What is the primary benefit of using a round brush during styling?

Using a round brush during styling is primarily beneficial for adding volume to the hair. The circular shape of the brush allows for lift at the roots and encourages the hair to have a more rounded, full appearance as it is styled. When the hair is wrapped around the brush, the heat from the blow dryer or styling tool helps create shape, enhancing the natural bounce and movement. This technique is particularly effective for achieving a voluminous blowout look, making the hair appear thicker and more dynamic.

While a round brush can also help reduce frizz, create curls, or assist in straightening hair, its primary function is volume enhancement. The way hair is wrapped around the brush, combined with the heat, promotes the desired lift and fullness that many people seek in their hairstyles.
