A cool air hair curler is a hair styling tool that uses cool air to curl hair. It is a gentler alternative to traditional hair curlers, which use heat to curl hair. Cool air hair curlers are often used by people with fine or damaged hair, as they are less likely to cause damage.
Cool air hair curlers come in a variety of shapes and sizes. Some are small and handheld, while others are larger and stand on a counter. They typically have a rotating barrel that heats up and curls the hair. Cool air hair curlers also typically have a cool air setting, which helps to set the curls and prevent them from falling out.
