for Macadamia Haircare. Macadamia oil contains the highest amount of Omega 7 than any other nut oil. Omega 7 most closely resembles human hair sebum and thus mimics the scalp’s natural oil production. It is lightweight and non-greasy with no build-up. The line is free of harsh sulfates, and are color-safe, paraben-free, gluten-free and cruelty-free. The products contain a Pro Oil Complex, a unique blend of Macadamia and Argan Oils to nourish and repair hair from the inside out. I’ve loved every product I tried. My favorite is the Nourishing Moisture Oil Spray. It can be used on both dry and wet hair. It is an ultra fine mist that instantly absorbs in the hair. It adds major shine and softness, without the greasyness and weight of most shine sprays. It also offers uv protection. So go nutty with Macadamia hair, and have the refined results you desire ….
