Adding a deep side part is such an easy move for any hair length or texture because it slims out the face (No need to join in on the middle part fad!).
Avoid anything too full in the middle, and instead, shoot for loose, casual, and even messy waves for the best effect.
Whether your hair is styled up, down, straight, or curly, adding visual interest and height at the root will draw the eye up and away from the fullest part of the face.
Women who wish to camouflage a full face should not do low or even mid-height ponytails as these will only bring more attention to a round-shaped face.
