      As self-described hair care ‘liberators’, K18’s ethos is all about supplying you with the tools you need to express your identity, try new trends and have fun with your mane — without sacrificing the softness, strength and vitality of your hair.

      By understanding the biology of your hair the K18 team has been able to get to the (*ahem*) root of the problem of hair damage, and — crucially — discover one hero bioactive peptide that will return strands back to their most healthy state.

      Enter: the K18Peptide, a patented molecule that travels to the polypeptide chains (that’s the very innermost layer of your hair) where it repairs broken bonds and restores hair’s strength and elasticity. This is where biotech meets hair care!
