That's right, not only is avocado a delicious lunchtime treat, it's also a magical healing product that can rid your hair of split ends. Minerals found in avocados can help to seal the cuticle as well as adding vitamins and nutrients to soften and heal the hair. Combining this with olive oil leaves your hair sleek and shiny, and the end product is a wonder. Leave this mask on for about 30 minutes to see the full effect.
