To create volume at the roots during styling, a round brush is essential because of its unique shape and design. When using a round brush, the bristles can grip the hair firmly while the circular form allows the stylist to lift the hair away from the scalp, which is crucial for achieving that desired lift and movement. As the hair is dried around the brush, the round shape helps to create curls and waves, which not only adds body but can also enhance the overall style with bounce.

In contrast, a flat iron is primarily used for straightening and smoothing hair rather than building volume. A paddle brush, while useful for detangling and smoothing out hair, lacks the curvature necessary to lift the roots effectively. A combing tool does not provide the volume-boosting capability that a round brush offers; it is generally used for sectioning or styling details rather than creating fullness at the roots.
