Abstract: A hair treatment device characterized by a generally cylindrically shaped, hollow tension roller having a plurality of slots provided in spaced relationship along the longitudinal axis in the outside wall of the tension roller, and a securing means cooperating with the tension roller for securing the tension roller on the head and tensioning strands of hair wound on the roller for chemical treatment. In a preferred embodiment of the invention the securing means is characterized by a tension pin provided with a cooperating elastic cord and a hook attached to the free end of the cord for adjustably applying tension on a segment of hair wound on the roller for the purpose of treating the hair strands and setting the hair.

Abstract: A hair treatment device characterized by a round, partitioned rod having, in a preferred embodiment, a post on one end and a partition between the post and the opposite end, the post, partition and rod each having a plurality of staggered apertures for securing the device in place with pins. The rod may be provided with a single partition in another embodiment of the invention, and the partitioned design permits a length or tress of hair to be wound on the device and treated simultaneously with separate treating solutions and no comingling of the solutions. The device may also be provided with grooves traversing the partition and rod to accommodate the hair strands or tresses and effect more uniform curling.

Abstract: A hair treatment device characterized by a generally cylindrically shaped, hollow tension roller having a plurality of apertures in the wall thereof, and a securing means cooperating with the tension roller for securing the tension roller and strands of hair wound on the tension roller; the tension roller and hair strands rolled thereon are subjected to a selected degree of tension for the purpose of removing curl in the hair strands and setting the hair.
