A 3 barrel curling iron is a hairstyling tool used to create loose, beachy waves or tight, defined curls. It consists of three barrels that are heated and clamped together to style hair.
3 barrel curling irons are popular because they can create a variety of looks, from soft, natural waves to glamorous, bouncy curls. They are also relatively easy to use, making them a good choice for both beginners and experienced hairstylists.
