A round brush is primarily used for creating volume in the hair. This type of brush features bristles that are arranged in a circular shape around a cylindrical core, allowing for the hair to be wrapped around the brush during styling. As heat is applied, typically from a hair dryer, the rounded shape of the brush lifts the hair at the roots, creating body and fullness.

While round brushes can also assist in creating soft curls or enhancing smoothness when used correctly, their main function is to give lift and volume, particularly at the roots. This makes them a staple in blow-drying techniques aimed at achieving bouncy, voluminous hairstyles. Smoothing can be accomplished with other types of brushes as well, which may be better suited for straightening or finishing a style without adding volume.

Understanding the specific purpose of a round brush is crucial for hairstyling, as it allows a stylist to choose the right tool for the desired outcome in volume and body.
