4. Round brush with metal barrel. The reason this is considered one of the best brushes for fine hair styling is that it directs hair away from the head, allowing warm air (from a blow dryer) to be concentrated on the roots. The metal barrel retains heat and helps reduce blow-drying time, which causes frizz. Rounded metal brushes are available in various sizes. Bigger brushes (e.g. 3.5â inches in diameter) are ideal for women with long hair. Smaller brushes measuring 1â to 1 Â½ brushes are optimal for shorter hair.
