I have used Nioxin products ever since going through radiation for a brain tumor and losing patches of hair where the radiation beams entered my head. I now have my hair back, thicker than ever! I owe it all to Nioxin Shampoo, Conditioner and Scalp Treatment. I used to buy it through the salon where I get my hair done, but this price is about 1/3 less. Totally recommend!
I preferred the shampoo in System 2 it cleaned my hair and left it looking fabulous. The shampoo in this system is a little different and I dont think it worked as well for my hair. The conditioner in system 3 was a bit more moisturizing than system 2, but if I left it on for more than a minute it would start to burn my scalp, while system 2 didnt seem to stimulate scalp enough. My hair loss has reduced and hair growth has accelerated with both systems 2 and 3. Overall quite happy!
