May 2026 in “Journal of Photochemistry and Photobiology” This critical review examines the oxidative damage to human hair caused by solar radiation and pollution, highlighting that protein and lipid oxidation lead to structural breakdown. The study finds that UVB radiation primarily affects the hair cuticle, while UVA and visible light impact the cortex, with light-colored and bleached hair suffering the most damage. The review emphasizes that solar radiation is the primary damaging factor, but trace metals, air-borne pollution, and hair care practices also contribute to hair degradation. Strategies for hair protection should consider the specific combination of hair characteristics and environmental exposures, referred to as the "hair exposome."
