Abstract
A device to shape human hair whereby possibly pre-moistened hair is wound up in strands on curlers onto which a liquid or consistent permanent waving product is applied and processed with heat energy added to the hair curlers for a predetermined time. The permanent reshaping product is then rinsed and possibly after an additional treatment with liquid neutralizer and rinsing of the same, the curlers will be removed from the hair. After winding of the hair strands and application of the permanent waving preparation, the curlers are heated by a short-time application of energy to a predetermined temperature. The heat stored by the curlers will then be transferred from the curlers to the hair curls treated with the permanent waving preparation.
Claims14
A curling rod for heat processing waving solution applied to wrapped hair comprising:
- means for generating interior heat within said curling rod, the interiorly generated heat being transferred to an external surface of said curling rod;
- first contact members connected to opposing longitudinal ends of said means for generating interior heat;
- a manually operable power unit, said power unit including second contact members selectively engageable with said first contact members, respectively, for transmitting electrical power from said power unit to said means for generating interior heat, wherein heat processing of the waving solution applied to the wrapped hair is only from the external surface of said curling rod;
- and
- manually operable clamp arms electrically connected to said power unit, wherein said second contact members are disposed in distal ends of said clamp arms for selective engagement with said first contact members, respectively.
A method for shaping human hair comprising the sequentially ordered steps of:
- (a) pre-moistening and winding hair in strands on a plurality of curlers;
- (b) applying a perming preparation to the hair wound on curlers;
- (c) heating an internal heating element within each of said plurality of curlers for a predetermined time and to a predetermined temperature, thereby generating heat to an external surface of said plurality of curlers and causing a heat processing of the perming preparation;
- (d) rinsing said perming preparation from the hair wound on curlers;
- (e) neutralizing the hair wound on curlers with a neutralizing solution;
- and
- (f) removing the hair from each of said plurality of curlers.
