An improved permanent wave, mandrel device for hair, in which a small diameter rod forms a mandrel for rolling a tight curl of hair, the hair curl being pressed against the rods by an elastic cord stretched from one end of the rod to the other, and in which the improvement embodies the addition of a sponge member, preferably in the form of a cylinder surrounding the elastic cord and a portion of which is positioned between the cord and the curled hair to distribute the applied pressure more widely and prevents breakage of hair strands.
