Photobleaching 뜻
WebNational Center for Biotechnology Information WebJun 2, 2024 · Photobleaching refers to the lightening of the hair through prolonged exposure to sunlight. The photobleaching process gradually turns dark brown hair into light brown hair. It can even lighten light brown hair into sun-kissed blonde hair. You may not have noticed it before, but your hair may be photobleached from spending time outdoors.
