Joico K Pak Shampoo. A gentle, rich cleansing shampoo that restores weak and depleted hair to its optimal strength and condition. This reconstructing shampoo replenishes amino acids and fills in damaged areas of the cuticle while hydrating and protecting with aloe and antioxidant Vitamin E. Your hair will become stronger and more resilient to external damage. Plus, because what’s been missing is being replenished, your hair will be more responsive to styling.
