This pre-shampoo Color Locker has an exceptional anti-color-stripping action. Its unique gel-oil formula instantly penetrates the hair fiber to lock down the cuticle while protecting the hair fiber to its core. It forms a protective barrier around the hair to trap pigments within the hair cortex and prevents it from washing out. Perfectly protected at each shampoo, hair color maintains its vibrancy and lasts longer.
Before shampooing, apply to dry hair, from roots to tips, one section at a time. Leave on for 1 to 2 minutes. Rinse, then shampoo hair with the PHYTOMILLESIME Shampoo, followed by PHYTOMILLESIME Color-Enhancing Mask. May be used up to 3x a week.
