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

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

Excelente producto.

I love this shampo. I noticed new hair growth at the sides of my head within a month. I never go without it, Ever!

The Nioxin shampoo is great, we have used it for years. Worth the money. The problem I'm having is the shipping. This is the second time I have placed this particular order, first time the box was busted and the shampoo missing, was a hassle to get gift card from Amazon to cover cost. Now I've re-ordered, and the shipment keeps getting delayed. NOT HAPPY at all!! Will be a total of about 3 weeks to get a bottle of shampoo!! Not good service.

I just started using this shampoo for hair thinning.,so I can't really say it has worked for that yet. It keeps my hair clean and full. We shall see.

Been using Nioxin for a while. Love it!

Wish I’d found this years ago- FAB
