The process that adds volume to hair using heat is known as thermal styling. This technique involves using heat tools such as blow dryers, curling irons, or flat irons to manipulate the hair. When heat is applied, it temporarily alters the structure of the hair, allowing it to be shaped into styles that create volume and movement.

Thermal styling can enhance the natural texture of hair, giving it lift and body. It's an effective method for achieving voluminous looks, especially for those with fine or limp hair. The heat can help create curls, waves, and other styles that contribute to a fuller appearance.

Other options do not specifically focus on adding volume with the use of heat. Scalp treatment pertains to care and health of the scalp; deep conditioning is aimed at improving hair health and moisture rather than styling; and while curling does involve using heat, it is a specific way to style hair rather than a broader category like thermal styling that encompasses various techniques for adding volume.
