ACETYL TETRAPEPTIDE-3

Acetyl Tetrapeptide-3 is a synthetic biomimetic peptide composed of four amino acids with an acetyl group at the N-terminus, specifically designed to target hair follicle anchoring and scalp health. It works by stimulating extracellular matrix proteins such as laminin-5 and collagen IV in the dermal papilla, helping to strengthen the attachment of hair follicles to the scalp and reduce hair loss. Formulators choose it primarily for anti-hair loss and scalp treatment products, often combining it with other actives like biotinoyl tripeptide-1, as it addresses follicle anchoring through a distinct and complementary mechanism of action.
