Macadamia oil is used in cosmetics and skin care because it is nutritive, 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.
