Hair restoration protocols using peptides that target follicle regeneration, Wnt signalling, and scalp vascularity. We are no longer blocking baldness — we are rebooting the follicle from the inside out. GHK-Cu is the anchor compound here: a naturally occurring tripeptide that modulates 4,192 human genes, acts as a safe copper chaperone, and signals extracellular matrix remodelling at the dermal papilla. This hub covers the Wnt-signalling pathway, DHT-mediated damage, and the supplement cofactors that support topical and injectable approaches.
