Nioxin Scalp and Hair Thickening System 4 Leave on Treatment 100ml

The Nioxin System 4 Scalp Treatment helps improve the look of thinning, damaged hair, leaving it with a fuller, stronger-looking finish. Its lightweight serum texture is designed for daily use on a clean, dry scalp.

Powered by niacinamide, the formula nourishes the scalp to support an optimal environment for healthy hair growth. Biotin further reinforces the hair to help minimise breakage and hair fall. For best results, use alongside the complete System 4 regimen.
