A hair dryer (also known as a blow dryer) is an electrical device used to dry and style hair by blowing hot or cool air. It works by accelerating the evaporation of water from the hair, making the drying process faster compared to air drying.
Key Features of a Hair Dryer:
1. Heating Element: Converts electrical energy into heat.
2. Fan: Blows air through the heating coils to produce warm airflow.
3. Speed & Heat Settings: Allows adjustment for different hair types and styles.
4. Cool Shot Button: Helps set hairstyles by releasing cool air.
5. Attachments: Some models come with diffusers (for curly hair) and concentrators (for precision styling).
6. Ionic & Ceramic Technology: Reduces frizz and prevents heat damage.
Uses of a Hair Dryer:
- Drying wet hair quickly.
- Styling hair (straightening, volumizing, curling).
- Setting hairstyles with different heat levels.
- Removing excess moisture before further hair treatments.
