Using a round brush during blow-drying is primarily intended to add curls and volume to the hair. The unique shape of the round brush allows for the hair to be wrapped around it as heat is applied, creating tension and enabling the stylist to shape the hair into curls or waves. This technique also lifts the roots of the hair, contributing to added volume, which is often desired in various hairstyles.

When utilizing a round brush, it's common for stylists to rotate the brush while blow-drying to further enhance curl formation and volume. The combination of the brush's shape and the heat from the blow dryer allows for effective styling, making it a go-to tool for achieving bouncy, voluminous looks.

The other choices do not encompass the primary reason for using a round brush effectively. While straightening hair can be achieved with a round brush, it is not its primary function. Similarly, creating a slicked-back style is more commonly associated with flat brushes or combs. Decreasing drying time is not a direct effect of using a round brush; rather, it's more related to the power of the blow dryer and technique used.
