Thinning, fine hair needs a special shampoo. Hair that is thin and weak has low resistance to harsh cleansers, but unless properly cleansed well, scalp oils weigh thin hair down and make lasting volume a challenge. This sulfate-free Scalp Stimulating Shampoo is designed especially for thinning hair to gently deep clean and stimulate the scalp to nourish and rejuvenate the hair follicles. Fortified with keratin and panthenol (pro vitamin B5), hair feels lighter, cleaner, and more buoyant. Leaves hair ultra-clean as it helps clear away impurities at the follicle to improve the effectiveness of scalp treatments.
