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.
In this study, a polyphenol and biotin supplement improved skin roughness and significantly reduced hair shedding, but did not demonstrate clear superiority over placebo in overall skin outcomes.

July 2020 in “International Journal of Cosmetic Science” This study found that while all hair removal techniques increased axillary erythema and skin dryness, shaving caused less erythema but more dryness than plucking or waxing, without affecting post-inflammatory hyperpigmentation or other skin properties.
January 2024 in “Journal of cosmetic dermatology” This study found that Silibinin-loaded polymeric micelles significantly protected human hair from UV-B induced structural and chemical damage by preventing increases in roughness and reducing protein loss.
June 2026 in “ACS Applied Polymer Materials” This study reports a method for fabricating biofunctional polymer fibers by using DNA-programmable cell-free protein synthesis integrated through solution blow spinning, enabling in situ protein production and potential applications in respirators, sampling swabs, and other advanced materials.
