NMN promotes hair growth by regulating the paracrine system of cells. NMN inhibits IL-6 secretion while promoting the upregulation of VEGF and β-catenin gene expression, and simultaneously downregulating the expression of DKK-1 and AR genes. NMN reduces oxidative stress levels by activating antioxidant enzymes, thereby inhibiting the NF-κB p65 inflammatory pathway. The figure was drawn by Figdraw (ID: WYRPAb5f17).
