Marcelling is a hairstyle technique that was popular in the 1920s. It involves creating uniform, deep waves in the hair using a hot iron. While this hairstyle has become outdated, there are various synonyms for the word marcelling that may still be in-use today. These include "sculpting," "texturizing," "wave making," "hair waving," and "wave setting." Each of these phrases describes a process of creating defined waves or texture in the hair using different methods such as curling irons, hair rollers, and braiding. These terms are still relevant in the world of hairstyling even though marcelling is no longer fashionable.
