Color Therapy is a 5-minute color-depositing hair mask that conditions and strengthens hair. Powered by positively charged SmartDye™ Technology, the restorative treatment deposits color where hair needs it most. Formulated free of ammonia, parabens, resorcinol, PPD, phthalates, gluten, SLS and titanium dioxide, and containing nutrients like argan oil, keratin and ginseng root extract, Color Therapy leaves hair soft, hydrated and healthy-looking. It comes in 4 multi-tonal, deeply saturated shades designed to refresh faded color, reduce brassiness and add brilliant shine. Use this in-shower treatment every second or third shampoo in place of your conditioner to infuse your hair with rich, natural-looking color and intense hydration.
