Which type of brush is NOT typically used for blowdrying?

A teasing brush is primarily designed for creating volume and texture in the hair, often by separating the hair shafts and backcombing. This type of brush is specifically suited for styling techniques that involve adding lift and body rather than for drying the hair.

In contrast, round brushes are excellent for creating curls and waves during blowdrying, as they can grip the hair and give it shape while the heat is applied. Vent brushes, with their open design that allows for airflow, help speed up the drying process, making them ideal for blowdrying. Flat brushes can also be used during blowdrying to create smoothness and straightness.

Therefore, the teasing brush is distinct in its intended use and functionality, making it not suitable for blowdrying compared to the other types of brushes mentioned.
