Avocados are the real magical fruit; they can be used for both hair and skin. High in biotin, which stimulates cell growth in the body, avocadoes are known for their anti-aging properties. Used as a hair mask, the avocado will lock in moisture along with vitamins and omega-3 fatty acids. Pureed alone or with honey, lemon or eggs, it can make a great facemask or moisturizer for the skin. Additionally, because of the vitamin A+E found in avocados, like aloe vera it can be used as a sunscreen or to treat sunburns.
