The first step in getting gum out of your hair is to freeze the gum with ice cubes. It will eventually harder as a result of being frozen and you can then break it away from your hair. This should get rid of the bulk of the gum stuck in your hair. If there is still some gum in your hair after this procedure, use baby oil to coat the gum. Then use a comb to work the oil into the gum and the gum out of your hair. Of course, once the gum is gone your hair will be an oily mess. To get the baby oil out of your hair put baby powder in your hair to soak up the oil then shampoo normally. Although it takes a while, this is a reliable way to get gum out of hair.
