A hair curling device includes a hair roller adapted to provide the hair wrapped and attached on it, and a sheath adapted for surrounding the hair roller. The hair roller includes a spiral groove formed on a side edge thereof, extending between first and second ends thereof and adapted for receiving the hair. Thus, the hair wrapped around and received in the groove is unable to slide with respect to the side edge of the hair roller, so that the hair curling device not only can save time but also can control the curvature of the hair easily.
