What is the primary use of a blow dryer in hairstyling?

The primary use of a blow dryer in hairstyling is to dry and style hair using heat and airflow. This tool combines heated air and the force of airflow to evaporate moisture from the hair, which is essential for achieving a dry and polished look. Additionally, the blow dryer allows for styling versatility—while drying the hair, it can also be used with various brushes to create different styles, such as smoothing, curling, or volumizing.

The blow dryer plays a fundamental role in the styling process as it not only removes moisture but also helps to shape and set the hair in the desired style. By adjusting the heat settings and airflow, stylists can cater to various hair types and textures, making it an indispensable tool in hairstyling.
