K18REPAIR™ Starter Set

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.

step 1: repair hair to the core pre-service

PRO mist – Fortify hair to restore up to 99% elasticity – Improve hair’s resilience to prevent damage during + after services – Deliver stronger hair over time – Make color last longer + fade slower when paired with K18 mask usage at home – pH 7.5-8.0 swells the hair cuticle open for effective repair pre-service

step 2: reverse damage post-service

PRO mask – Reverse damage from lightener + color, chemical services, and heat* – pH 5.0-6.0 helps close the cuticle + seal K18PEPTIDE™ into the hair for lasting results – Soften + detangle all hair types with lightweight emollients
