Ideal for: any hair texture and thickness

The lob is still here this fall, but some tastemakers have begun growing out their lobs, thereby setting a new trend: "in-between" hair, neither long nor short, softened by layers and light texture.

"The lob is still popular, but I think it's a bit longer, and a little more refined and polished," says Vigi. With this cut, she explains, "you can still have the sexiness of longer hair, and still be modern."

Potempa recommends reshaping your lob with "piece-y layers" and simply letting it grow -- ideally, a few inches past shoulder length. Shampoo your hair at night and sleep on it for Aimee Song's bedhead effect, or add texture with the Beachwaver S1 styling iron.

Ideal for: straight or wavy hair of any thickness

Minimalists, rejoice: Clean cuts are about to be cool again. Although layered styles are still hot, tastemakers will "bring the one-length cut back," Chaplin predicts. A center part and smooth texture make this cut particularly sophisticated for fall.

And while short haircuts aren't going anywhere, long hair is also back in vogue; just ask the ever-stylish Olivia Palermo. "I personally think it will be more about length this year," says Sturdivant-Drew. "Long hair is back, sexy and fun!"
