"Oils are my best friend — especially olive and macadamia oils. As a deep treatment, I add a few drops of macadamia oil to Africa's Best Organics Hair Mayonnaise. Then, I cover my hair in a shower cap and use my bonnet hair dryer for about 10 to 15 minutes on a low heat setting for a deep treatment. I find that the added macadamia oil works best on my hair type for curl definition." — Kara Kia, assistant editor at POPSUGAR
