Moroccanoil Blonde Perfecting Purple Shampoo combats brassiness in blonde, lightened, or gray hair. Violet pigments counteract harsh yellow and orange tones, restoring color to its intended appearance. ArganID technology helps infuse Argan oil into the hair’s cortex, helping to repair and seal the cuticle. 92% of consumers reported this shampoo tones down brassiness (in an independent study on consumers ages 18–65, after 1 application). Color-safe, sulfate-free formula helps repair and seal the cuticle with ArganID technology.
