an excellent job. I've been using it for years. What it will not do: -Grow your hair back. -Stop your hair from falling out. It 'may' possibly slow hair loss. I'm skeptical on this though. What it will do: -Add volume to your hair -Get your hair clean, really clean -Does not seem to damage hair I have some hair loss, but I didn't buy this to solve that problem. I really don't care about that. In my search for quality products, my search stopped here. It gets your hair clean without drying it out like cheap shampoos do. It will restore volume to your hair as opposed to flat, boring hair. And it works if you have bad/hard water. While it is expensive, it doesn't take much and will last a long time. The ultimate test was my mother (>70 yrs). Her hair has been looking like a trampled mat for the last few years. I asked her to try it. She did and it worked wonders. TL;DR - This won't grow your hair back, but it's a damn good shampoo.

## Questions & Answers

**Q: why has the formula changed..new formula not getting good reviews**
A: Hey P&G, I see you are answering new questions now.  Would you please answer this question above.  This seems to be the most concerning to users.
Why has the formula changed..new formula is not getting good reviews?

**Q: has the formula been changed?**
A: This product used to help my thinning hair prob.
Now, Oct. 2022, it seems to be exacerbating the problem.  
Irritating my scalp, excessive dryness, . . . 
Very harsh!
I hate to dump this into my septic tank but need to dispose of it some way.
The color of the shampoo has changed so obviously the formula has changed.
Wish I had stopped using it sooner and hope I can fix the damage caused my this “new” Nioxin.
Would not recommend to anyone.  Unless hair loss is the goal.

**Q: Is it true that the formula has changed?**
A: My hairdresser just told me about Nioxin today, so I came online to search for it. After reading reviews here on Amazon about a change from the original product I did a search and it appears that P&G has changed not only the shampoo and conditioner formula, but the supplements that everyone LOVED! Unfortunate for me because I will not pay $200 for supplements that have been reformulated from a formula that worked. Here is a blog I found about it: http://mzmahoganychic.com/2012/05/10/nioxindisappearance/

**Q: How often do you use the shampoo?**
A: I use it once every day from last 3 yearsMy hair stopped falling since I started using Nioxin Shampoo

### ⭐⭐⭐⭐⭐ Saved my hair !
*by M***A on February 15, 2026*

This shampoo has saved me from being bold. My hair lost half its volume in a month and after using this shampoo I notice immediate improvement. My hair started to shed less. I also took Vitamin D3 and hair growth vitamin while using this product.
