Refinery 29 noticed a rise in bi-hued hair at the spring collections, both among showgoers and on the runways. Some girls simply look like they just don’t give a crap if their roots grow out. Others are dyeing the bottom half of their hair a darker shade — reverse roots, if you will. It’s not our favorite look, but we prefer it to shaving a third to a half of one’s head. [Refinery 29]
