Claim 1
Independent Claim
159 words
Apparatus for maintaining a permanent wave upon hair growth without reprocessing previously waved end portions of hair, said apparatus comprising a generally cylindrical core for winding thereabout of a previously waved hair end portion, an enlarged closure on one end of said core, a cylindrical housing having one end open and the other end closed and formed with a longitudinal slot extending inwardly from said open housing end, said housing being internally sized to spacedly receive said core with said closure in closing engagement with said open end of said housing so that the core-wound previously waved hair is inside the housing and the next adjacent hair extends through said slot exteriorly of said housing for winding about said housing, and a seal on said housing for effectively sealing said slot with hair extending through said slot, whereby the externally housing-wound hair may be processed by soaking with solution while the core-wound hair is effectively sealed from the solution.
