What common tool is used to blend the hair and create volume?

The round brush is a common tool used in hairstyling to blend hair and create volume. When using a round brush in combination with a hair dryer, stylists can lift the hair at the roots, creating body and fullness. The shape of the round brush allows for a smoother finish while also curling the ends or adding a wave, depending on the styling technique used. This versatile tool is essential for achieving professional-looking blowouts and adds shape to various hairstyles.

While flat irons, combs, and hair dryers each serve important roles in hair styling, they do not specifically focus on adding volume and blending the hair in the same effective way a round brush does. Flat irons primarily straighten hair, combs are used mostly for detangling or parting, and hair dryers are essential for drying hair but require additional tools, like a round brush, to create the desired volume and blend.
