What is a "curling iron"?

A curling iron is a heated styling tool designed to create curls or waves in the hair. It typically consists of a cylindrical barrel that heats up when plugged in. The user wraps a section of hair around the barrel and holds it for a few seconds to create the desired curl. Curling irons come in various sizes, allowing for different curling effects, from loose waves to tight curls. They are a popular tool for achieving versatile and glamorous hairstyles, offering individuals the ability to transform their hair texture and add volume and definition to their locks.
