An electric heating device includes a housing which forms a receiving pocket in which at least one PTC heating assembly with at least one PTC element received in a positioning frame and strip conductors electrically conductively connected to the PTC element for energizing the PTC element with different polarity is received. In order to compensate for manufacturing tolerances without significantly impairing the heat dissipation from the PTC element, at least one profile part is connected opposite main side surfaces of the PTC element in a heat-conducting manner. Outer main side surfaces of the profile parts opposite the PTC element are connected to an inner surface of the receiving pocket in a heat-conducting manner in each case. The profile parts are connected to the positioning frame.

Hairstyling devices include one or more heat transmissive elements having a coating disposed thereon, the coating having ceramic and lava rock incorporated therein. The use of lava rock-containing coatings as described herein results in hairstyling devices with heat transmissive elements exhibiting enhanced heat retention, faster heat recovery, and increased ion emission. Furthermore, lava rock-containing coatings have been found more durable than equivalent heat transmissive element coatings that do not have lava rock incorporated therein.
