It removes natural base color and grey hair, lifts dark artificial dyes, and does not contain ammonia. The powder is formulated with moisturizing ingredients to help prevent dryness. How to use: mix with a developer to form a thick cream, apply to dry hair, and follow the directions on the package for timing based on the developer strength.
