A round brush is most suitable for blow-drying hair because of its design and structure, which allows for versatile styling and volume creation. The cylindrical shape of the brush helps to lift the hair at the roots while directing the airflow from the blow dryer along the hair shaft. This combination promotes better curl, wave, or smoothness, depending on the technique used.

Furthermore, round brushes come in various sizes, allowing stylists to choose the ideal brush for different hair lengths and styles. Smaller round brushes can create tighter curls, while larger ones can enhance volume and fullness in longer hair.

The other brushes serve different purposes; for example, wide-tooth combs are mainly used for detangling wet hair without causing breakage, flat paddle brushes are effective for straightening and smoothing but lack the capability to create volume or curls when blow-drying, and vent brushes are designed for quick drying and airflow but do not give the same level of control and style that round brushes provide. Overall, the round brush's ability to shape, smooth, and add volume makes it the go-to tool for blow-drying hair.
