Scarlett Johansson Haircut - Short Bob With Undercut

This short, ear-length bob with a high undercut is one of Scarlett Johansson's best looks. The undercut eliminates hair that can make shorter haircuts look grown out and sloppy mere weeks after each trim. If you're looking for an undercut style that will be easier to grow out, leaving longer hair on top can help camouflage the shorter pieces as they grow through their awkward stage.
