Why would a balloon attract your hair without touching it?

Because electrons are negatively charged, the balloon acquires a negative charge, while the hair, with its loss of negative charges, now has a net positive charge. So the balloon and hair have opposite charges, and opposite charges attract each other. That’s why the hair gets pulled toward the balloon (Figure 2).
