The most flattering hairstyles for square faces are… ones that play down the strong, angular jaw line. Add texture with curls, layers that start at the jaw line or choppy bangs to soften the strong lines of your jaw. Anything long and sleek will also flatter. And, if your hair is curly, play up your waves like Salma Hayek to balance out the boxiness.
Avoid…One-length bob hairstyles (especially chin-length) and blunt bangs both of which will only draw attention to an already-broad forehead and chin.
Celebrities with a square face are… Gwyneth Paltrow, Demi Moore, Angelina Jolie, Isabella Rosellini, Rosario Dawson
