Is this THE haircut of the year?

Super straight, polished hairstyles are SO last year. Celebs left and right are now opting for a messier hairdo called "the swag." Last year, celebrity stylist Sunnie Brook coined the term as an update of the shaggy hairdo that was popular in the '60s and '70s. The modern version is still going strong this year, with more and more stars choosing to forgo the flat iron and let their strands go rogue. Of course, there's a method to the madness — their hairstylists know exactly what to do to make these messy cuts look effortless.

As Allure points out, this type of style is perfect while growing out a haircut — especially the lob trend. The shaggy layers can pretty much work with any length, whether it's an above-the-shoulder bob or longer. It can also help bring volume and texture to fine hair. Sound good? Take a look at the celebs who are choosing shaggy instead of sleek.
