To use this hair color cream, begin by performing a patch test 48 hours before application to check for any allergic reactions. Once ready, mix the cream color according to the instructions provided, then apply it evenly to dry, unwashed hair. Start at the roots and work your way through to the ends, ensuring full coverage. Leave the product on for the recommended processing time, then rinse thoroughly with warm water until the water runs clear. Follow up with a conditioner to nourish your hair and lock in the color for a vibrant, long-lasting result.
