Setup, Compatibility & Care
Before beginning, perform a patch test 48 hours in advance to ensure no allergic reaction occurs. Protect your clothing and surrounding surfaces, as permanent dye can stain fabrics. Apply the mixture evenly, starting from the roots where grey hair is typically most prominent, then combing through to the ends. After the processing time, rinse thoroughly with lukewarm water until the water runs clear, and follow up with a conditioning treatment to lock in moisture. For maintenance, use color-safe shampoos to preserve the vibrancy of the black pigment.
