Wonderful Shampoo
Hair Type Wavy Hair
I've had a great experience with the Nioxin Scalp + Hair Thickening Shampoo. It leaves my scalp feeling clean and refreshed, and my hair looks fuller with more volume. It doesn't weigh my fine hair down and makes it easier to style. This is a great shampoo for anyone with thinning or fine hair who wants healthier, thicker-looking hair.
Lost hair, dried out, red rash
I wanted this to work. My hair dried out and became brittle. My scalp was very irritated and red. Then I lost a bunch of hair. I contacted the manufacturer and they sent me a form, which I filled out and never heard from them again.
