Avocado oil contains a high percentage of Vitamin E, as well as potassium, lecithin, and many other nutrients which can nourish and moisturize your skin. The oleic acid also promotes collagen production, which helps grow new skin. This accelerates the healing process, helping with issues like sunburn.
From the outside, avocado oil can benefit your hair, as well. Treating your hair with avocado can moisturize, repair, and strengthen your hair. A 2015 International Journal of Trichology study found that minerals like those in avocado oil can help seal cuticle cells, which can prevent hair from breaking.
