"Long wavy hair layered" refers to a hairstyle composed of long, flowing hair styled in loose, cascading waves with a stacked, graduated cut. A prime example is the iconic beach waves sported by surfer girls, where the hair is naturally curled by the ocean water and wind and falls in loose, layered sections.
This hairstyle is highly sought after for its flattering and versatile nature, as it suits most face shapes and hair textures, enhancing volume and creating a dynamic, textured look. Its popularity can be traced back to the 1970s when Farrah Fawcett's feathered hair became a cultural phenomenon.
