A hair dryer includes a casing having an air inlet and an air exit defining an exit plane. A motor driven fan propels air through the casing between the air inlet and exit. Plural wattage electric heating elements are disposed in a heater box in the casing for heating air to a selected temperature for discharge through the casing air exit. A thermostat, positioned downstream of the heating elements substantially centrally across the exit plane of the casing and disposed substantially in the exit plane, is connected in series circuit with at least some of the heating elements. The thermostat rapidly senses the air temperature at the air exit and disconnects the connected heating elements.
