Platelet-rich plasma (PRP) has been reported recently as a potential therapeutic approach for alopecia, such as androgenetic alopecia, but the exact mechanisms and effects of specific components of this recipe remain largely unknown.In this study, we identified that platelet factor 4 (PF4), a component of PRP, wilds of eldraine prerelease guide significantly suppressed human hair follicle growth and restrained the proliferation of human dermal papilla cells (hDPCs).Furthermore, our results showed that PF4 upregulated androgen receptor (AR) in human dermal papilla cells in vitro and via hair follicle organ culture.Among the hair growth-promoting and DP-signature genes investigated, PF4 decreased the expression of Wnt5a, Wnt10b, LEF1, HEY1 and IGF-1, and increased DKK1 expression, but did not affect BMP2 and BMP4 expression.

Collectively, Our data demonstrate that PF4 suppresses human hair follicle growth possibly via upregulating androgen receptor signaling and modulating hair growth-associated 12n/1200 wella genes, which provides thought-provoking insights into the application and optimization of PRP in treating hair loss.
