Wrapping the hair around permanent wave rods requires applying tension to ensure that the hair is securely wrapped and the curls or waves have a uniform shape. Smoothness and winding refer to the technique of wrapping the hair smoothly and tightly around the rods, which is important for achieving a desired result, but they are not the absolute minimum requirement. Softening is also a technique used to relax the hair and make it easier to wrap, but it is not the minimum requirement for wrapping the hair around permanent wave rods. Overall, tension is essential for successful permanent wave results.
