The primary use of a blow dryer in hairstyling is to dry hair and create volume and style. When drying hair, the heat from the blow dryer evaporates moisture and speeds up the drying process, allowing for styling to take place more quickly. Additionally, using a blow dryer can enhance the shape, volume, and texture of the hair through various techniques, such as directing airflow with a brush or using diffusers. The versatility of blow dryers enables hairstylists to achieve a variety of looks and styles, making them an essential tool in the hairstyling process.

Other options, such as straightening hair completely or enhancing color, involve more specific techniques or tools and are not the primary functions of a blow dryer. Similarly, while you can achieve curls with a blow dryer, this would typically involve additional tools or techniques, making it less relevant than the basic drying and volumizing role of the blow dryer.
