January 2009 in “International Journal of Trichology” This review discusses the mechanisms by which sunlight exposure aggravates hair aging and highlights the role of hair pigments in providing photochemical protection, reporting no new results.
May 2026 in “Journal of Photochemistry and Photobiology” This review found that solar radiation, pollution, and trace metals cause significant damage to human hair, with factors like UVB radiation primarily affecting light-colored and bleached hair; most data were derived from in vitro and ex vivo simulations.
September 2025 in “International Journal of Cosmetic Science” This study observed that exposing human hair keratins to heat or UV treatments led to modifications in cysteine residues, disrupting crucial disulphide bonds and potentially reducing the structural integrity of hair similar to prolonged styling or sunlight exposure.
