Abstract: A device for styling hair includes a wand defining a handle grip surface and a first styling surface spaced from the handle grip surface and a plate defining a second styling surface, the plate being pivotally coupled to the wand to clamp the hair between the first styling surface and the second styling surface. The device further includes a heating element in thermal communication with the first styling surface or the second styling surface to transfer heat to the hair via the first styling surface or the second styling surface, respectively, and an ultrasonic transducer configured to generate ultrasonic vibrations. The ultrasonic transducer includes a horn in contact with the wand or the plate to transmit the ultrasonic vibrations to the hair via the first styling surface or the second styling surface, respectively.

Abstract: An adjustable barrel, a barrel-adjustment assembly, and an adjustable distal tip assembly. The barrel is radially adjustable between an expanded position and a contracted position having different diameters. The barrel-adjustment assembly includes a barrel cam, a gear-set, and a rotary adjustment ring. The barrel cam rotates to unwrap and wrap the barrel thereabout between the expanded and contracted positions. The gear-set rotationally drives the barrel cam. The adjustment ring can be longitudinally translated from a disengaged position to an engaged position. In the disengaged position the gear-set is disengaged (but an anti-rotation assembly is engaged) and in the engaged position the gear-set is engaged (and the anti-rotation assembly is disengaged). Once in the disengaged position, the adjustment ring can be rotated, which causes the engaged gear-set to rotate the barrel cam, which in turn wraps and unwraps the barrel about the cam into increased or decreased diameters.
