The Nioxin Pro Clinical Age Defense Conditioner 240ml is a lightweight conditioning treatment created to nourish hair that feels drier, finer or more fragile over time. Designed to smooth and soften, the formula leaves lengths feeling softer, more manageable and hydrated from root to tip. The formula is infused with hyaluronic acid, niacinamide and caffeine to boost moisture in both the scalp and hair, helping strands feel more supple with continued use.
