A hair dryer includes a housing, a fan unit, a heating element, a motor and a handle. The housing is the body of the hair dryer and has an inlet end and an outlet end. The motor rotates the housing relative to the handle in an oscillating manner. The fan unit is mounted in the housing so that air from vents at the inlet end pass through the fan unit to be blown out through the outlet end of the housing. As such, the housing moves without requiring any movement of the user's hand, wrist, or arm. The handle also has a controller for activating operation, adjusting speed, and setting temperature.
