IPA COPYRIGHT: ASHP The changes in hair color that are attendant upon bleaching of hair with hydrogen peroxide or upon exposure to sunlight using reflectance measurements were examined using brown and red hair samples obtained from 2 female subjects. Results obtained suggest that phaeomelanin, the colorant of red hair, is more resistant to chemical or photo-degradation than eumelanin, the pigment in brown and black hair.
