A hair styling iron includes a handle (14) to which a heated barrel (16) is mounted, a motorized means (12) for moving the barrel (16), a control circuit, and a drive switch that can be actuated by the user. The drive switch is connected to the control circuit controlling operation of the motorized means (12). The control circuit including a timer monitors at least one change of state of the drive switch to determine a starting time, and actuates an alarm or a response, such as a reversal of the motorized means (12) to unwind the hair, after an elapsed time measured from the starting time. The elapsed time may be user-selected or calculated automatically depending upon the length of hair wound onto the barrel (16), with compensation for barrel (16) temperature. |
