Decapeptide-18, also known as CG-WINT, is a synthetic peptide that plays a significant role in promoting hair growth. It is composed of arginine, cysteine, glutamine, glutamic acid, histidine, threonine and valine. It is derived from the Wnt10 signaling pathway and is designed to stimulate the formation of hair placodes, which are essential for hair follicle development. This peptide exhibits higher stability and skin penetration compared to the natural Wnt10 peptide, making it effective in activating hair follicles and promoting the differentiation of hair follicle epithelial stem cells into hair keratinocytes. Additionally, Decapeptide-18 is recognized for its potential in enhancing hair density and strength, making it a valuable ingredient in hair care formulations aimed at combating hair loss and promoting hair growth.
