Short, layered cuts can be appropriate on round, long, square, oval and heart-shaped faces. The 2.25-inch rule is a measurement that helps determine if short hair can complement a person's face.
Master hairstylist John Frieda developed a formula for determining if short hair is flattering for different face shapes. The measurement involves aligning a ruler from just under the ear and down the face vertically. The second step is positioning a pencil under the chin and noting the distance indicated at its intersection with the ruler. If the measurement is under 2.25 inches, short hair can be flattering to that face shape.
A pixie is one example of a short, layered haircut. The hairstyle typically features side-swept bangs, a wispy perimeter and volume at the top. The pixie cut especially flatters round faces because it softens the roundness. The wisps also emphasize the cheekbones and eyes. Women with oval, square or heart-shaped faces can also wear the pixie.
Asymmetrical and edgy haircuts look good on women with oval faces. Asymmetrical haircuts are those that are longer on one side. Edgy haircuts often feature shaved sides or exaggerated length on top. Both feature short layers.
Women with long faces typically need longer layers that add volume to the sides rather than the front. These types of styles add width to a narrow face.
