The correct answer is the croquignole method, which is one of the two fundamental techniques used for wrapping hair around perm rods. This method involves wrapping the hair from the ends to the scalp in overlapping layers, creating a tighter curl near the scalp and a looser curl at the ends. This technique is particularly effective for creating defined curls and volume, as the tighter wrapping at the scalp provides added lift.

The other methods listed, such as the halo method, cascade method, and zigzag method, do not specifically correspond to well-established techniques for perming hair. The croquignole method’s ability to create different curl patterns and its versatility make it a staple technique in the field of cosmetology, particularly in perming practices. Understanding the distinct characteristics and applications of the croquignole method enhances a stylist's skill set when it comes to achieving desired results in hairstyling.
