As shown in the figure, in dry weather, Xiaohong combs her hair with a plastic comb and finds that the more she combs her hair, the more fluffy it becomes. This is because _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _. When combing the hair with a plastic comb, the hair is charged due to friction; Among them, the charge of hair and comb is different, and the charge of hair is the same, which repels each other, so the more combed the hair, the more fluffy it becomes.

Because the hair is light and small with different charges, and the comb is charged and has the property of attracting light and small objects, so the hair will float with the comb.

Therefore, the answer is: friction electrification, the same kind of charges repel each other; Charged objects can attract light and small objects.
