Acetyl tetraptide-3 is 4 amino acids biomimetic peptide derived from a growth factor, it has a sequence Ac-Lys-Gly-His-Lys-NH2 (KGHK) specially designed to fight the symptoms of hair loss and stimulate hair growth. With its ability to stimulate the synthesis of follicle extracellular matrix proteins (Collagen I and III, laminin), Acetyl tetrapeptide-3 helps the renewal of dermal papilla cells and opposes the stiffening of the sheath of the hair follicle that causes hair loss.
