This Wella Professionals Color Touch product is an ammonia-free formulation designed for refreshing existing hair color and providing gentle coverage for gray hair. It utilizes a semi-permanent dye system, meaning it deposits tone without drastically altering the natural base color, fading gradually over time. Included in this offering is an essential Root Kit to perfect color blending and a nourishing Hair Mask to ensure the treated hair remains conditioned and vibrant. The specific shade mentioned is 'Chocolate,' ideal for rich, warm brown tones.
