Abstract
A hair-styling device serves to curl or wave hair. Said hair-styling device comprises two styling bodies 5, 5.1, which interact with each other to style the hair and can be rotated about the longitudinal axis of the styling bodies and of which at least one of the styling bodies 5, 5.1 is driven, which styling bodies 5, 5.1 have a shell surface contoured by elevations and recesses and are arranged in relation to each other in such a way that complementary contours of the two styling bodies 5, 5.1 mesh in the course of rotation of the two styling bodies. The styling bodies 5, 5.1 have a bone-shaped cross-sectional geometry having two head sections 7, 7.1 designed with a shell surface 8 that is convexly rounded at least in some sections and having a tapered central section 6 located between the head sections and designed with a concave shell surface. The radius of curvature in the region of the central apex 9 of the head sections 7, 7.1 of the one styling body 5, 5.1, 5.2 corresponds to the radius of curvature of the tapered central section 6 of the other styling body. The axis of rotation 11, 11.1 of the styling bodies (5, 5.1) is arranged in the central section 6 centrally between the central apexes 9 of the head sections 7, 7.1.
