Christophe Robin’s Color Shield Cleansing Mask is an ultra-conditioning shampoo for a deep hair treatment. This once-a-week mask is a gentle, low-foaming creamy shampoo to prolong the vibrancy of color-treated hair. Developed with camu-camu berries and comes with a delicate pearlescent texture for nourished hair and a long, lasting radiance. Key ingredients: Camu-camu berries are rich in vitamin C that protects the hair from fiber oxidation and boosts hydration and shine. Sunflower seed extract is rich in antioxidants that care and protect and reduce color fading. Macadamia oil restructures the hair fiber and offers a protective film to seal nutrition. How to use: Apply the mask from root to tip onto wet hair. Leave on for 5 to 20 minutes. Gradually add water, massage the scalp and create a low-foaming lather. Rinse thoroughly. For an even more intense result, apply the mask evenly on wet hair and gently massage from the roots to the ends. Leave on for 15 to 60 minutes, gradually add water, massage the scalp and rinse thoroughly.
