Hair's the Scoop

Sienna Miller's signature is a tousled, "undone" look, but this recent style (or lack thereof) has me wondering if she's lost her touch.

The "G.I. Joe" star's hair is vibrant and healthy-looking, but it's hard to focus on the positive with those random pieces floating around her face. They make her locks seem fine and stringy.

I'm all for messy updos, but also believe there's a fine line between flattering and faux pas.

Seen here on the runway of Isaac Mizrahi's Fall 2009 show, this model appears to be wearing a hat. Or is it a handbag? Perhaps a 2-in-1?

I know we're in a time of economic hardship, but really... This is a multi-use innovation I could live without. It's neither beautiful nor discreet (with the latter being key to saving/hiding a bad hair day!).

I'm out sick today so, naturally, I made a point of indulging in the one guilty pleasure that comes with staying home on a weekday — daytime TV. Just as I was flipping though the blur of court cases and love triangles, I happened to land on a Rachael Ray beauty segment featuring — you guessed it — Bumpits. The name alone made me want to drop the remote and attempt to focus through my medicated haze.

What are Bumpits exactly? According to the brand, they're "volumizing plastic hair inserts [that] take your hair from flat to fabulous in seconds without the use of heavy creams or gels. [You can] simply place the piece underneath hair at the crown of your head to instantly transform your look."

Now I'm all for a lift, but these plastic pieces seem to better fit the age of Marie Antoinette or The Ronettes than the modern day. Hair should have movement, which is why I tend to prefer extensions, fillers (made of natural/synthetic hair) and styling products to these sorts of rigid inserts. But then again, I haven't tried a Bumpit, so perhaps I'm terribly mistaken ...

Beyonce Knowles has been channeling her on-stage alter ego, "Sasha Fierce" recently, and it seems her old self is being stored in that over-the-top coiff.

From her voluminous updos to looks (like the one above) that must take multiple rounds of hairspray to achieve, this incarnation ages her greatly and pays homage to a time in hair history we've all tried so hard to forget.

I'm all for experimentation, but I also believe in soft, touchable hair that looks beautiful. And teased tresses, like Mrs. Carter's, are just the opposite.

Christina Aguilera's new look has been a topic of much debate recently (Did she knick her style from Lady Gaga? What's that 50s-meets-punk-meets-peroxide coiff she's been sporting? Why the wigs?), but her latest, Audrey Hepburn-inspired 'do proves there's still hope.

This smooth, polished updo has Christina's locks looking the healthiest they have in years, and I'm loving the length. But do these cropped bangs work, or should they be banned from Tinsletown all together?

Every trendsetter, from Nicole Richie to Carrie Underwood, has been spotted recently wearing a metallic headband across her forehead.

I consider myself to be fairly experimental, but I think I'll leave this one to the ladies of the red carpet. I just can't see myself wearing one of these haute-hippie headbands with enough confidence to do the look justice.

What do you think, are metallic headbands a trend or foe?

It seems that Paris Hilton sees the same stylist for her extensions as former frenemie, Nicole Richie. Both have been spotted recently with their plugs out for the world to see (and snap).

This trend reminds me of the whole panty-above-pants movement, where you didn't know whether are to say something or look away... Could this be done on purpose? And if so, why?

I just think that some things are best left to the imagination, and faux hair is definitely one of them.

What do you think of exposed hair extensions, are they a trend or foe?

Portia models crimped hair with a modern flair.

Is this '80s flashback a trend or foe?
