June 2012 in “International Journal of Molecular Medicine” This study observed that while X-ray radiation did not alter major hair keratin composition in mice, it decreased hair follicle stem cell markers and increased Krt5, suggesting potential as a radiation biomarker.
May 2026 in “International Journal of Cosmetic Science” This study found that UV radiation exposure during a simulated Brazilian summer caused more significant mechanical damage to natural hair than bleaching, although both caused comparable structural alterations, with double bleaching leading to the most severe protein degradation.
This study found that UV radiation-induced fibroblast depletion in the skin is primarily due to a deregulated inflammatory response, with T cells aiding fibroblast survival under stress.
April 2019 in “Journal of Investigative Dermatology” This study found that ultraviolet radiation causes significant damage to human hair follicles, including increased cell apoptosis and oxidative DNA damage, but this damage may be mitigated by topical caffeine.
