Abstract
An improved hair roller is disclosed which is adapted to be stored in a substantially flat configuration and to be expanded into a body having a cylindrically shaped configuration which is substantially resistant to bending and buckling. The hair roller comprises first and second sleeve shaped bodies, one of which is dimensioned to be telescopically positioned within the other and the bodies are adapted to be mutually rotated for forming and maintaining a cylindrically shaped configuration.
