RŌZ Foundation Mask delivers deeply reparative treatment for damaged hair. Clinically proven to reduce breakage, this silicone-free formula locks in moisture while improving elasticity. It contains a blend of vitamin E-rich oils, rice bran extract, and rosemary leaf extract to support overall hair and scalp health. After shampooing, combing it through wet hair from root to tip, leaving it on for a few minutes before rinsing gives lustrous, silky results. Each mask includes a custom engraved RŌZ key.
