Cool Violet Color+ Shampoo gently cleanses the hair while adding rich, cool violet tones to each strand. Use this violet-hued formula on highlighted, gray or white hair to neutralize yellow and brassy tones and restore vibrancy and shine between color services. It is also ideal for non-color treated hair to add a hint of color. Keep color-treated hair healthy and vibrant between salon visits with our Color+ Shampoos. They provide maximum versatility and control the depth of color for healthier, shinier hair.
