Nioxin Scalp & Hair Leave-In Treatement System 4 200 Ml
I have been using System 3 but thought I'd try 4 instead. After applying this product to my scalp I could not even comb or brush through my hair! My hair is not very thin just a little thin on the top since I'm getting older. Not the same application top at system 3 either. I am sending it back.
Groupon has this great product at an amazing price! If you use Nioxin shampoo and conditioner this product is the next step you need. The system has helped my thinning hair. I've been using it for a year.
