Nioxin System 3 Shampoo is designed for color-damaged, dry, and brittle hair types, aiming to visibly thicken strands with a blend of biotin and niacinamide. This 300ml shampoo gently cleanses the scalp and hair, removing excess sebum, product build-up, and environmental residues while delivering lightweight hydration. The formula prevents stripping moisture, leaving hair silky-soft with a high-shine finish. It also helps protect and preserve color vibrancy, resulting in fuller, stronger, and less brittle hair when used with the complete System 3 set. The shampoo promotes a healthy scalp environment, making it suitable for daily use. It is part of Nioxin's #1 Professional brand for thicker, fuller hair, built on a legacy of clinically proven solutions that turn scalp science into true scalp care and hair thickening products with proven results.
