Bananas are a tasty source of potassium, vitamin C and other vitamins and minerals but the tropical fruit can also be used to make a mask that leaves hair shiny, moisturized and sweet smelling. Peel a banana and mash it in a bowl with a fork. Add 2 tsp. honey and mix well with the spoon. You may also add yogurt or avocado. Smooth the mixture all over your hair, cover and leave for 10 mins.
