Add body to thinning hair with Nioxin’s 3-part System 6 Shampoo for Chemically Treated Hair. The derma-purifying cleanser deeply cleans the scalp, encouraging the appearance of fuller-looking tresses. Infused with glycol-shield 2.0 technology, the treatment aims to improve the appearance of excess oil and residue. Formulated for colour-treated, thinning hair, the shampoo is enriched with peppermint oil to refresh the scalp. The cleanser is the first step in a three-part hair treatment, designed to strengthen the hair’s natural structure and promote the appearance of thicker strands.
