A hair dryer is an electrical appliance used to dry and style hair by blowing warm or hot air over wet hair. It works by drawing in air and passing it over a heating element, then directing the heated air through a nozzle toward the hair. This process speeds up the evaporation of water, helping hair dry much faster than air drying.
Modern hair dryers come with different heat and speed settings, allowing users to control airflow based on hair type and styling needs. Many also include cool air options, which help set hairstyles and reduce heat damage. Attachments like concentrator nozzles help focus airflow for straightening, while diffusers spread air evenly for curly or wavy hair.
Hair dryers are commonly used at home, in salons, and during travel. When used properly, they help save time, improve styling results, and add volume and shine to hair. However, excessive heat can damage hair, so it is important to use the correct settings and maintain a safe distance while drying.
