Cosmopolitan Magazine asked recently if the ombrГ©В hairstyle trend was "over." It is not. It's a fantastic option for women with brown hair, like model Lily Aldridge here who is famous more for her ombrГ© hair than for her Victoria's Secret modeling shoots. Here, she sports deep chestnut roots that fade to a tawny medium brown.05 of 14

If your brown hair is mousey, it might be begging to go darker. Plus, it's way less harmful to go from light to dark than from dark to light. If you want to go super dark like Victoria Beckham here, you can without harming your hair too much.
So should you do it yourselfВ or consult a pro? All-over hair color is actually relatively easy to do with one caveat-if you are going more than a couple shades darker than your natural hair color, consult a pro, or risk ending up with an ugly orange tint that you'll have to get fixed.В06 of 14

Actress Salma Hayek is famous for her deep chocolate brown hair color, which almost always has copper and caramel highlights.
Colorist Kim Vo tells Harper's Bazaar that he likes for Hayek's hair to be "reverse ombrГ©. Think dark chocolate roots swept into gold tips." Again, the balayage method works best for those gorgeous sun-kissed highlights.07 of 14

What you will never find Cruz doing again, though, is dying her hair blonde. вЂњI did it once when I was 19, and I lost half of my hair,вЂќ Cruz told OK Magazine in 2009.08 of 14

The most gorgeous brunette hair shouldn't look as though it's been colored, but rather has been naturally colored by the sun.В This is what highlights do. But the best highlights don't start at the scalp, according to famed colorist Harry Josh. He told Allure magazine that he likes to weave several intensities of hair color in, so no single streak is obvious. He also employs a subtle gradation of color that's lightest at the tips. This leaves hair looking as if it was sun-kissed a few months ago, and grew out naturally.В12 of 14

According to colorist Harry Josh who does Hilary Swank's color, "Hilary is all about the less-is-more, low-maintenance school of color." This makes the gradient ombre hair color shown here, a perfect color choice for Swank.13 of 14

Gisele started the brondeВ hair trend many years ago, and it remains a favorite color choice for women wanting to stay brown but with golden blonde highlights. To get Giselle's famous color, her colorist Harry Josh leaves her natural honey brown base in place and simply adds in sunny highlights which he starts half an inch away from her roots. If you don't have Gisele's perfect base, don't worry, you can get one with all-over hair color.
