摘要:
The process for bleaching hair using light includes first, applying a sufficient quantity of a composition containing at least one optical photosensitizer and a compound capable of providing a hydrogen radical to strands of the hair to be bleached and allowing the composition to act for up to 60 minutes on those strands; then, irradiating them with light of a wavelength or wavelengths selected from visible and ultraviolet wavelength ranges capable of activating the at least one optical photosensitizer and having an intensity sufficient for bleaching them, and subsequently rinsing and drying the bleached hair. This process does not require excess hydrogen peroxide and is thus particularly gentle to the hair.
