The round brush is particularly effective for volume creation due to its design and how it interacts with hair when blow-drying or styling. When using a round brush, the stylist can lift the roots and wrap sections of hair around the brush, which allows the hair to be directed away from the scalp. This technique promotes lift and fullness at the roots, enhancing the overall volume of the hairstyle. The shape of the round brush also helps in creating soft curls or waves, depending on the technique applied, further contributing to a voluminous appearance.

In contrast, other tools serve different purposes. A straightening iron is primarily used for smoothing the hair, making it straighter and sleeker, which typically does not enhance volume. A curling wand is used to create curls or waves, but it might not effectively target root volume in the same way a round brush can. Clippers are designed for cutting hair and achieving uniform lengths rather than styling or volumizing. Thus, the round brush stands out as the optimal tool for adding volume to hairstyles.
