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.

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.

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.
