LONG AND STRAIGHT
“The way Demi Moore wears her hair—really straight and long—softens square angles,” . And the center part “opens up the middle of her face, drawing attention away from the jawline.”
“Try waves from the ears down, which helps obscure any severity in the jawline,” Use a large round brush to smooth hair, then spritz on a wave spray like Sally HershbergerGlam Waves Texture Spray.
