There are thin (usually coils) of wire just thick enough so that when the right current is passed through they glow red/orange and give off lots of heat. Then there is a motor behind it with fan blades attached to it. This sucks air in the back of the hairdryer and blows it past the coils and the heat transfers to the air (heat always goes to cold, so the heat from the hot wires travel into the air). This air is blown onto your head. As I just said hot goes to cold so the heat from the air transfers to your hair and evaporates the water off. Hot goes to cold because if you left everything it would be the same temperature (room temperature). Everything in a room is the same temperature. You bring something hot in like a cup of tea and the heat will spread out evenly around the room so the tea will get alot colder and the room a little warmer as a result.

?????
A resistor and a blower
The air just blows across a heated resistor. The resistor gets hot from the friction of electricity flowing through it.
BTW Sounds like your mom needs to avoid appliances and you guys can just drip dry if you've tried ti 94 times.

electricity heats up the coils inside of the dryer to produce heat.. the blowers then blow the heat out. its kind of like a light bulb. theirs filaments inside to complete an ac circuit. as the electricty flows there is resistance. resistance causes heat

just like a toaster with a fan in it.
