b-ex Slow Color Shampoo Ash 80ml This color-care item adds shine and moisture while helping prevent dye from washing out, replenishing cool-toned pigments that tend to fade during the color-loss process. It suppresses unwanted redness and enhances the longevity of the ash tones that are the essence of THROW color. Features a fresh botanical herb fragrance. How to Use: After thoroughly wetting your hair with warm water, take an appropriate amount in your hands, lather, and wash. Rinse well until the water runs clear and no more color comes out.
