19. Sweet Bob with Deep Side Part, Bangs, and Violet Coloring

If this post were a style master class, this look would get an A+. It’s doing so many things right when it comes to helping thin hair appear thicker: it’s nailing the deep side part, the short length, the blunt bob style—and it’s even earning extra credit with an all-over deep purple hue and trendy side-swept bangs. Bravo.
