NIOXINSystem 4 Scalp + Hair Thickening Shampoo for Colored, Dry, & Damaged Hair with Progressed Thinning | Maintain Vibrant Color | Cleanse, Nourish & Boost Hair Density with Niacinamide & Biotin

My spouse has a bald spot. it appears this helped. I watched as tiny thin hairs filled up the silky shiny spot and lite regrowth happened. I watched daily as thin sprouts became longer thin sprouts. If you ever had a part in your hair and followed it to point where it would end at back of scalp top...that's the spot I'm talking about. Rogaine does one area. Other products do other areas. This one got the spot in-between I hadn't seen advertised. don't know if it works for your head, but maybe they have the something that cleans those pores enough to allow sprouts to appear. Hair loss is hard on people, but it was lite weight and cleaning and seemed good quality. I have thinning hair but haven't tried it yet as a woman as didn't want to take his shampoo from him. I have no stories from woman point a view. Only from view above...looking at my man's bald spot and watching him feel more excited at new growth. Which is what we want in a great product.

My hair feels and looks thicker and shinier and less of it is in my brush every time I use it. have thinning flyaway gray hair (thyroid disease) and I swim laps 3-5 times a week so the chlorine doesn’t help. When I wash my hair with this shampoo it is squeaky clean - it gets out all the chlorine and product. It sudses well and rinses well. I don’t care for the smell but it doesn’t linger in my hair so i can live with it.

The media could not be loaded. This shampoo was recommended to me by my dermatologist to help with hair shedding. I have tried quite a few shampoos, and this is the one I find myself going back to. It really does reduce shedding for me. I have an oily scalp and wash my hair every day and have seen the benefits. It cleans just enough, reduces shedding and adds shine. I'm not sure how it would do for those with a dry scalp, however.

This is my go-to shampoo. My hair and scalp are healthy and my hair is thick, full and shiny. Great value, Love it!

Seems to be helping. I had a great deal of hair loss due to stress. This has been helpful. It’s been about 6-7 months and I’ve got a lot of new growth. It’s definitely noticeable at my hairline above my temples that it’s filled in. It’s very expensive though.

I’ve been using the Nioxin System 4 Conditioner (paired with the matching shampoo) for a few weeks now, and the difference is impressive. My hair is color‑treated and has been thinning for a while—this lightly moisturizing formula feels gentle yet powerful. It leaves my hair feeling soft and manageable, without any heaviness or greasiness.The texture is lightweight, yet hydrating—from scalp to ends. It’s formulated with peppermint and wild mint oils that invigorate the scalp, while caffeine, niacinamide, and biotin help strengthen hair at the root and promote a healthier scalp environment.Since using it regularly, I've noticed less shed during brushing and shower drain buildup, which used to clog weekly—now it's only occasional. My hair feels thicker and fuller overall, although I didn’t expect a dramatic regrowth—more like restoration.It helped stop the progression of hair loss; not necessarily added growth.

Excelente producto.

A little if this is all you need for tons of lather. Will take time to see if it helps with hair loss but it sure gets hair squeaky clean even in soft water. Rinses out fast. Smells great.
