What term describes the technique of using a comb and iron to create waves?

The technique referred to in the question is Marcel waving, which specifically involves the use of a comb and a heated curling iron to create uniform waves in the hair. This technique was named after its inventor, French hairstylist Marcel Grateau, who popularized it in the late 19th century. The process requires the stylist to manipulate the hair into a wave pattern while using heat to set the style, resulting in elegant, defined waves that are a classic look in hairstyling.

Chignon styling refers to a different method focused on creating an updo, typically involving twisting or pinning the hair into a bun at the nape of the neck. Braiding is a technique that interweaves strands of hair to create various styles but does not produce wave patterns like Marcel waving. Pin curling is a method of setting curls by rolling sections of hair and pinning them in place; while it can create waves, it does not use a comb and iron together in the same way. Marcel waving stands out because of its specific technique and desired outcome, making it the correct choice in this context.
