Less hair fall
I'm very skeptical when it comes to products that claim to help with hair loss so I wasn't expecting this product to actually help, but it did within two weeks of usage. My hair was falling out in huge chunks due to high stress prior to switching to this system. Only problem is I don't see any baby ...

Good system but not seeing results
I have thick wavy/curly islander hair but I've noticed it thinning the past few years. I've used Nioxin for about 2 months now, the shampoo, conditioner, and the leave in treatment (System 4) and I honestly haven't seen any new growth... or thicker hair.

helped stopped hair loss after 3 weeks
if you have hair loss, just get the progressed option. i use it daily, with extra conditioner and leave in longer so less dry. i also pat in body creamer that makes it easier to comb wet and dry less frizzy. when i am uber stressed or have surgery, i lose hair. stress is easier to manage the loss. im sure not the same for all, but it works for me. i also have very sensitive skin and this did not cause rashes. folks you cannot expect a couple shampoos to turn things around, give it a month. and it is known that at first you might lose more hair, that hair was damaged already and sign system trying do its job.
I would buy again

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.
