Macadamia oil is cold pressed from the nuts of the macadamia nut tree, which is predominately found in Hawaii where the nut is actually allowed to fall from the tree and then husked. The oil is a pale yellow, almost colorless, refined vegetable oil that is light, non-greasy and easily absorbed into the skin and hair shaft. It has a slight nutty flavor and is one of the highest sources of essential fatty acids.

Originating from trees in Australia, macadamia nuts are popular for their subtle, nutty flavour and rich texture. Macadamia nuts are nutritionally dense and are one of the highest natural sources for healthy fatty acids. The oil produced from the nuts of the macadamia tree packs a concentrated dose of these fatty acids, magnesium, and vitamin E. One of the most commonly used natural oils in hair products, macadamia oil is reportedly able to transform dry, damaged hair.
