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. Web3.1 Introduction to photobleaching. In the ideal case, an incident photon of appropriate wavelength is absorbed by a fluorophore, promoting the fluorophore to an excited state; subsequently, the fluorophore relaxes down to its ground state by emitting a photon. In reality, it is possible that the incident photon can break the fluorophore with the result that … small stuff home improvement https://cannabimedi.com
