Redken's Acidic Color Gloss Sulfate-Free Shampoo is designed to extend color vibrancy for up to 32 washes. Its acidic pH formulas help seal the cuticle, enhancing shine and locking it in. The sulfate-free cleansing ensures gentle treatment, making hair look and feel revitalized instantly. When compared to non-conditioning shampoos, the Acidic Gloss leave-in provides superior results for colored and gloss-treated hair.
