A curling iron includes a steam generator, a heating unit, a condensed water discharging unit, and a check valve. The steam generator is configured to generate steam using water. The heating unit is configured to receive steam from the steam generator and transfer heat of the steam to a target material. The condensed water discharging unit is configured to collect condensed water from the heating unit and to return the condensed water to the steam generator for recycling the condensed water, and the condensed water discharging unit is disposed between the heating unit and the steam generator. The check valve is configured to prevent the steam in the heating unit to flow into the steam generator and to allow the condensed water in the heating unit to flow into the steam generator, and the check valve is disposed between the condensed water discharging unit and the steam generator.
