Schwarzkopf Igora Royal permanent hair color offers total coverage and unparalleled intensity while maintaining scalp comfort. Its formula helps even out color even on porous hair. The pigment penetrates the hair effectively and is locked in for long-lasting, vibrant color.
Mix 1 ounce of color to 1 ounce of peroxide (1:1 ratio) and leave on for 35 to 45 minutes, depending on the percentage of white hair. Rinse thoroughly and shampoo followed by conditioner.
