Spa Master 900 Lightening Powder is a professional hair bleaching powder designed to lift color up to 8 levels. It uses a trio of persulfates—potassium, ammonium, and sodium—to remove pigments from natural hair and even lightens existing dyes. The formula is ammonia-free and includes conditioning agents to help prevent dryness. It can be mixed with developer to create a thick cream and, when used with oils, helps reduce acidity and promote more even, brighter results. It removes natural base color and grey hair and can lift dark synthetic dyes, with application on dry hair following the package instructions.
