PRODUCT DETAILS

Bring the salon home with this advanced acid and heat care shampoo, designed to repair seriously damaged hair at the structural level. The acid formula works to realign damaged proteins in the hair shaft — the same principle used in professional salon treatments — restoring smoothness and reducing frizz with regular use. Premium Keratin and Silk proteins fill in hair porosity, improving elasticity and shine, while a heat-care complex protects against damage from hairdryers and styling tools. Infused with rare botanicals including Haberlea Rhodopensis, beet root extract, and mandarin orange peel extract for genuine repair from root to tip. Best paired with the matching Truest by S FREE Treatment.
