A hair styling brush with an internal heating element extends from a first end of a housing. A disk secured to the brush is rotationally mounted in an undercut groove adjacent the first housing end. A pinion gear secured by a threaded stud to an interior face of the disk engages a gear rack formed on a push button received for sliding movement within a transversely extending well within the housing. A first ring nut is threadedly engaged with the threaded stud. A coil spring has a first end loop connected to the first ring nut and a second end loop connected to a second ring nut secured adjacent a second opposite end of the housing. The second ring nut has a central longitudinal bore aligned with an aperture formed through the second housing end. A power cord extends sequentially through the second housing end, the second ring nut, the coil spring, the first ring nut, the pinion gear, the threaded stud, the disk and connects with the internal brush heating element. In an alternative construction, the coil spring may be replaced by a transversely extending compression coil spring which has a first end in abutment with a lower end of the push button and a second end in abutment with an interior housing surface.
