What kind of perm wrap is a bookend wrap?

A bookend wrap is characterized by the technique where one end of the hair section is folded over the perm rod. This method involves using a single piece of end paper, which helps to ensure that the ends of the hair are properly secured and protected during the perming process. By folding the hair over the rod in this manner, it allows for a more controlled and consistent curl formation, reducing the risk of frizz and unevenness.

The other types of wraps mentioned may involve different techniques that do not align with the specific characteristics of a bookend wrap, such as twisting hair multiple times or using both ends of the hair. The distinct feature of a bookend wrap is its simplicity and the focus on managing the ends of the hair for an effective curl.
