Abstract: An electrically heated hair curling brush for drying and styling hair includes an elongated handle having a longitudinal axis and provided at its front end with an axially extending inner tube affixed non-rotatably to the handle. An outer tube formed with a multiplicity of radial teeth defining a hair brush is engaged over the inner tube and supported for rotation about the longitudinal axis thereof by cooperating formations on the tube and handle. The cooperating formations include a circumferential rim on the front end of the handle defining a groove receiving and engaging a radially extending circumferential flange on the end of the outer tube adjacent the handle. A locking arrangement, including a radially displaceable spring-biased detent on the handle movable into engagement between radial locking teeth on the flange, is provided for selectively preventing rotation of the outer tube on the inner tube.
