Is it a hair dryer? If you just blow dry your hair, the power is generally below 800w W, so it should be no problem to use it in the dormitory. If it is a professional blower fan, the power is generally around 2000w W. It should be no problem to use the wall socket, but whether it can be used depends on whether the management of the house allows it, such as whether there are regulations restricting the use of large electrical appliances in the dormitory of the school and so on. If you are in the school dormitory and use less electricity, pay attention to the safety of electricity use, you should be able to use it.

An electric heating appliance for hair drying or styling uses a motor as the prime mover and is directly equipped with blades to work. The motor drives the fan blades to rotate, sucks air from the air inlet, is heated by the electric heating element, and blows out hot air from the air outlet. Electric heating elements are generally household nickel-chromium wires. By changing the terminal voltage of the motor, the air volume at the air outlet can be controlled, and the temperature can be adjusted by tapping the heating wire, which is more suitable for hairdressing and hair care.
