Hairdos and Don'ts for Sept. 29

By Dana Flax
Oh, Jessica Alba. DON'T you know that nobody should ever dye her hair a shade of red not found in nature? And nice try, but that subversive bra strap appearance won't distract anyone from this fact.

DO add a little glam to your updo with a glitzy headband accessory, just like "Mad Men" star January Jones. Matching sparkly radiance always a plus.

Sharing something special with your boyfriend? That's OK. But DON'T let it be his fluffy platinum hair, Kelly Osbourne.

Shakira's glamorous DO proves that foreign power outlets don't stand a chance against her innate curling iron prowess.

Juliette Lewis' bird-brained headdress appears to be a misguided tribute to Native Americans. DON'T try this at home, unless you're in third grade and it's for the Thanksgiving play in school.

We're typically not in favor of anything that reminds us of Grecian Formula, but Stephen Moyer's newly-lightened locks are a surprising DO. As is Anna Paquin's expert blowout. Go on, show those "Twilight" kids who's boss where it really counts; in fabulosity. It's not like age is a basis for competition, anyway.

Modeling the stringy locks of an ocean-wading golden retriever, Kim Raver serves as a DON'T PSA to all creatures living within the "Lipstick Jungle" and beyond.

"Gossip Girl" star Hilary Duff's meticulous highlights DO impress us, particularly on an overcast autumn day. Hil knows that chilly weather is in no way a viable excuse to become root-tastic, especially when you've got a pristine reputation to protect.

DON'T leave the house looking like you've borrowed a wig from the "That '70s Show" storage closet. Especially because you're usually so put together, Paula Abdul.

Of the several notable DON'Ts in this picture, I'd like to isolate Aubrey O'Day's newfound hair extension abuse. Though Holly Madison's mind-boggling, sparkly baubled gown is a real gem, too.

Sigourney Weaver shows that bobs are a real DO when accompanied by just the right amount of flounce and "been there, done that" sass.

Naomi Watts' inevitable helmet hair is a DO, as it's important to use proper precautions when cycling, no matter the flattening consequences. Safety first, kids!
