Amika Fadeblock is here to lock in hair color vibrancy. This pre-shampoo treatment acts as a sealant, creating a barrier that minimizes color fading during washing. Applied before shampooing, it helps to preserve the intensity and longevity of color-treated hair. The formula works to shield strands from water and cleanser-induced color loss, maintaining that salon-fresh look. This color seal also nourishes for healthier, more vibrant hair.
