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.

a radically different approach

Until now, haircare products covered up damage with conditioning treatments that coat hair in oils, bringing superficial hydration and sheen, while repair treatments patch damage like internal glue – strong but brittle—and provide temporary results. K18 is the first product that actually heals your hair from the inside out.
