Sunscreens and Hair Photoprotection
Dermatologic Clinics, 2006Photoprotection as it pertains to hair is not a common topic addressed by the dermatologist. Hair is nonliving and requires no protection from ultraviolet (UV) radiation because carcinogenesis of the hair shaft itself is not possible. If hair proteins are altered by sun exposure, damaged hair can be removed and replaced by new growth.
