Abstract: An air diffuser for attachment to a hair dryer, with a housing containing an air inlet, a hood, and an air outlet from the hood, a face plate having a front side and a rear side and being pivotally mounted in the air outlet so that alternately one or the other of the sides can face outwardly. The face plate has air orifices passing through it and presents a different pattern of orifices on the two sides. One side has fingers mounted extending from it, the fingers including an air passages running within the fingers and through to the other side. That side also has a skirt along its periphery. As a result, the air diffuser provides for a different air diffusion pattern when the front side faces outwardly than when the rear side faces outwardly.
