Abstract: Device (1) for drying hair, comprising a hand-held unit (2) which is adapted to emit or discharge a flow of air to be directed onto the hair, characterized in that the hand-held unit (2) has a power source (18) which is arranged in a path (13) of the air flow to be emitted or discharged from the unit (2). In this way, heat or thermal energy that is generated in the power source (18) can be recovered or retrieved and transferred directly to the air flow in the device (1) so as to collect or scavenge waste heat from the power source.
