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.
