I just discovered Generic Value Products from Sally Beauty. I purchased the GVP Volumizing Shampoo, Conditioner and Volumizing Root Lifter all compared to the Matrix Amplify Volumizing System. The ingredients are the same at about half the price! They have a sale right now, buy 2 get 1 free. They work so great!!! I have really fine hair and can't believe the difference they make.
Sorry if I sound like an advertisement but I just wanted to share.
