From preventing frizz to defending against damage, the benefits of natural oils are undeniable for curly hair. But not all oils are created equal. Some are better left in the kitchen, while others deserve a place in your beauty routine. Here are a few of our favorite oils for soft, healthy, moisturized curls.Mongongo Oil Mongongo oil comes from the nut of the mongongo or manketti tree, which is native to southern Africa. Rich in vitamin E and essential fatty acids, this oil acts as a protective barrier to help seal moisture into each hair strand. It also leaves curls looking incredibly shiny.

The oil found in its seeds is rich in omega-6 fatty acids, which makes it a uniquely nourishing moisturizer for parched curls.

Unlike other oils that work at a surface level, coconut and avocado oils are able to absorb into the hair shaft thanks to their small molecular size. This makes them ideal for low porosity curls, as well any texture that needs deep moisture to prevent dryness and breakage. Find them in: Curl Immersion Triple Treat Deep Conditioner
