A hair dye and dyeing method that vividly colors hair without damaging it, regardless of the type of dye used. The hair dye contains specific surfactants and adjusts pH to match the hair's isoelectric point. This allows the dye to adhere to hair without charge, penetrate inside, and dye vividly without harming the cuticle. The surfactants are an anionic acylamino acid with a cocoyl group and a nonionic alkyl glucoside. The pH adjuster keeps the dye solution around the hair's isoelectric point.

Reducing hair damage when re-lightening previously dyed hair by using a dedicated oxidative dye composition and de-dyeing composition. The oxidative dye composition has a low coupler-to-dye intermediate ratio compared to standard oxidative hair dyes. This allows better destaining with glyoxylic acid or derivatives when the hair is re-lightened. The low coupler ratio reduces hair damage compared to regular oxidative dyes. Using this specialized oxidative dye and de-dyeing kit can significantly reduce hair damage when re-lightening previously dyed hair.
