Layer cutting is a hairdressing technique entailing segmenting the hair into various levels, producing a multifaceted and textured style. A prevalent example of layered long hair is the "Rachel" cut, popularized by Jennifer Aniston in the 1990s TV show "Friends."
Layering provides volume, movement, and shape to long hair. It can accommodate different face shapes and hair textures, reducing bulk and enhancing versatility. The technique has evolved from traditional blunt cuts to more graduated and blended styles.
