K18 Leave-in molecular repair hair mask 5ml is the next level of breakthrough in hair repair technology!

Your hair can suffer from damage from bleach, hair colour, chemical services, heat styling and sun damage. This damage can go below the top layer of your hair and into the lower levels, the deepest of these are made up of polypeptide chains.

K18 Scientists spent a decade researching the keratin chains in the inner hair shaft and found one unique sequence that was just the right size and molecular structure to reconnect broken polypeptide chains. This patented K18peptide brings hair back a like-new, youthful state.

K18 reconnects broken polypeptide chains, it restores the hairs core structure, renewing hairs strength and elasticity. This treatment goes deep into the hairs structure repairing your hair at a molecular level so it is long lasting, as it remains in the hair even after being exposed to water and shampoo.
