Good shampoo post chemo + for arid climates
My friend’s oncology nurse recommended this shampoo to her after she finished chemo sbd her hair started growing back. (She’s in remission, yay!) Anyway I was staying with my friend on a visit sbd used some and liked it. I bought a bottle of my own, and it’s been great for my hair. I live in the desert SW and the climate here makes by fine hair so dry and brittle - but this shampoo really helps keep my hair soft and fuller looking

Impressed with the Thickness and Fullness Results
I’ve been using Nioxin System 4 for a few months and I’m really impressed. My color-treated hair is usually dry and fragile, but this shampoo has helped it feel thicker and fuller without weighing it down. I’ve noticed less breakage and shedding, and my scalp feels much cleaner and healthier. It lathers well, rinses clean, and doesn’t strip my color. My hair looks denser and has more body, especially at the roots. If you have dry, damaged, or thinning color-treated hair, this is definitely worth trying.

Good shampoo
My scalp feels very clean when using this shampoo,hair feels dry during shower but as long as i use conditioner, it’s good. I noticed less hair falling after shower

Totally worth it!
Love this stuff! Makes my head tingle with the peppermint ingredient and smells fantastic! Leaves my head feeling fresh and clean! I have dark brown hair that I have to color my grey out….It doesn’t strip the color from my hair & keeps the color longer than other shampoos without fading it. It also helps keep my hair stronger and thicker also than other shampoos without an huge price.

If your shiny bald head needs hair growth...consider this product
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.

perfect
It performs its function as a cleansing and detoxifying shampoo very well; furthermore—and most importantly—it curbs hair loss. The price and quantity are perfectly balanced.

Excelente producto
Es una botella más grande que la que viene en el kit lo cual me sorprendió porque pensé que sería algo similar. Llevo meses usando el producto y mi cabello dura más tiempo limpio. El cuerpo cabelludo se siente bien lavado y no grasoso.
