Undercut

Ke$ha has seriously been stepping up her glam game lately, but she still manages to keep one foot in her rocker roots. How does she do this so well? By mixing and matching her makeup. Her frosted pink lipstick is the perfect mix of girlie and punk, mainly because of its unique colour. More punk than prissy, this bright soft pink is finished off with a frosted sheen, giving it just the right amount of bad-girl vibe while still being accessible. Mac Cosmetics Sheen Sumpreme Lipglass in  Almond Blossom ($20) swooped over your lightest pink colour will deliver an on-point sheen.

The songstress keeps her tough-girl image in tact, though. By pairing such a poppy shade with her signature smoky black metallic eye, the girlish and rocker looks mesh and balance without being overpowering. Add a faux undercut style, with the help of two tight braids, and Ke$ha's party-perfect look is complete. No smeared makeup required.

We have a confession to make. Up until a few weeks ago, we didn't know that ghd stands for Good Hair Day. Yah, we know. And in case you weren't aware, today marks the inaugural National Good Hair Day — founded to encourage women to have an amazingly good hair day everyday, with the help of their trusty ghd.

We got to thinking about celebrities who always seem to be having a good hair day, and the recently local punk rock chick, Pink, sits top of mind. Miley Cyrus emulated her bleach blonde undercut, but Pink truly is the original babe with a buzz cut. Joey Scandizzo, ghd hair director and Australian Hair Dresser of the Year, tells us that getting her look at home is much easier than we think... keep reading.

Throughout her career, Rihanna has made her mark as a hair chameleon with her frequent changes in cut and colour and over the weekend, she premiered a new jet-black hue as she travelled to Japan doing press for her film Battleship. Even though the look is more serious than her previous platinum blonde with peekaboo roots, she keeps it fresh and edgy with shaved sides. It's reminiscent of her short cut from several years back that yielded many copycats but the songstress admitted on her Twitter page that she isn't quite ready for the big chop just yet.

When we spotted Louise Roe at the Costume Designers Guild Awards in Beverly Hills last night, we thought she looked different. Then it clicked. She had straight hair! No waves. No tousle. Just straight strands. And we like it! She was rocking some serious shoulders so it made sense that she kept things simple. Also switching things up was Claire Danes who went slick on top. It's a look that we've been seeing a lot of on the Fall 2011 NYFW runways — a slightly more wearable and less highly-polished version of the Herve Leger by Max Azria look. And let's not forget about Ginnifer Goodwin who busted out an undercut for the occasion. Noice. So that's Louise Roe, Claire Danes, Ginnifer Goodwin, Jennifer Aniston and Justin Bieber sporting different looks. We wonder who's going to be next. Do you like the girls' looks?

Ombré highlights may be all the rage in the hair colouring world, but as far as haircuts are concerned, if you're too cool for school the beehive, the undercut is the style of the moment. Worn by stars like Alice Dellal, Rihanna and Mel B, the look is not for the faint hearted. So if you like the cut, but don't want to shear away half your hair, you can easily fake it with these tips . . .

STEP 1: First blow-dry the hair using a light-hold gel to tame frizz. This will also give the hair shine and light staying power.

STEP 2: Next, create a deep side part.

STEP 3: On the non-heavy side of the part, apply more gel (you can even use water) to slick the hair to the side. Use bobby pins placed an inch or two behind the ear to secure. Then, spritz with hairspray to hold.

STEP 4: Brush the hair on the heavy side of the part toward the face or over the eye for emphasis. If you need more lift, simply tease at the roots or lightly spray the roots with hairspray and blast with a dryer. Or go for curls like Kelly Osbourne.
