Joico K-Pak Shampoo + Conditioner Duo work together to repair, hydrate and strengthen damaged or chemically treated hair. While the shampoo gently cleanses for a colour-safe cleanse, the conditioner deeply nourishes from the inside out to heal damaged strands. Both are formulated with our exclusive SmartRelease Technology to naturally defend against damage while restoring hydration and shine. More effective together, this daily reconstructive shampoo and conditioner duo will restore elasticity, eliminate tangles, and help you to maintain radiant, healthy-looking hair
