How should perm rods be placed in the hair?

The correct approach to placing perm rods in the hair is rolling them evenly to ensure uniform curl formation. When perm rods are applied with consistent tension and methodical placement, it allows for a more predictable and consistent set of curls. This uniformity is crucial because it ultimately affects the overall shape and style, leading to a polished and professional look once the perm is complete.

If the rods are not rolled evenly, as suggested in other options, it could result in uneven curl sizes or inconsistent texture throughout the hair. This would not only compromise the desired outcome but could also lead to dissatisfaction for clients who expect a particular look. Maintaining even tension and placement is also essential for ensuring that the perm solution works effectively on each section of hair, contributing to the longevity and overall health of the curls formed.
