Hair's the Scoop

Lily Allen debuted a shorter style this week in London, and I'm not sure it really does much for her overall look.

It's a little shabby-chic for my taste, but not in that slept-in, Kate Moss way... in more of an "I cut my own hair without a mirror" kind of way.

Cameron Diaz has had quite the Hairvolution- Starting with that fun, super short bob (which put her on the map), then a brief stint as a brunette, to finally find herself in a classic, side-parted shagg that's become as signature as her all-consuming smile.

More recently, Cameron's been seen sporting a major fall trend- sleek, straight hair. I personally love this new look, but find it ages her just a bit. I think the blonde, wavy style she's had for the past few years is my favorite of all (boring, but true!)...

Which of Cameron's looks do you love most?

Carine Roitfeld (aka the Editor-in-Chief of French Vogue) rocked this 'haute hippie' hat at a recent fashion show in Milian.

Yes, her body looks as though it's never seen the bottom of a tub of Ben & Jerry's. And her makeup is classic and as natural looking as covers come. I can even (well, almost) get past the cardigan/bikini combination. But that hair?!

Faith Hill is an undeniably gorgeous woman, but this stiff, voluminous puff on her head looks overly styled (and overly processed). It's not exactly the cover look I'd imagine for a country/crossover star ...

It's such a shame, really, because she looks like she's in her prime from the scalp down ... But that coif is all I can see.

I grew up idolizing Julia Salinger (a.k.a. Neve Campbell), and envied her ability to carry off a cropped cut and still look absolutely feminine. Her shiny, frizz-free locks were perfect for the time and framed her fame beautifully.

Fast forward 14 years, a few forgettable films, and the former hair muse is now popping up all over the radar ... with a look that doesn't quite scream "comeback." Where does one start? The frizz, the poodle curls, the cut, the lack of shine? It's all shockingly bad, and so sad because she has such wonderfully thick hair (and a charming face) to work with.

My Rx would be to reduce the volume, opt for tousled curls (a la SJP) or straight hair, and boost/gloss her color with a glaze.

Both Mel B. (of Spice Girl fame) and Rihanna took a risk recently with new 'dos, but only one managed to walk the fine line between fabulous and fugly.

While Rihanna took a basic cropped cut and added texture and volume, Mel B. looked as though she'd stepped off the set of a sci-fi film with a faux-hawk updo. On the bright side, her stylist was able to distract us from that outfit, which was quite the challenge in itself...

What do you think, are either of these looks a hit (or are both a miss!)?

Fall '08 has runway models and red carpet regulars alike shining in super straight tresses. And from Posh's pixie cut to Lindsay's waist-long locks, stars are proving that any length and texture can look great in this sleek style.

To get this look, be sure to use a straightening balm (like Bumble & bumble Straight), proper thermal protectant (ghd's is amazing), and a lightweight shine serum (Shu Uemura makes a great one...) for best results. And though a good flat iron can be costly, the investment is well worth your hair health. Trust me, after a season of styling, you'll see the difference!

Will you be rocking board-straight tresses this season?
