Through dyeing or bleaching processes, hair is weakened in its natural structure and is therefore less protected against stress from artificial heat, pollution, UV rays, chlorine, or seawater. Over time, hair color fades and oxidizes, leading to unwanted tones. The Color Shield Shampoo provides an effective blend of antioxidant vitamins that preserve hair color from oxidative stress and sustainably strengthen the hair fiber. The acidic pH value tightens the hair's cuticle and binds the color pigments in the hair core, enhancing color intensity. The shampoo is sulfate-free and offers even damaged hair the gentlest cleansing, allowing for color-safe, frequent use. Hair color remains vibrant, fresh, and radiant; day after day.
