With professional glam squads on speed dial and thousands of dollars of high-end beauty products on-hand, it's hard to believe that Hollywood A-listers could ever have a bad hair day. No matter the red carpet appearance, stars like Kim Kardashian and Bella Hadid always seem picture-perfect -- there's not a hair out of place!
Sometimes, it's not so much about frizzy hair or split ends. Instead, what constitutes a good look extends far beyond the leave-in conditioner and into the world of color and cut. But, it's more complicated than that.

Margot Robbie in 2016
Margot Robbie this winter
"Margot’s hair gives her a modern interpretation of ‘Old Hollywood’ glamour. A much more linear line shows off her bone structure and the richer blonde brings out her beautiful blue eyes. The focus here is all cheek bones and eyes: Sleek, polished, beautiful."
Khloe Kardashian in 2015
Khloe Kardashian in 2017
"This gives Khloe a more sophisticated look. It’s strong with an edge but is still long enough to be sexy. The move away from the paler beige blond towards a more golden blonde softens the look and adds dimension complimenting her skin tone: Elegant and sophisticated."
Lucy Hale in 2011
Lucy Hale in 2018
"The change in Lucy Hale’s hair has taken her from a ‘sweet girl’ look to a sexier, edgier look. The shorter hair makes those beautiful eyes the star attraction. The dark, rich color gives the look it’s strength whilst the textured ends give it its softness: Sexy, strong with edge."
Rachel McAdams in 2012
Rachel McAdams in 2016
"Rachel’s new look accentuates her neck line and the softness around the face, her cheekbones. This length makes her hair look fuller, more robust and the color is a warmer, golden tone. The warmer blond compliments her skin tone: Strong but still fun and flirty."
Bella Hadid in 2016
Bella Hadid in 2017
"The move away from long all one length gives more interest to Bella’s look and the center part allows the shorter style to frame her features perfectly. The rich brunette color works well for her skin tone and makes her eye color really pop: Classically beautiful."
Jenna Dewan in 2007
Jenna Dewan in 2018
"This length on Jenna is a real statement length. No hiding behind hair here, it really opens up her face. Her check bones prominently come to the fore and the deep, lush, rich brunette color intensifies her amazing green eyes. Sultry and stunning."
Kim Kardashian in 2012
Kim Kardashian this summer
"Ever the hair chameleon, this look really compliments her jaw line, elongates her neck and accentuates her cheek bones. The rich color compliments her eye color perfectly because of the way it frames her face. The dichotomy of the deep, dark brown hair next to the whites of her eyes, makes the caramel in her eyes stand out: Rich, lustrous and bold."

Mad Men screen siren Christina Hendricks’ bob is one of the most flattering options around, thanks to its delicate side-swept bangs and face-framing waves. To get the look, curl front sections around a large-barrel iron, wrapping strands in the direction away from your face.
Model Karlie Kloss keeps it classic with her timelessly chic blunt bob. She modernizes the look by giving her bangs a soft sweep and creating a deep side part. For the same bounce and body, apply some light volumizing serum on roots before drying with a round brush, curling under at the ends.
Imperfect curls give actress Nikki Reed’s chin-length chop some sexy texture. Wrap two-inch sections of mid-shaft hair around a curling iron, keeping ends loose so they fall straight. Finish the look with dry shampoo and tousle ends with your fingers.
Nicole Richie has perfected the ‘lob’ hairstyle, proving that the easy-to-wear long bob style has staying power. Ask your stylist to create a very subtle angle; keeping the front strands slightly longer than the back. Smooth on some shine serum and make a defined side part to match this look.
Quite possibly the most universally flattering hairstyle out there, a bob like Naomi Watts' is a classic cut — yet somehow feels very of-the-moment. A center part and just a touch of wave lend a not-too-drastic, but still dramatic, finish. Not to mention that it's incredibly easy to style by doing nothing more than chasing a round brush with your hairdryer after towel drying.

Rose Byrne’s sexy bob gets texture from loose, beachy curls. For waves and extra volume at your crown, mist hair with dry shampoo and twist small sections into loose ringlets.

This platinum blonde bob rocked by Christina Aguilera makes a classic statement with blunt bangs. Style the look with a center part and be prepared to maintain your fringe with trims every three weeks.
This chin-length bob suits Rachael Taylor’s straight, fine hair. Blow dry hair straight with a paddle brush, then smooth some styling balm through strands with your fingers, combing one side behind your ear for a slick finish.
Nicki Minaj’s punched up bob stands out with rosy streaks. Known for her colorful wigs, you can tame the look with just a few hot pink clip-in extensions, trimmed to match the length of your bob.
A wide side part and slightly mussed texture mirror Cameron Diaz's laid-back attitude, even on the red carpet.
