Taylor Swift's hair has inspired many a woman -- myself included -- to make the chop. One of Tricomi's favorite ways to style a shag haircut is to blow dry it straight, then use a wax (try Warren-Tricomi Style Wax, $18) to spike it a bit. A wax or paste is essential when styling your shag, as it gives the cut hold and definition.

Ashley Benson's shaggy 'do has tons of texture. "The messier, the better," says Salcedo. He says a salt spray will give you overall texture and help you bring out waves in your hair. "Scrunch the product onto your hair, shake it up a bit and call it a day." Easy peasy.

"My No. 1 modern shag icon is Alexa Chung, hands down," says Salcedo. And he's not the only one: The "It" girl is known for her layers and fringe. Here, she wears it short and blunt her bangs pushed off to the side, but she also wears it (and looks equally amazing) longer and supermessy -- making her the perfect person to showcase the versatility of this hairstyle.

Bored with your current hairstyle? Salcedo says that clients who most often ask for the shag haircut are women who want to switch up their day-to-day routine. "It's for clients who want to spice up their look," he says. "This haircut makes a bold statement of, 'Hey, look at me. I'm confident!'"

Roszak prefers this style to look as effortless as possible. To get that #wokeuplikethis vibe down pat, she recommends using a mousse, like L'Oréal Paris Advanced Hairstyle Boost It Volume Inject Mousse, $4.99, to add more texture and volume to hair.
