May 2026 in “Bioactive Materials” This study reported that in degenerative alopecia, Zn²⁺/Cu²⁺-dependent proteases are downregulated and destabilized, and a specially developed microneedle patch reactivated these enzymes, reduced senescence, and enhanced hair regeneration in an animal model.

July 2016 in “Cold Spring Harbor Perspectives in Medicine” The p53 protein has complex, sometimes contradictory functions, including tumor suppression and promoting cell survival.
May 2026 in “Research Square” This research reports that the polyG fragment within the Hoxc13 protein alters its gene regulatory functions, which could have influenced mammalian hair evolution by affecting pathways related to hair follicle development.
March 2026 in “Journal of the mechanical behavior of biomedical materials/Journal of mechanical behavior of biomedical materials” This study investigated the mechanical response of the human hair cuticle to strain and found that cuticular deformation directly corresponded with fiber elongation, revealing significant molecular-level changes in disulfide crosslinks but maintained structural stability, highlighting the role of the cuticle in stress resistance.
