Well as you know vaseline can be used for many different things, make-up, skin... and hair! Do you find after drying or straightening your hair you get split ends that ruin your look and make your hair look frizzy?
Well take a small amount of vaseline and rub it evenly in your hands... then apply it to your hair! And all those horrid frizzy bits dissapear!
Be careful not to apply too much though...otherwise your hair may get greasy and you dont want that!
