Cyanidin-3-O-glucoside and its derivative vitisin A alleviate androgenetic alopecia by exerting anti-androgen effect and inhibiting dermal papilla cell apoptosis.

Androgenetic alopecia (AGA), one of the most common forms of hair loss, lacks satisfactory treatment methods in modern society. This study employed an experimental design combining in vitro and in vivo approaches to explore the effects of Cyanidin-3-O-glucoside (C3G) and Carboxypyranocyanidin-3-O-glucoside (Vitisin A) on AGA. In human dermal papilla cells (HDPCs), both anthocyanins demonstrated inhibitory effects on androgen receptors, significantly reduced dihydrotestosterone (DHT) induced apoptosis of HDPCs, and regulated the secretion of Fibroblast growth factor 7 and Transforming growth factor beta 1. In vitro transdermal experiment revealed that both C3G and Vitisin A could penetrate mice skin, aided by the application of cream. Furthermore, in vivo experiments with mice indicated that application of C3G or Vitisin A cream effectively improved hair follicles miniaturization, regression, and apoptosis caused by DHT. The repression of Wnt10b and β-catenin expression induced by DHT was prevented by C3G and Vitisin A in both cell and mouse model. Consequently, these findings suggest that C3G and Vitisin A could be considered as alternative methods for alleviating AGA.
