Color Mask is a unique intensive treatment that maintains and deepens the present shade of colored hair. It’s perfect for refreshing the shade of color treated hair between salon visits, darkening or lightly toning to give you the look of freshly treated hair.

These work to repair and reconstruct chemically treated and damaged hair, keeping your locks strong and beautiful. The Color Mask Reconstructive Treatment is available in 16 unique shades. Use them alone or mix them together to create your own custom color. Everyone’s hair is different and their treatment should be as well.
