What are the two basic types of wrapping hair around a perm rod?

The correct answer identifies the two primary techniques used for wrapping hair around a perm rod: the croquignole perm wrap and the spiral wrap.

In the croquignole perm wrap technique, the hair is wrapped in a way that the ends of the hair strands are wrapped first, usually from the ends toward the scalp. This method tends to produce more volume at the roots, and the resulting curls are tight and well-defined.

On the other hand, the spiral wrap involves wrapping the hair at an angle around the rod, creating a spiral effect from the scalp to the ends. This technique leads to a more elongated curl pattern, which can give a different styling effect compared to the croquignole method.

Understanding these two fundamental techniques is essential for stylists because they allow for varied results in perming, which can cater to different client preferences and desired outcomes in hair texture and volume.
