questions?
We have answers.
All hair has damage deep on the molecular level. Salon services add to this already existing damage. When hair is weak, it appears brittle, dry, and dull, and can’t hold on to color or styles as well. This makes it harder to get the salon results you want, without compromising your hair health.
We created this 2-step salon-exclusive service to repair existing + service damage—protecting your hair health while achieving the service you want. With truly healthy hair, any damage level can get their dream look without compromise. Ask your stylist for K18REPAIR™ to get healthier hair through every transformation.
