Why K18 Is Different — The Science of Biomimetic Hairscience™

Traditional hair masks condition from the outside. K18 works from the inside. The patented K18Peptide™ is a bioactive peptide scientifically designed to mimic the structure of the hair’s natural keratin chains. When applied to damaged hair, it reconnects broken polypeptide bonds — the same bonds severed by bleach, heat, and chemical processing — reversing damage at the molecular level and restoring hair to its original, healthy state.*
