The Nioxin Scalp + Hair Thickening Trial Kit (System 3) is specially formulated for dry-damaged, coloured hair with light thinning, offering a complete three-step regimen to promote thicker, fuller hair. This trial kit includes the Scalp + Hair Shampoo, Scalp + Hair Conditioner, and Scalp Care + Hair Thickening Leave-On Treatment, all designed to nourish, strengthen, and protect the hair and scalp.

The Scalp + Hair Shampoo gently cleanses, removing follicle-clogging sebum and environmental residues while preparing the scalp for optimal hair growth. The Scalp + Hair Conditioner hydrates and strengthens, improving hair resilience and reducing breakage. Finally, the Scalp Care + Hair Thickening Leave-On Treatment stimulates hair follicles, promotes hair density, and adds volume and shine, completing the three-step process for fuller-looking hair. This trial kit is perfect for those looking to address light thinning while improving scalp health and hair strength.
