The lob took over 2014, and with so many stars committing to the chop, one has to assume that they're probably working their way toward longer locks. So what will be 2015's style mainstay?

Get ready for "the swag," because it's already gaining traction on runways and red carpets. And it's going to be big for Spring 2016 [1], too!

Celebrity hairstylist Sunnie Brook [2], who has worked on the manes of Dianna Agron [3], Lana Del Rey, and Chrissy Teigen, spoke with Byrdie [4] about this look in November, coining the term herself. "It's a modern take on the shag haircut. Most shags look like Christmas trees — they're not very flattering. So we're swagging it up," says Brook.

I visited Sunnie at Ramirez-Tran salon [5] in Los Angeles (yes, the salon with the most Instagram-worthy hair [6]) to learn all about the new style. Turns out I was a perfect candidate for the cut, so goodbye went my long hair, and in came curtain bangs and sexy layers with movement.

Take a look at the transformation in the video above! Plus, learn who's the best candidate for the look, plus styling tips to keep your swagger in check.
