Abstract: A hair curling apparatus includes an adapter sleeve mounted to the end of the hot air delivery conduit of a hand-held hair dryer. A hot air delivery tube extends through the adapter sleeve and terminates in an apertured portion projecting forwardly of the sleeve. Rotatably mounted on the projecting portion is a circumferentially apertured and bristled hollow hair curling sleeve for effecting hair curling procedures. The hair curling sleeve includes a plurality of vanes in the interior thereof which react with the directed hot air flow through the apertured portion of the delivery tube to impart rotation to the hair curling sleeve. The adapter sleeve includes a manually operable valve for controlling the air flow through the delivery tube to the curling sleeve.
