Through dyeing or bleaching processes, hair is weakened in its natural structure, making it less protected against stress from artificial heat, pollution, UV rays, chlorine, or sea salt. Over time, hair color fades and oxidizes, leading to unwanted tones. The Color Shield Mask specifically addresses this issue - it provides a powerful combination of antioxidant vitamins that preserve hair color from oxidative stress and sustainably strengthen the hair fiber. The high concentration of macadamia oil, rich in Omega-9, helps deeply nourish and restore hair fibers damaged by successive dyeing processes. The acidic pH value tightens the hair's cuticle layer, further binding the color pigments in the hair core and enhancing color intensity. The hair color appears particularly shimmering, radiant, and has a unique glossy finish; as vibrant as on the first day of dyeing.
