Nioxin System 2 Cleanser Shampoo, 33.8 oz

I've used this shampoo for about a year now and I won't buy anything else. I have very oily hair and this cleans so well that I wash my hair every 2 days. Another thing I noticed is hair growth. It's not a huge growth, but I have extremely thinning hair since I am a diabetic. You can actually feel your hair squeeking clean as you rinse it out. It's pricey but worth it to me. I love the conditioner as well, but don't use it often as I don't want it to make my hair too oily. I don't buy the foam because it sticks to my hair after I blow dry it and makes my hair look greasy. So all I like is the shampoo and the conditioner.
