When the weather is dry, I comb my hair with a plastic comb and find that the more I comb it, the more fluffy it becomes, and some hair will float with the comb. Why?

A: In dry weather, when you comb your hair with a plastic comb, friction and electrification will occur, which will make the comb and hair carry the same amount of heterogeneous charges; Because heterogeneous charges attract each other, some hair will float with the comb; Because hair has the same charge and the same charges repel each other, it will be more fluffy.
