Product Details

Nioxin Scalp + Hair Thickening System 4 Shampoo:

Nioxin Scalp + Hair Thickening System 4 Shampoo is a gentle cleanser that removes sebum, residue and DHT at the scalp level. Infused with peppermint oils, niacinamide and biotin, it purifies, invigorates and prepares hair for thickening. Clinically proven to add density and protect colour, it leaves hair feeling refreshed, volumised and strengthened against breakage.

Nioxin Scalp + Hair Thickening System 4 Conditioner:

This rich conditioner hydrates and detangles dry, coloured hair, while reinforcing strand strength to reduce breakage. Enriched with niacinamide, biotin and caffeine, it helps to protect hair fibre, maintain scalp moisture balance and prolong colour vibrancy, leaving hair smooth, soft and visibly fuller.

Nioxin Scalp + Hair Thickening System 4 Leave on Treatment:

The concentrated leave-on treatment delivers antioxidants, botanical extracts and Thio-PGA complex directly to the scalp. Designed to nourish the hair root, stimulate follicles and support scalp health, it promotes thicker-looking hair and boosts volume. Lightweight and non-greasy, it absorbs quickly, refreshing the scalp and strengthening each strand.
