Macadamia oil is the non-volatile oil expressed from the nut meat of the Macadamia tree, native to Australia. Macadamia oil is reconstructive and hydrating. Squalene is a naturally occurring antioxidant in Macadamia oil that helps to reduce the oxidative stress on our skin and scalp by preventing loss of moisture. The fatty acid content is the real winner for skin and hair. Those fatty acids help to add shine, strengthen, and nourish the hair follicles, which in turn fight off hair loss and brittle strands.
