Some hairstyles make your face look thinner, while others make it look rounder. Hook yourself with a hairstyle that works to make your face look thinner. For instance, if you have a round face, then you should think about maintaining long hair. Go for layered bangs that would help to make your face look slender. If you want a short hairstyle, then you can go for bob cut with razored ends. Apart from these, even highlights can help to create a vertical line on your face that makes your face look longer and slim.
