Nourish and enhance natural or color-treated brown hair with Shade Variation Mask in Ash Brown from Christophe Robin. This mask is specially formulated to enhance ash tones in natural, color-treated or highlighted brown hair. Brown hair can take on undesirable red and mahogany tints and become dull with time. The nourishing ingredients of this product-almond butter and buriti oil-combined with an acidic pH of 4. 5 minimize porosity, nourish your hair, fix natural oxidation and evenly distribute color. Licorice extracts and the selection of pigments restore a natural, cool brown color with no brassy highlights.
