If spring is the season of new life and resurrection, then fall is the season of reinvention. Remember when all it took was a bang trim, a new backpack and a killer back-to-school outfit to feel like a completely new woman? (Never mind that you were 11.)

There is still something totally alluring about the idea of fall makeover — and, this season, there's plenty of fresh inspiration for making over your hair. We asked seven top hairstylists about the coolest new haircuts right now. Here's what they said.

Ideal for: any hair texture and thickness

The shag is the most buzzed-about haircut this year, and it's come a long way since Florence Henderson in her heyday. Supermodel Freda Beha Erichsen is a poster girl for the edgy, rock-star shag; celebs like Julianne Hough and Lauren Conrad recently began sporting soft shags with lots of thinned-out, face-framing layers.

"All the young celebs are wearing it, especially the models," says Takisha Sturdivant-Drew, stylist to Kerry Washington and creator of TSD Hair.

"The shag is definitely here, with or without bangs," agrees Nexxus Celebrity Stylist Lona Vigi. "The key is to work with your own texture and face shape to get the right cut. It works for everyone."

The best part: This shag is practically effortless. Nicole Leal, master stylist at Nine Zero One Salon in West Hollywood, says the shag gives "lots of movement" while requiring minimal styling time.

Ideal for: straight or wavy hair, fine to medium thickness

A "'20s bob" with "natural texture and short fringe" is one of Pureology Artist Ambassador Ruth Roche's top picks for the coolest haircuts of the moment. With its blunt edge and cheek-grazing length, this look originated with Depression-era fashionistas, but the modern version has a grungy edge.

Rather than clean, sleek and graphic, the 2016 interpretation of the flapper bob is textured and piece-y -- a perfect look for women who can't be bothered to shampoo daily. "There is a strong trend of embracing natural texture," says Christyn Nawrot, national educator for Phyto.

To get this look, wavy-haired ladies should be hands-off with their hair; simply wash and air dry. If you have naturally straight hair, get texture by scrunching damp hair with mousse.

Ideal for: straight or slightly wavy hair, fine to medium thickness

Celebs like Lucy Hale and Kristen Stewart have chopped their lobs into bobs, indicating a trend toward short cuts for fall. "It's traditional and will never go out of style," says Sturdivant-Drew of the bob.

Celebrity stylist Sarah Potempa, creator of the Beachwaver Co. line of hair tools, points to the choppy bob modeled by Lea Seydoux as a favorite look for the season. Just barely "longer than chin length" with a "clean middle part" and "blunt ends," this look is equally chic when worn sleek or wavy.

To get Seydoux's tousled look, curl random sections of hair away from the face, then use your fingers to comb out the curls and slightly muss the hair at your crown. Finish with texturizing spray or powder.

Ideal for: any hair texture and thickness

Until recently, "pyramid head" and "triangle hair" were considered major hair faux pas. But lately, this geometric hairstyle is becoming a coveted look.

"I predict a triangular look will be the next must-have style," says stylist/colorist Janelle Chaplin, global creative director for O&M hair products. Sturdivant-Drew also believes that one-length, curly cuts are trending. "With this texture and style, it's a bold statement and look."

For this look, ask your stylist for a blunt cut; any natural texture in the hair will create more volume at the ends, which will achieve a triangular shape. If you have fine hair, create some body and texture by tying it in loose braids while you sleep.
