Revitalizing Shampoo—step 1 in the FNS system—is an anti-aging formula that gently cleanses and nourishes thinning, fine or weak hair. This mild formula was designed without sodium lauryl sulfates, which dry and irritate hair and scalp. It thoroughly removes sebum buildup, clears the follicle pathways and prepares the scalp to receive the optimal benefits from Follicle Nutrient Serum. Essential vitamins, minerals and botanicals promote thicker, healthier hair with strength, body and shine. 6.8 oz. By Osmotics Cosmeceuticals.
