THE '60s SLEEK AND SHINY

“This is good for the women that have long, Gisele–inspired layers but want something sleeker for fall," Atkin says.

 The role models: “Think Jane Birkin without the bangs,” Atkin says, who notes Rosie Huntington-Whiteley (above) as a prime example of this cut. 

What to ask for: Long with very minimal to no layers. The ends should be soft and natural, not blunt or sharp, Atkin says.

 Styling suggestions: For a smooth, shiny finish, apply oil through the ends of damp hair before blow-drying. (Try The Violet Code–approved formula Lea Journo Revive French Plum Oil For Hair & Body.) 

Bonus tip: “I suggest a straightening treatment, like a Brazilian Blowout, for the women that battle with frizz,” Atkin says. “It’s such an easy fix when you want to wake up with amazing hair every day.” 

THE SAINT LAURENT SHAG

“In spring, a lot of women got a blunt lob [long bob],” Atkin says. “Update it for fall by adding layers and a feathered bang. This cut has a cool, ‘70s bohemian feeling.”

The role models: This cut is a model favorite and the star of many noteworthy fall campaigns (Anja Rubik for Gucci and Grace Hartzel for Saint Laurent), as well as Brit It girl Alexa Chung (above).

What to ask for: A shoulder-length cut with shaggy layers around the face. And the fringe? “I call it the bitchy bang because it lands right in your eyes,” Atkin says with a laugh.

Styling suggestion: Apply Sachajuan’s Ocean Mist to wet hair, blow-dry or air-dry, and finish with a texturizing spray, like Oribe’s Dry Texturizing Spray. (Both of which have been approved by The Violet Code.)

Bonus tip: “Do not use a curling iron! You don’t want a style that looks too perfect with this cut,” Atkin says. Instead, add bends and imperfect waves with a flat iron.

THE ASYMMETRICAL BOB

Atkin describes this cut as the best way to update a bob this fall. It’s a grown-out, grungy take on the classic cut.

The role models: No shortage of inspiration here. Daria Werbowy, Beyoncé and Keira Knightley (above) have all had versions of this cut. Atkin recently gave Jessica Alba, Nicole Richie and model Chrissy Teigen asymmetrical bobs, too.

What to ask for: A classic bob that is slightly longer in the front (either on both sides or just one). “The difference of length should be about an inch, so it’s unnoticeable when you tuck your hair behind your ears,” Atkin says.

Styling suggestion: To achieve a bedhead look, use large styling clips (like Y.S. Park’s Pro Clips, which have been approved by The Violet Code) to create an imperfect wave. Pin damp or dry hair into an S wave pattern by placing clips two inches apart, each clip pulling hair in the opposite direction. Mist with beach spray and blow-dry for a few minutes to set the product. Allow the hair to cool and release the clips.

Bonus tip: Avoid ombré hair color with this cut, which makes it look too beachy. Instead, opt to go a shade richer than your current color before getting the cut.
