Layered haircuts involve cutting hair at different lengths to create texture and volume. This technique allows for movement and can enhance the natural shape of the hair. Layers can be added to various hair types, including straight, wavy, and curly, making it a versatile choice for many. The benefits of layered haircuts include reducing bulk in thick hair and adding body to fine hair. They can also frame the face, highlighting features. Popular styles include the shag, long layers, and bob, each offering a unique look while maintaining the layered effect.
