Adele

Pro tip: Go for a middle part. "Adele looked great at the Grammys with this hairstyle," said hairstylist Neil Grupp of The Wall Group talent agency. "It always slims the face and gives a feeling of length. The sides are sitting on the face slim as well."

Amy Adams

Pro tip: Try soft, loose waves angling away from the face. "Amy Adams looked great at the Golden Globes," Grupp said. "A curling iron is key for this look and a Mason Pearson brush."

Cameron Diaz

Pro tip: Your part doesn't have to be perfect. "Cameron Diaz looks beautiful. For a natural-looking part, use your fingers and not a comb," Grupp suggested. "There is some bend in the hair, which gives it some texture and softness."

Mariska Hargitay

Pro tip: Keep your look minimal. "Mariska has a lob with a slight shape that gives her a youthful vibe" said celebrity hairstylist Marc Mena, who works with Neve Campbell, Nina Garcia and Mary Louise Parker.

Charlize Theron

Pro tip: Ask for some textured pieces around the face. "Texture looks great and always softens a round face. Showing the ear breaks it up as well," said Grupp, adding: "I love this blond color."

Chrissy Teigen

Pro tip: Create volume on the top. "Another key tip is volume on top to give a sense of length around a round face," noted Grupp. 

Queen Latifah

Pro tip: Ask your stylist to razor cut into the ends for a choppier look. "If you don’t feel like you can pull off a super blunt bob, but love the length, this is your haircut. This cut can also save you from going anywhere near a 'mom bob,'" said celebrity hairstylist DJ Quintero, who works with Katie Holmes and Sarah Jessica Parker. 

Christina Ricci

Pro tip: Ask for thick, blended bangs that cover the forehead. "The sweeping angle of Christina Ricci's bangs elongate the face and balance out the face shape," said celebrity hairstylist and creator of the Beachwaver, Sarah Potempa.

Drew Barrymore

Pro tip: Ask for layers to be cut vertically. "Long layers, like these on Drew Barrymore, make larger cheeks look smaller," said Potempa. 

Emma Stone

Pro tip: Try a structured lob with a twist. "This lob is cut shorter in the back and longer in the front for a trendier look. The slight bang is swept to the side, which does a nice job of framing the face," said Potempa.

Ginnifer Goodwin

Pro tip: A pixie adds height to the face. "Before taking this big of a hair risk, try a wig or a hair app first, and ask your stylist for their opinion," Potempa suggested. 

Jennifer Lawrence

Pro tip: Ask your stylist to use texturizing shears for a piece-y look. "This is a textured bob that is off-the-shoulder. It helps create negative space, which elongates the neck and face," explained Potempa. 

Jessica Biel

Pro tip: Try a blunt cut ... but keep it long. "Jessica Biel's face shape works best for this haircut because it brings out her jawline and cheekbones," said Frederic Fekkai hairstylist Giovanna Lampo. 

Kate Bosworth

Pro tip: Go for long layers with soft ends. "The longer pieces at her center part slim her forehead, creating softness and allowing your eyes to gravitate to her jawline," said Lampo.

Nicole Richie

Pro tip: Ask your hairstylist to give you options. "This blunt lob is great. If you are a 'flipper' (a girl who flips her hair side to either side), ask to cut it down the middle," said Quintero. 

Kate Upton

Pro tip: Ask for lots of layers to create volume and movement without sacrificing length. "Her round face works with this look because the majority of volume is by her jawline," explained Lampo.

Kelly Clarkson

Pro tip: Try a side part. "With a round face shape, your hair can give the illusion of splitting your face in half," said Quintero. 

Penelope Cruz

Pro tip: For thick hair, keep hair long. "This look is great for women who have thick hair and love their volume," said Quintero. "But remember: The shorter you go the more high maintenance."

Kristen Dunst

Pro tip: Ask for a long, side-swept bang. "The side-swept bang works best for narrowing the forehead, bringing attention toward the eyes," suggested Lampo. 

Lauren Conrad

Pro tip: Ask for face-framing angles with long layers and blunt ends. "Lauren Conrad's face shape works best with her angles in the front, opening up her face and neck," explained Lampo. 

Mandy Moore

Pro tip: Keep bangs choppy at the ends. "Mandy Moore's choppy bangs give her a playful look that brings out the apples of her cheekbones," said Mena.

Michelle Williams

Pro tip: Keep fringe heavy to balance out cheeks. "Her edgy look is softened by the long fringe that frames her face," said Mena. 

Mila Kunis

Pro tip: Ask for the first layer to start below the cheekbones. "Mila Kunis' beautiful long hair is layered to soften her square jawline," explained Mena.

Mindy Kaling

Pro tip: Ask for a square shag. "This haircut works for Mindy Kaling because it gives her volume on top and frames her face in the shape of a square instead of a circle, which is more flattering," explained Mena. 

Malin Akerman

Pro tip: Go for a bob with heavy fringe. "Adding in waves keeps her look fresh and youthful," said Mena.

Olivia Munn

Pro tip: Bring in photos to see if this cut will work with your hair texture. "This minimalist look is low maintenance  and great for moms on the run," said Quintero. 

Selena Gomez

Pro tip: Get a "dry cut." "This is great for people with lots of weight in their hair. Ask your stylist to soften all of the lines that he or she cuts. this can be done many different ways one of which may be a dry cut, which you are guaranteed a softer look," said Quintero. 

Tatyana Ali

Pro tip: We'll say it again ... Long layers are your friend!  "Tatyana has great long layers around the face that make it easy for her to switch up her part. Once again, longer layers equals less maintenance," said Quintero.
