What it is: A luxurious treatment with unique melt-down technology that pampers hair with a subtle warming sensation as it replenishes moisture. What it does: This mask is formulated with the brand's proprietary CR-4 Repair Complex, which includes nutrient-rich mafura butter and kalahari melon seed oil and envelops the hair shaft with a cushion-like coating of concentrated fatty acids vital to rebuilding, nourishing and protecting hair. A blend of three clinically-proven actives instantly recreate hair's depleted lipid barrier, restoring the protective layer to promote health and prevent future damage. How to use: Apply on clean, damp hair, starting at the damaged ends of your hair and working your way up toward regrowth, being careful not to concentrate too much on the scalp. Leave on for 10 minutes then rinse. On dry hair, apply as you would a hydrating, reparative warming mask. 6 oz.
