"The shag is a haircut that builds volume around the face, and is almost always best with curly hair," said Cash Lawless, a NYC-based celebrity stylist who has worked with Mandy Moore and Evan Rachel Wood. "It's popular right now as more and more women are embracing their curls."
That said, it is possible for those with fine, thin, or superstraight hair to pull off this edgy look — with the help of a perfect air-dry. A pro tip from Lawless: "Air-drying can be a volume-killer, so tease the roots around your crown up with a comb to bring life back into the hair."
Vercher added that before you air-dry, add in some texture spray to separate the strands. This ensures that your hair looks choppy, piece-y, and ready for The Deuce central casting. Once your hair is no longer wet, Lawless likes to spritz in dry shampoo at the roots as a final tszuj for extra volume.
