What is the benefit of using a round brush when blow-drying?

Using a round brush during blow-drying has several advantages, with the primary benefit being the addition of curl and volume to the hair. When a round brush is used, it allows the stylist to wrap sections of hair around the brush while blow-drying, which creates tension and shapes the hair as it dries. This technique enables the formation of soft curls, waves, or added body at the roots, resulting in a more voluminous and styled look.

The unique shape of the round brush helps lift the hair away from the scalp, promoting volume and achieving a bouncy look. The size of the brush can also affect the tightness of the curl or the amount of volume created; smaller brushes can create tighter curls, while larger brushes may provide more of a loose wave.

While other options such as straightening hair, improving shine, and reducing drying time are aspects of hair styling that can be influenced by blow-drying techniques and tools, they do not directly highlight the ability of a round brush to create curls and volume, making the first choice the most relevant to the specific question asked.
