A tiny copper‑linked peptide called AHK‑Cu was shown in lab tests to help human hair follicles grow longer and to make the special skin cells that control hair (dermal papilla cells) multiply more, while also slightly lowering cell death signals. The work was done in test‑tube and hair‑follicle cultures, not in real people.
