Abstract: An eyelash perm rod for use in eyelash perking in which lashes bent upward to form a curled state are temporarily stuck onto the rod and a permanent wave lotion is applied thereto for producing permanent-treated, curled eyelashes. The eyelash perm rod of the invention has a solid body having an eyelash-setting surface which is a curved surface and an eyelid contact surface which is a flat surface. The solid body has a wing-shaped cross section, wherein a first portion of the area at which the eyelash-setting surface meets the eyelid contact surface is thin, and a second portion which is opposite to the first portion is thick.
