K18 uses their own patented formula, K18Peptide™, as a scientific approach that uses biotech instead of traditional cosmetic chemistry in hair care. This formula carries amino acids inside the hair cortex to reconnect broken bonds and keratin chains, for hair like new in 4 minutes. Can be used immediately after chemical services to repair damage done during the service, and at home to keep hair in its healthiest, strongest state.
This peptide formula was discovered after a decade scanning and testing all amino acid sequences, covering the entire keratin proteome that makes up human hair DNA. This K18Peptide™ discovery is one unique sequence to bring damaged hair back to it's original, youthful state, with the key being to get inside the hair where real repair can be done.
