Abstract
The air nozzle attachment (8) for the hair dryer (2) is connectable to the blower opening (7) of the hair dryer and produces a hot-air stream (9) and a cold-air stream (10) that are arranged side-by-side. The air nozzle attachment (8) has a hot-air nozzle (13) and a cold-air nozzle (14) located side-by-side and, on an end connectable to the blower opening (7), has a central conduit entrance (11) and a coaxial conduit entrance (12), which open into the hot-air nozzle (13) and the cold-air nozzle (14) respectively. The air nozzle attachment (8) can be detached again from the dryer (2) and preferably has a snap-on coupling device (18) for connecting the air nozzle attachment to the dryer (2), which permits rotation of the air nozzle attachment.
