Nioxin Age Defense Serum is a lightweight, leave‑on scalp treatment designed to support youthful‑looking hair by addressing early greying, thinning and loss of vitality. Formulated to revitalise the scalp, the serum helps maintain hair fullness, smoothness and natural colour while improving overall scalp condition. When used as part of the Nioxin Age Defense range, it supports a complete, science‑led routine for stronger, healthier‑looking hair over time.
Infused with Black Oat Peptides, Niacinamide and Caffeine, the serum helps support melanin production, maintain scalp vitality and promote youthful vibrancy at the root. Suitable for daily use, it absorbs easily without residue and is safe for colour‑treated hair.
