The study investigates the effects of Dendrobium officinale polysaccharide (DOP) on hair regrowth in androgenetic alopecia (AGA) mice. Results indicate that DOP improves hair regrowth in a dose-dependent manner, with the high-dose group showing significant improvements in hair coverage, follicle density, dermal thickness, hair bulb diameter, and anagen phase proportion. The treatment was linked to decreased SRD5A1 expression, increased CYP19A1 expression, reduced local dihydrotestosterone and testosterone levels, and elevated p-ESR1 and KRT28/KRT71 expression. These changes suggest that DOP influences local steroid metabolism, ESR1 activation, and keratin-related follicular responses, enhancing follicular morphology and cycling. The findings propose a framework for further exploration of DOP in treating AGA.

This study explores the potential of quercetin and kaempferol, two plant-derived flavonoids, as dual inhibitors of JAK3 kinase and 5-alpha reductase type 2 (5-AR2) for treating androgenetic alopecia (AGA). Using molecular docking simulations, quercetin showed the strongest binding affinity to JAK3 kinase, surpassing the reference drug tofacitinib, while both flavonoids demonstrated moderate binding to 5-AR2, within the inhibitory range for polyphenolic flavonoids. Quercetin's favorable ADMET profile, including suitable skin permeability and safety, highlights its promise for topical application. These findings support further research into these compounds as safer, natural alternatives for AGA management.
