The System 1 Scalp + Hair Shampoo does much more than simply cleanse. Formulated by Nioxin, the shampoo lathers over the scalp to remove impurities and excess oil, while creating the optimal scalp environment to promote new growth for visibly thicker, stronger and more resilient-looking hair. A blend of niacinamide and biotin helps to give fine hair extra volume for a plumper-looking, more voluptuous finish. Follow with the System 1 Conditioner and Treatment for optimal results.
