How do some round brushes enhance curls with the help of a blowdryer?

1. By using softer bristles

2. With a metal cylinder base to transfer heat

3. Through a built-in electric heater

4. By rotating automatically

The correct answer is: With a metal cylinder base to transfer heat

Some round brushes enhance curls with the help of a blowdryer using a metal cylinder base to transfer heat. This allows the brush to heat up and help curl and shape the hair while also speeding up the drying process. Option A, using softer bristles, would not directly enhance curls but may be more gentle on the hair. Option C, through a built-in electric heater, is incorrect as most round brushes do not have a built-in heater. Option D, by rotating automatically, may help with curling the hair but does not necessarily enhance the curls. Therefore, option B is the most accurate answer.
