The primary function of a blow dryer in hairstyling is to dry hair effectively while also allowing the stylist to alter its shape or texture. When blow drying, the heat from the dryer interacts with the hair, helping to evaporate moisture while simultaneously reshaping and styling the hair. This process can enhance natural curls, create waves, or provide a smooth finish, depending on the technique used.

Using a blow dryer allows stylists to manipulate the hair more freely. For instance, by positioning the nozzle downward and directing the airflow along the hair shaft, stylists can create a sleeker appearance. Conversely, if the airflow is directed from underneath the hair, it can add volume and lift at the roots.

While other options do involve different aspects of hairstyling, they do not encapsulate the blow dryer's primary role as well as the ability to both dry and shape the hair. Setting hair with mousse or adding volume through styling products can be part of the hairstyling process, but they focus on additional steps rather than the fundamental function of a blow dryer. Similarly, while a blow dryer can assist in straightening hair, that is just one of many outcomes achievable with its use and not the sole purpose of the tool.
