A curl iron for hair, also known as a curling iron or hair curler, is a heated styling tool used to create curls, waves, or ringlets in hair. It typically consists of a cylindrical barrel that heats up and a clamp that holds the hair in place while it curls.
Curl irons are a popular hair styling tool that has been used for centuries. They offer a variety of benefits, including the ability to create different types of curls, add volume, and reduce frizz. One of the key historical developments in the evolution of curl irons was the invention of the electric curling iron in the early 20th century.
