A hairdryer is an electrical device used to dry and style hair by blowing warm or hot air. It typically consists of a motor, a fan, and a heating element. When turned on, the fan draws in air, which is then heated and directed through a nozzle. Hairdryers often come with various settings for heat and speed, allowing users to customize their drying experience. Many hairdryers also include attachments, such as diffusers and concentrators, to help achieve different styles. Diffusers are useful for curly hair, as they help maintain the natural curl pattern, while concentrators focus the airflow for precise styling.
