Find the Best Hair Color for Your Skin Tone

Creating contrast between your hair and your complexion is always a good idea — whether that means going lighter or darker, explains Dorram. "If your hair color is too close to your skin tone, your features will disappear," she says. Deep, dark tones of espresso and inky black look striking next to complexions like Lupita Nyong'o's. If you have a warm undertone like Yvonne Orji's, opt for maple brown, mahogany, toffee, and other rich, warm colors to bring out the apricot tones in your skin.

Darker strands look best when they reflect light, says Los Angeles hairstylist Kim Kimble. Stick with products that are free of sulfates, detergents can strip hair of its natural oil. Kimble recommends a treatment like L'Oreal Paris's EverCreme Sulfate Free Nourishing Butter. 

This skin tone can stand up to the intensity of a deep, rich brown, or another earthy color. "Add some strategically placed highlights in a subtle gold or honey if you want to create depth," suggests Robinson. To balance greenish tints in complexions with cool undertones like Alexa Chung's, try toasty shades like chestnut brown, auburn, and cinnamon. Deep brown, mocha, and violet-based colors will enhance the natural warm undertones of complexions like Shay Mitchell's. Tawny blonde, golden caramel, or copper pick up the buttery tones all work for this undertone as well. 

Any amount of styling damage can make brown hair look dry, brassy, and drab, so seal in plenty of moisture with a weekly color-preserving, strand-repairing mask like Bumble and bumble's While You Sleep Overnight Damage Repair Masque. It nourishes and mends damage from coloring and heat-styling. 

"The lighter your skin tone, the paler you can go with your hair," says celebrity colorist Rita Hazan, who works with stars like Beyoncé and Jessica Simpson. Fair complexions with warm undertones like Elizabeth Olsen's look best against hues of butterscotch, strawberry blonde, and honey. These shades play up the peachiness of your skin and cast a soft glow on your face. If you have a cool undertone like Julianne Hough, look for blue-based colors like platinum, flaxen, and champagne blonde to flatter your ivory complexion.

Most blonde tones start to fade two weeks after they've been applied, according to celebrity colorist Marie Robinson, who works with Scarlett Johansson. To keep your hue as vibrant as possible, use a shampoo that's formulated with purple pigment like Sachajuan's Silver Shampoo to counteract any brassy tones.
