20 Haircuts That Never Go Out of Style

Jennifer Aniston has said that her hair is naturally wavy so her famous and much copied layered, shaggy "Rachel" style was shaped with flat irons and a lot of blow drying. Now, she’s known for sporting casually tousled layers which beautifully frame her face.

This textured, side-swept pixie on Michelle Williams is a timeless classic. The trick? Spritz a texturizing spray like R+Co's Trophy Shine + Texture Spray ($29; bloomingdales.com) and let hair air dry. For more polish, blow-dry gently with a flat brush.

The only thing more iconic than Naomi Campbell's runway career is her signature blunt bangs and sleek long layers. For a flyaway-free finish like the supermodel's, work a quarter-sized amount of Oribe's Imperial Blowout Transformative Styling Crème ($68; net-a-porter.com) through damp hair prior to blow-drying. 

Jennifer Lopez has perfected her look with big, cascading voluminous waves. It’s the ultimate bombshell style with a soft touch. To enhance your natural waves and volume, apply L'Oreal Paris's Advanced Hairstyle Curve It Elastic Curl Mousse ($4; walgreens.com) to damp hair before styling it. 

Cameron Diaz's sexy, choppy bob with a deep side-part is ideal for slightly wavy or straight hair. 

A layered pixie cut, like Halle Berry's iconic look, is adorable and sexy all at once, especially on a heart-shaped face. Work sculpting serum through hair and brush towards your face with a ceramic round brush like Revlon's Perfect Style Ion + Medium Ceramic Brush ($11; walgreens.com).

Here's a great example of someone who found their classic look early in life. So we hope that the Duchess of Cambridge always keeps her bouncy blowouts with face-framing layers.

Gwyneth Paltrow's ultra-smooth style parted down the middle is sleek to the max. On her Goop website, the actress credits stylist Orlando Pita’s T3 tools, like his T3 SinglePass Flat Iron ($180; sephora.com) for the look.

When it comes to her hair, Beyonce is very much the chameleon. She’s gone sleek and straight, did blunt bangs, and rocked some short styles, but her long curls will always be one of her most famous looks to date. 

These soft beachy waves give California girl Gigi Hadid an effortless vibe. To give your waves an undone finish, spritz and scrunch them with Living Proof's Instant Texture Mist ($26; sephora.com).  

Naomi Watts's long bob with a soft side bang frames her face to perfection while really showing off her eyes. This graduated look is the ideal volume booster.

Kerry Washington's long bob is instantly updated with a set of blunt bangs. Ask your stylist for fringe that falls right below the brow so that you can part them in the center, road-testing the curtain trend, if you wish.

Bella Hadid's sleek bob with blunt bangs is a chic yet bold option when you're looking for a hair change. After blow-drying with a large round brush, roll the ends slightly under, then flat iron one-inch portions. To keep the look sleek, spritz Ouai's Smooth Spray ($26; sephora.com) on damp hair. It protects against heat damage and prevents frizz. 

The quickest way to update your curly lob without a cut? Part your hair in the center. Turn to Solange for inspiration. 

It's the lob's in-between length that makes it a universally flattering cut on everyone. For an easy tousled look like Hailey Baldwin's, use a flat iron to create "S" waves, and ruffle them with your fingers for a piece-y finish. 

Reese Witherspoon's straight hair with a touch of volume is sexy yet sophisticated. For wispy bangs, work a dime-sized dab of shine serum through hair, place bangs to the side, and blow-dry the rest with a paddle brush. For thinner hair, use a balm like IGK Mistress Hydrating Hair Balm ($29; sephora.com). 

When Victoria Beckham debuted her shorter-in-back graduated bob, it was copied around the world. To add some volume, blow dry with a small brush at the roots and finish with gloss spray.

Alexa Chung's wavy shag with grown-out bangs is a cut that looks effortlessly cool no matter how you style it. 

Heavy bangs paired with a swooping side-part adds a sexy softness to Emma Stone's look. On damp hair, mix a few drops of shine serum, like L'Oreal Paris Advanced Haircare Extraordinary Oil Lustrous Oil Serum ($6; target.com), with a quarter-size drop of styling lotion. Blow dry two-inch sections with a paddle brush.

To copy Chrissy Teigen's wavy hairstyle, spritz Tresemme's Thermal Creations Heat Tamer Leave In Spray ($4; target.com) in the hair before blow-drying to prevent heat damage. Then, dry with a round brush. Curl wide sections with a curling iron with the tip of the iron facing down to the ground.
