A handheld electric hair dryer is a personal care appliance used to dry and style hair by blowing warm or hot air. It is commonly used in homes, salons, and barber shops. The device consists of an electric motor, a fan, a heating element, air vents, a nozzle, and control switches for temperature and speed. Some models also include cool air settings and different attachments for styling.
In operation, the hair dryer is plugged into a power source and switched on. The motor drives a fan that draws in air and pushes it over the heating element, warming the air before it is blown out through the nozzle. The user directs the airflow onto wet or damp hair while adjusting heat and speed settings as needed. The warm air helps evaporate moisture from the hair, drying it quickly, while airflow direction helps in styling. After use, the dryer is switched off and allowed to cool before storage.
