A curling iron is a heated styling tool used to create curls or waves in hair. It usually consists of a heated barrel and a clamp to hold the hair in place. Unlike rollers that curl hair passively, a curling iron uses direct heat to quickly shape the hair. Curling irons come in various sizes and barrel shapes, each creating different types of curls, from tight ringlets to loose waves. Think of it like a mini oven for your hair, carefully baking in the curl. Using a curling iron requires some practice to avoid burns and achieve the desired look.
