The purpose of using a curling iron is to create curls or waves in the hair. The device works by applying heat to sections of hair, which alters the hair's structure temporarily and allows for the formation of curls or waves. When the hair is wrapped around the heated barrel of the curling iron, the heat penetrates the hair shaft, making it pliable and enabling it to hold the desired shape once released. This technique is popular for achieving defined curls, soft waves, or even beachy styles, depending on how the curling iron is used.

Other choices relate to different hair styling techniques that are typically achieved with other tools or methods. For instance, straightening hair usually requires a flat iron, adding volume might involve techniques like backcombing or using a round brush with a blow dryer, and frizz removal generally involves using smoothing products or specific styling techniques. Each option represents a distinct styling goal that requires different approaches or tools, highlighting the specific function of a curling iron in the overall realm of hair styling.
