Though our shampoos are generally formulated with ingredients that keep hair from feeling dry, our growing number of chemically treated clients - a group that's sensitive to moisture loss - made what used to be a gap in our cleanser range quite obvious. We introduced Gentle Shampoo especially for the chemically addicted (and chances are, chronically parched). Its luxurious feel and fragrance quickly made it a favorite among the general population, and our best-selling shampoo.
