The technique used to enhance curl in hair during a perm is wrapping the hair around rods. This method is essential because it allows the hair to take on the shape of the rod as the perm solution is applied. The size of the rod chosen will determine the size of the curl. Smaller rods create tighter curls, while larger rods produce looser waves. The chemical process involved in perming breaks down the hair's internal bonds, allowing the hair to mold to the shape of the rod as it is wrapped.

While slicing the hair can be a useful technique in cutting and texturizing, it does not contribute to curling during the perm process. Curling with a flat iron is a styling technique that is done after the hair has been treated but is not part of the perming process itself. Blow drying the hair may help in styling or finishing touches but does not alter the hair's structure to create curls as achieved through the perm application. Thus, wrapping hair around rods directly accomplishes the goal of enhancing curl.
