The Nioxin System 4 Scalp Treatment seeks to thicken the appearance of thinning, damaged hair with a stronger-looking finish. Boasting a lightweight serum texture, the formula applies to a dry, clean scalp as an everyday treatment. Infused with niacinamide, the formula works to nourish the scalp to promote optimal conditions for future hair growth. Biotin enhances the formula to reduce the risk of potential breakage and hair fall. The colour-safe formula works best when paired with the rest of the System 4 collection.
