How Does Macadamia Oil Help Hair And Scalp?
Anecdotal evidence suggests that using macadamia oil is extremely beneficial for the hair and scalp. It is said to improve hair texture, structure, and elasticity. It may also increase hair shine, provides frizz control, and repair damaged hair. But, does science agree with these benefits?

It may even help in sebum production. It also has antioxidant properties, which offer UV protection (1).

Macadamia oil is a triglyceride oil and contains up to 80-84% of monounsaturated fatty acids (8). This means it can be used as a hair moisturizer.

Squalene – which is present in sebum – and campesterol and stigmasterol – which may strengthen hair – are also found in this oil. Other nutrients found in macadamia oil include calcium, magnesium, sodium, potassium, niacin, phosphorus, and folate (3). Research shows that a deficit in these nutrients may cause hair loss (9).
