22 wacky runway & red carpet 'dos

Going to Extremes

The pompadour style (named for this French madame) that Alicia Keys debuted at the Grammys was also spotted at Jenny Packham's runway show. The designer recently shot to fame when Catherine, Duchess of Cambridge, began wearing her pieces at royal appearances. (See a pic of the duchess in Packham.)

String Theory

Both Taylor Momsen and the models at Marc Jacobs embodied a ladylike messiness with stringy tendrils and smeared eyeliner. (See more pics of Momsen's Dutch model doppelgänger.)

ON GLO: More Fab Celebrity Hair

Scissors Not Required

Since her turn in The Girl With the Dragon Tattoo, Rooney Mara has made short bangs her signature style. Models at Thakoon sported the mini-fringe with choppy ends, thanks to ponytails that had been brushed and pinned forward to create faux versions of the look.

Going Big

Lana Del Rey's ultra-smooth retro beehive (also known as this aircraft) echoes the look from Anna Sui's runway show.

Pony Up

The high leather-bound ponytails seen on models at Jason Wu called to mind Lady Gaga's recent look, a platinum blond wig that pays homage to Madonna in the late '80s, as well as the kung fu fighters of video games and cult movies. (Find out which other celebs have been sporting this high and mighty ponytail style.)

Cartoon Network

Katy Perry went back to her (not-so-natural) roots with electric blue hair. Another version of the colorful crimped bob showed up on the runway at Jeremy Scott, where models donned wigs à la Rainbow Brite (remember her?).

Curl Power

From the '70s to today, legendary singer Diana Ross has been known for her wind-in-the-hair curls (check out her other iconic styles). The same untamed tresses dazzled at Badgley Mischka.

Reverse It

Ombre's reign (find out how how's it done here) may be coming to an end. Instead of dark roots with light ends, the latest look is light roots with dark ends, a style seen on Beyoncé during her late-pregnancy days.

Bobbing Along

Beatle-mania is back—sort of. Singer Ameriie lopped off her long hair (see pics here) in favor of this slightly androgynous late-'60s bob, similar to this coif seen at Issa during London Fashion Week.
