Ideal for damaged hair types, the Nioxin System 4 Scalp + Hair Conditioner helps to strengthen the feeling of hair prone to breakage and snapping. The hydrating formula nourishes the scalp to promote optimal conditions for future hair growth. Infused with a biotin blend, the conditioner helps to visibly strengthen brittle, weak strands. Niacinamide intensely nourishes lengths while helping to minimise visible breakage to reduce hair fall. The colour-safe formula promotes fuller, thicker-looking hair when paired with the rest of the System 4 collection.
