Abstract
A hair roller is described which is adapted to be expanded from a substantially flat configuration into an elongated, cylindrically shaped body which is substantially resistant to bending and buckling. The hair roller comprises first and second generally planar, flexible roller members which are hinge coupled for enabling resilient deflection of the members into a body having a generally cylindrically shaped configuration. A fastening means is provided for maintaining the body in the deflected, cylindrically shaped configuration.
