The primary use of a curling iron is to create curls or waves in hair. This styling tool features a heated barrel that, when wrapped with hair, allows the heat to alter the hair's natural texture, setting it into a curled or wavy shape. The design of the curling iron is specifically intended for this purpose, making it a popular choice in hairstyling to enhance the overall look and provide variation in hairstyles.

While other styling tools and techniques may aim to straighten hair, add volume, or smooth out frizz, those functions are not the main intent of a curling iron. Straightening is typically achieved with flat irons, volume can be enhanced with specific styling products or techniques, and smoothing frizz often involves serums or blow-drying methods. Therefore, using a curling iron effectively focuses on achieving curls and waves, emphasizing its role in creating dynamic hairstyles.
