On the other hand, some have stood the test of time and, with a few slight modernizations, still appear on red carpets and sidewalks alike. Which ones are hairdos and which ones are hair don’ts? You be the judge:

1. Bo Derek and her beaded cornrows from 1979’s 10

2. Farrah Fawcett’s long, feathered locks

3. Cher’s long, straight, center-parted hippie hair

4. Dorothy Hammill, who brought The Wedge to the masses

5. Jennifer Aniston, whose character on Friends was the envy of women everywhere

6. Meg Ryan and her cropped, tousled curls found their way into salons in the ’90s

7. Madonna’s teased and crimped-beyond-recognition mane circa “Like a Prayer.”

8. George Clooney’s straight forehead fringe, nicknamed The Caesar

9. Christina Aguilera’s Xtina phase that brought about stick-straight black hair with a blonde top layer

The stylists behind these celebrities’ do’s marked their place in history and pop culture forever by going out on a limb and trying something new. Imagine how it would feel to see one of your styles on TV or even in the aisle next to you at the store. What will be the next big look? One can only imagine.
