A vent brush or round brush is optimal for blow-drying straight hair because these types of brushes are specifically designed to allow hot air from the blow dryer to pass through the bristles, which speeds up drying time. The vent brush has openings in its design that facilitate airflow, preventing excessive heat buildup and helping to achieve a smooth finish. In contrast, round brushes can add volume and help you create curls or waves, while also smoothing the hair as you dry it, making them versatile for various styling techniques.

On the other hand, a paddle brush is best suited for detangling and smoothing hair rather than for blow-drying, as it doesn’t allow for much airflow. A flat brush is similar in its limitations and is used more for straightening and smoothing already dry hair rather than for the blow-drying process. Lastly, a wide-tooth comb is primarily used for detangling wet hair and would not be effective for styling during the heat application process involved in blow-drying. This makes the vent or round brush the ideal choice for achieving a polished, straight look when blow-drying hair.
