"Layering in hair" is a hairstyling technique where hair is cut into layers of varying lengths, creating volume and texture. For instance, a popular layered hairstyle is the "Rachel" from the 1990s sitcom "Friends," characterized by its layered, shoulder-length cut.
Layered hair has gained relevance due to its ability to enhance any hair type, from straight to curly, by adding movement and bounce. It also helps reduce hair weight, making thick hair more manageable and fine hair appear fuller. Historically, the concept of layering in hair can be traced back to ancient Egyptian times, with depictions of layered hairstyles found in hieroglyphics.
