Final answer:
The partings for a perm rod can be horizontal, vertical, or diagonal, and are chosen based on the desired perm outcome and natural fall of the curls.
Step-by-step explanation:
The partings for an individual perm rod can be horizontal partings, vertical partings, or diagonal partings. The choice of parting depends on the desired outcome of the perm. For instance, horizontal partings can create a more traditional look with more volume at the roots, vertical partings can create a more dropped curl effect, and diagonal partings can give a more natural look with softer lines and transitions. It is important for a stylist to choose the parting based on the client's hair type, the desired final style, and how the curls fall naturally.
