January 2008 in “Linchuang pifuke zazhi” This study found that betamethasone increased tyrosinase activity and melanin content in amelanotic melanocytes from human hair follicles, suggesting a potential mechanism for glucocorticoid treatment in vitiligo.
September 2022 in “Journal of Theoretical Biology” This study developed a mathematical model to explore hair follicle regeneration mechanisms, showing that low spontaneous apoptosis rates help regenerate hair follicles after ionizing radiation, while high rates lead to degeneration during the catagen phase.
