creativity with no limits – every hair dream realized

a breakthrough in biosciences
K18Peptide™ was patented after a decade of scanning and testing the 1,242 decapeptides that cover the entire keratin proteome. Our miracle molecule carries amino acids into the cortex of hair to reconnect keratin chains and reconform disulfide bonds to bring damaged strands back to their original, youthful state.
