The invention relates to a curling iron that consists of a tubular heating rod and a heating element extending in the longitudinal direction of the heating rod. The curling iron further comprises a fuel container for receiving and dispensing a liquid fuel, and a valve device for gasifying and regulating the fuel. The heating element is controlled depending on the temperature by a thermostat disposed in the vicinity of the heating element. According to the inventive curling iron, the thermostat is thermally shielded from the heating element by a separation wall, thereby allowing to better control the temperature behavior of the heating rod and to prevent excessive temperature peaks.
