K18 Leave-In Molecular Repair Mask

K18 Leave In Molecular Repair Mask is a leave in treatment that works on the molecular level to reverse hair damage in about four minutes. It repairs damage from bleach, color, chemical services, and heat, restoring strength, softness, smoothness, and bounce.

How to use: After shampooing, skip conditioner and towel dry your hair. Apply from the mid lengths to the ends, or all over for very damaged hair. Wait at least four minutes, then style. Do not rinse.
