"Shoulder length haircuts for wavy hair" refers to hairstyles where hair falls around or just past the shoulders, specifically designed to complement and enhance wavy hair textures. An example is the "Rachel" cut, popularized in the 1990s, which featured layered, shoulder-length hair that accentuated natural waves.
These haircuts are popular due to their versatility, suitability for various face shapes, and ability to enhance the volume and definition of wavy hair. Historically, shoulder length haircuts can be traced back to the bobbed hairstyles of the 1920s, which were adapted to suit different hair textures.
