A hair dryer includes a casing inside which a heat generation device for generation of heat by burning fossil fuel supplied from a removable internal fuel container and a fan for generation of an air flow passing through the heat generation device to be heated thereby for the provision of heated air stream are arranged. The heat generation device includes a cordierite based ceramic body on which a platinum based oxidation catalyst is coated. An initial ignition device is provided to cause an initial burning of the fuel supplied to thereto for heating the catalyst to the working temperature thereof. Once reaching the working temperature, the catalyst itself maintains the oxidation or burning of the fuel in a flameless manner and the heated air flow is continuously supplied until the fuel supply is cut off and the fan turned off.
