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 heating element, and a fan, which work together to evaporate moisture from wet hair. Hairdryers often come with various heat and speed settings, 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 enhancing natural curls, while concentrators direct airflow for precise styling. Hairdryers are popular tools in both home and professional salons.
