A hand-held hair dryer has a housing that consists of a handle (12) and of an outer tube (14) through which air can flow. The outer tube (14) has an air flow inlet (16) and an air flow outlet (18) and means for generating and heating the air flow are provided in the housing. An inner tube (42) that receives at least the means for heating the air flow is arranged inside the outer tube (14). The inner tube (42) is made of a material with a higher thermal resistance than the outer tube and ends at least at the level of the outlet of the outer tube (14) or extends beyond the outlet of the outer tube (14) in the flow direction (64). A hair styling tool, for example a nozzle (44), a diffuser or the like, can be secured to the inner tube (42).read more
