KIM KARDASHIAN’S STYLE: Gradual layers that start at the chin. WHAT MAKES IT HOT: “If your hair is this long, keeping it a single length can look like a flat sheet of hair. These long, uniform layers give the style a luxe, controlled movement,” says Townsend. WHO IT WORKS FOR: “This cut is best for someone with lots of thick hair, be it natural or extensions. Fine hair can look straggly with too many layers,” he says.
