This non-stripping, color safe shampoo gently removes 3 big causes of buildup: product, hard water and pollution. The innovative cream-to-lather formula means you can fully cleanse your hair without leaving it feeling stripped. The highly charged anionic polymer helps pull product buildup from your hair, while the chelating agent binds to the metal ions in hard water and removes them from your hair. Gentle but super-efficient, sulfate-free surfactants remove pollution buildup and activated charcoal absorbs excess oil from your hair and scalp.
