Bleach bathing hair, also known as bleach washing, is a hair bleaching technique involving a mixture of bleach and shampoo applied to wet hair. It is a gentler alternative to traditional bleach treatments, utilizing lower bleach concentrations and longer processing times.
Bleach bathing offers several advantages: it preserves hair health, reduces brassiness, lightens multiple shades, and provides a gradual, buildable lift. Its origins can be traced back to the late 1990s when hairstylists sought milder bleach methods for over-processed or damaged hair.
