8. The hair styling apparatus of claim 1 , further comprising a plurality of retaining elements.

9. The hair styling apparatus of claim 8 , wherein the rotating member defines a peripheral region, and the plurality of retaining elements are spaced apart at the peripheral region.

10. The hair styling apparatus of claim 1 , further comprising one or more retaining elements, wherein the one or more retaining elements extend along less than an entire longitudinal length of the hair styling surface.

11. The hair styling apparatus of claim 1 , further comprising a heater inside the barrel to heat the barrel.

12. The hair styling apparatus of claim 11 , wherein the heater is selected from the group consisting of a positive temperature coefficient heater having a function of preventing overheating, an alumina ceramics heater, and heat wave coils.

13. The hair styling apparatus of claim 1 , further comprising a motor configured to rotate the rotating member in opposite rotational directions, wherein the rotating member is rotated around the hair styling surface in response to a directional input from the user.

14. The hair styling apparatus of claim 1 , wherein the rotating member further comprises an upper surface through which the heated barrel extends, and the retaining tab extends from the upper surface of the rotating member.

15. The hair styling apparatus of claim 1 , further comprising another retaining tab and a plurality of retaining elements,

wherein the upper end of the rotating member comprises an upper surface,

wherein the retaining tab and the another retaining tab extend from the upper surface of the rotating member,

wherein the plurality of retaining elements are distributed evenly around the rotating member, and

wherein the lower end of the rotating member comprises a hair loading region comprising a tapered portion that increases in width as it leads into the plurality of retaining elements.

16. A method of using a hair styling device, comprising:

positioning the hair styling device in proximity to a user's head, the hair styling device comprising:

a heated barrel defining a hair styling surface and a central axis; and

a rotating member disposed at an end of the hair styling surface and configured to rotate with respect to the heated barrel about the central axis of the heated barrel, the rotating member comprising a retaining tab that is configured to retain the hair and wind the hair around the hair styling surface, the retaining tab extending along a direction of the central axis of the heated barrel,

wherein, in an at-rest position, the retaining tab is spaced apart from an entire length of the heated barrel without being held in place by a user,

wherein the rotating member forms an outer surface of the hair styling device,

wherein the outer surface of the hair styling apparatus comprises a lower portion comprising a handle of the hair styling apparatus and an upper portion comprising the heated barrel,

wherein the rotating member is hollow and comprises an upper end and a lower end, and the handle extends beyond a bottom edge of the rotating member at the lower end and the heated barrel extends beyond a top edge of the rotating member at the upper end, and

wherein the hair styling surface rotates with respect to the handle and about the central axis of the heated barrel;

retaining hair attached to the user's head within the rotating member of the hair styling device; and

wrapping the retained hair around the hair styling surface to impart a curl in the hair by rotating the rotating member around the hair styling surface to wind the hair around the hair styling surface.

17. The method of claim 16 , wherein a thermal safety tip is mounted on a free end of the hair styling surface.

18. The method of claim 16 , wherein the hair styling device further comprises one or more retaining elements, and the one or more retaining elements extend along less than an entire longitudinal length of the hair styling surface.
