Why you’ll love it: This sulfate-free shampoo is a favorite for color-treated hair—it gently cleanses without dulling or stripping your hue. Formulated with Color Wow’s unique no-residue technology, it leaves nothing behind that could weigh hair down or block follicles. The result: vibrant, glossy color and hair that feels fresh, light, and healthy after every wash. How you’ll use it: Apply to wet hair and massage into the scalp to create a rich lather. Rinse thoroughly, then repeat for a deeper cleanse if needed. Follow with your favorite conditioner for extra smoothness and shine.
