<p>A hair dryer attachment includes a rotor impeller (7, 9, 10; 107, 109, 131, 132) for converting a uniform stream of air from the hair dryer into a pulsating stream of air. A governor (11, 12, 13, 14; 111, 112, 113, 114) is provided on the rotor impeller (7, 9, 10; 107, 109, 131, 132) or reduction gearing (135, 136) is provided between the rotor (107, 109) and the impeller (131, 132) to reduce the speed of rotation so that the pulsations are at a frequency perceptible to the user. <IMAGE></p> |
