During a perm, what is necessary for end papers to prevent fish hooks?

Using end papers that extend beyond the ends of the hair is essential during a perming process to prevent fish hooks. Fish hooks refer to the undesirable, bent ends of the hair that can occur when the hair is not properly wrapped or supported during the curling process. By ensuring that the end papers extend beyond the ends of the hair, you provide adequate support and coverage for the ends. This promotes a smoother, more uniform curl and reduces the risk of the hair snagging or crimping at the ends.

The other options do not adequately support proper wrapping and curling techniques. For instance, laying end papers flat may not provide enough coverage for the ends, leading to the fish hook effect. Cutting end papers to the same length as the hair would not allow for extra support needed to maintain a uniform curl. Being thicker than the hair strands could also inhibit the curling process rather than facilitating it, as thicker materials may not mold as effectively to the shape of the curl. Therefore, extending the end papers beyond the hair ends is the best practice to ensure a successful perm outcome.
