  • Device for the shaping of human hair
    Patent number: 5174311
    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.
