September 2001 in “Scanning” Hair treatments like bleaching increase friction by exposing tiny pores on the hair surface.
September 2024 in “Journal of Cosmetic Dermatology” This study found that quercetin-loaded solid lipid nanoparticles demonstrated positive protective effects on human hair against UV-B light, as they controlled microscopic surface roughness, reduced chemical changes, and minimized protein loss in vitro compared to other treatments.
