Celebrity Hairdos and Don'ts

By Paige Ferrari

It's time once again for Wonderwall's examination of celebrity hair — where it can go right, and where it can go terribly, terribly wrong.

When you're a noted sex-symbol like Kim Kardashian, there are certain rules to making a drastic hair change. One such rule is: DO make sure that short new 'do is a wig.

Jessica Simpson's locks look a bit ruffled as she exits her vehicle. DON'T underestimate the power of mother nature, Jessica. She eats extensions like yours for breakfast.

When on Japanese TV, DO make like Lady GaGa and convince everyone that Americans are loonies with Homer Simpson donuts stapled to their craniums.

Kathy Griffin relishes her spot on the D-List, and we DO love that she's kept the trademark red hair which has made her marginally famous.

Dear Hayden Panettiere, you really DON'T need to start sporting the minivan mom flip just yet. Seriously, you're only 19 years old.

We DO think Bar Refaeli and her bombshell locks will be just fine without Leonardo DiCaprio.

Oh Adam Lambert, is there anything your pointy, greasy fauxhawk can't DO?

We get that growing out one's bangs is a tough decision for a man, but groom carefully, Pete Wentz. We DON'T want to see that sideswept hair fall down into Kate Gosselin territory.

Kristin Cavallari's tousled California girl hair is DO, even if her shredded, Las Vegas cocktail waitress dress is a DON'T.

Beyonce breezed through London's Heathrow airport sporting a curly DO. Who has time for flat-irons when you're globe-trotting?

Ok, AnnaLynne McCord, we get it. You like doing the whole red-lipstick-pinup girl thing. We got it. You DON'T need to remind us further.

One of the perks of being Cindy Crawford? You DO get your own wind machine to follow your red carpet arrivals.
