To remove gum from hair without cutting it, start with a jar of creamy peanut butter or a bottle of olive oil. Use fingers or an old toothbrush to apply the peanut butter or oil, and completely cover and saturate the gum.
Let the gum sit with the oil or peanut butter on it for a few minutes. The oil in the products causes the chewing gum base to become stiffer and less sticky. After it sits for a while, carefully remove the gum from the hair. Vegetable or olive oil works particularly well to remove gum from eyebrows or eyelashes. After the gum is out, wash the hair thoroughly.
Another way to remove gum from the hair is to freeze it and pick it out. Hold a piece of ice on all sides of the gum until it becomes cold and brittle, at which time it can be picked out.
Rubbing the strands of hair and gummy area with petroleum jelly also makes it slippery enough to comb right out. This may pull the hair and might be a little painful, so it may not be the most effective method for children. After removing the gum, make sure to wash the hair to remove any oil, food or gum that may be left.
