Citra has an appointment today with Holly, a client with straight, dark, shoulder-length hair. Holly has worn her hair this way for several years, and feels that it's time for a change. After discussing their options, Holly and Citra decide that the best choice for her is a permanent wave. During the client consultation, Citra discussed the different types of curls that they could achieve, and Holly decided that she would prefer curls that are tighter in the center and looser on the ends. With this in mind, which type of perm rod should Citra use when perming Holly's hair?
