The primary purpose of using a blow dryer in hairstyling is to speed up the drying process. When wet hair is exposed to the heat and airflow generated by a blow dryer, it evaporates moisture more quickly than air drying alone. This is particularly important in professional settings where efficiency and client turnaround time matter. By utilizing a blow dryer, stylists can ensure the hair dries thoroughly before moving on to other styling techniques, which can help maintain the overall style and appearance.

While the other options highlight effects that can be achieved with a blow dryer, the basic function revolves around drying hair rapidly. Setting hair in place, creating volume, and enhancing hair color can all be secondary effects of blow-drying, especially when used in conjunction with styling products or techniques, but they are not the main objective of the tool itself.
