Explanation:

When a plastic comb is run through hair, static charge transfer occurs: the comb gains electrons (becomes negative) while the hair loses electrons (becomes positive), resulting in opposite charges. Opposite electric charges attract each other, which causes the hair to stick out toward the comb.

The comb and hair have opposite charges.
