A hair roller is provided around which hair can be wound easily with tension toward the outside acting on the hair, without a fear that the distal ends of the hair are folded, with ease in handling, and with good operativity, and with which the wound state can be maintained, regardless of the level of skill, i.e., even by a beautician who lacks experience or an amateur. A hair roller comprises a rod having a hair winding portion where at least a portion around which hair is wound is resiliently restitutively compressed and deformed and also having a hair distal end retaining means for retaining distal ends of hair and a wind maintaining means for maintaining the state of hair wound around the rod with tension.
