Abstract: An attachment for a hair dryer includes an upper body for supporting a heat transmissive plate with a comb extending from one side of the heat transmissive plate and a lower body for attachment to an outlet of the hair dryer. The heat transmissive plate is heated by the hot air exiting the hair dryer's outlet. The upper body of the attachment includes vents positioned about the heat transmissive plate for directing heated air generally in front of and behind the heat transmissive plate, and a pair of side vents for directing heated air to the sides of the heat transmissive plate. The lower body of the attachment may include a plurality of inner ribs positioned at its internal surface or a plurality of flexible inner segments situated within the internal surface, either of which serve to attach the lower body to the hair dryer outlet. The hair dryer attachment thus provides a simple means for using a hair dryer to dry and straighten one's hair.
