Keep your hair under control and neutralized with this toning hair mask. A dark envy green, color-depositing toning mask that is made with the highest concentration of dyes to neutralize unwanted red undertones. Red undertones in dark bases can be caused by sun, water/chlorine, bleaching/highlighting and chemical processes or excessive use of hot tools. This mask works best for levels 1 - 4 and for those with virgin or all-over black to dark brown hair. Leaves hair with a cool, glossy finish and a signature fragrance of citrus, jasmine and cedarwood.
