Shoulder-length hair best suits those who have an oval or long face. Shoulder-length hair that is styled properly is also suitable for people with square faces.
Oval faces are slightly longer than they are wide and present a slightly rounded jaw line. People with oval shaped faces can wear any length hair and style, including shoulder-length hair. For those with long faces, shoulder-length hair is the most flattering cut because it creates the illusion of width in the face. Additionally, long faces benefit from bangs, which help shorten the appearance of the face by covering the forehead. For square-shaped faces, shoulder-length hair styled to look soft and voluminous is suitable.
People with round faces should avoid short hair and instead opt for a longer, layered hair style. This creates the illusion of angles in the face. Heart-shaped faces also benefit from longer hair with soft layers that open up the shape of the face.
