A three barrel curling iron is a hair styling tool used to create waves or curls in hair. It consists of three heated barrels that are typically made of ceramic or tourmaline. The barrels are arranged in a triangular shape, with the middle barrel being slightly wider than the outer two.
Three barrel curling irons are becoming increasingly popular because they can create a variety of different looks, from loose, beachy waves to tight, bouncy curls. They are also relatively easy to use, even for beginners. To use a three barrel curling iron, simply clamp the hair between the barrels and hold for a few seconds. The heat from the barrels will create waves or curls in the hair.
