The best type of brush for blow drying is a round brush. Round brushes are specifically designed to create volume, curl, and smoothness in the hair while directing airflow from the blow dryer effectively. Their circular shape allows stylists to wrap sections of hair around the brush, which helps in achieving different styles—such as flips, waves, and curls—while also helping to distribute heat evenly.

In contrast, flat brushes are more suited for straightening hair and smoothing out tangles, as they do not provide the same volume or movement. Paddle brushes are used primarily for detangling, and they can be helpful for straightening hair as well, but they lack the ability to create lift and curl. Vent brushes, which have widely spaced bristles, are primarily used for quick drying and adding texture but do not allow for the same level of styling control that a round brush offers. Therefore, a round brush is the preferred choice for blow drying when aiming for a styled finish.
