For selecting the right hair color always consider your skin tone and personal mood. To create the most modern look try to keep the ends of your bob sharp and flat or try soft flicked or inward curls for a feminine finish. Bob with layered cuts and shattered ends can provide just the update you need for the perfect look.

Don't think your bob always has to look the same. You could try wearing your bang (fringe) on a different side. Whether blunt, side-swept or wearing it off your face using clips, they can update your look instantly with so little effort.
