K18REPAIR™ is a 2-step salon-exclusive damage repair service powered by K18PEPTIDE™ to protect, strengthen + preserve all hair types through lightener, color, chemical services, and heat*. Feel confident in every service + deliver hair like new*—no matter what you put it through.
K18REPAIR™ is powered by the reparative K18PEPTIDE™ to reconnect broken disulfide bonds + polypeptide chains for immediate + lasting repair at the deepest, molecular level of hair. It’s more than a bond builder—K18PEPTIDE™ is biomimetic to hair and works past the outer cortex (where bond builders work)—so water can’t wash away your results.
2 steps, 4 minutes each. No extra rinse required.
