I have very thin, limp hair and must use a lot of volumizers and gels to get some lift and control of my hair. This leads to build-up on my hair which sometimes brings on blemishes on my head. I also highlight my hair as I have found that give me some volume. So the Neutrogena Anti-Residue Permed/Color Treated Shampoo is great for me. I have always loved Neutrogena products and this one is no disappointment. If your hair is delicate because of being permed or color treated, or is simply thin and limp, you must try this product.
