Dry hair stand when combed with a plastic comb because they get charged. When rubbed with fur ebonite gets a negative charge. When fur is rubbe^ with ebonite, fur acquires positive charge. Normally, the layers of cloud facing the earth get negatively charged. Dry air is a bad conductor (or insulator) of electricity.
