Abstract
A diffuser for a hair dryer reduces the force of impact of air discharged from the hair dryer against the hair of a user. The diffuser includes a housing having an inlet port, an outlet port and a freely rotatable fan blade mounted within the housing. The inlet port is removably interconnected to the discharge nozzle of a hair dryer so that air discharged from the hair dryer enters the housing, strikes the fan, and causes it to rotate. The rotating fan disperses the discharged air into a plurality of diversely directed eddy currents which flow out of the outlet port. These less powerful eddy currents, which are applied to the hair of a user, will not upset the setting of hair. A screen can be interposed between the fan and the outlet port to prevent hair from becoming caught in the diffuser and to further disperse the eddy currents of air before they are discharged from the outlet port. Finger spacers can be mounted on the diffuser to keep the head of the user a predetermined distance away, and an adapter can be provided so that the size of the inlet port is adjustable to snugly receive different sized discharge nozzles of different hair dryers.
