Intensive conditioning for ultra-dry hair. This dual-usage hair mask with shea butter is perfect as a once-a-week deep conditioning treatment. Apply after shampooing and rinse out. For coarser, hard-to-manage hair, use as a leave-in treatment after shampooing. This mask helps restore moisture and manageability to ultra-dry, thick or unruly hair. Shea butter comes from the Karite tree. The fatty acids extracted from the nut of this tree provide moisture far superior to other vegetable based butters. This is why we use Shea butter as the main ingredient in our ultra moisturizing family of products.Â Each moisturizing formula in the collection, with shea butter, hydrates and smoothes hair, leaving it manageable and touchably soft.
