ABSTRACT OF THE DISCLOSURE The invention relates to hair rollers and provides for the use of a cylindrical tube rolled from a rectangular sheet of flexible material, the sheet having an outer edge which overlaps a portion of the tube. The tube has a pair of opposing transverse edges, each of which is engaged within a spiral groove formed in opposing caps. The caps are rotationally mounted on an elongated shaft, such that rotation of the disks causes advancement of the transverse edges within the spiral groove, changing the diameter of the outer tube, as desired.
