Don’t let water wash away your art. This shampoo is specifically formulated for the needs of colored and highlighted hair. Thanks to Fruit Acids, it performs a natural acidifying action that seals the hair scales, locking color pigments inside the fiber. The result is color that resists washing, remaining vibrant, fresh, and deep as if just applied. How to use: Apply to damp hair, massage gently to awaken highlights, and rinse. Repeat the wash if necessary.
