Hair's the Scoop

Pull out your ruler and pencil sharpener, ladies — super-high buns are back.

Personally, I consider myself to be a low-bun kind of girl, but both Rachel Bilson's and Cameron Diaz's latest looks provide plenty of reasons to convert.

Do you like high buns? Would/do you wear them?

From Jessica Alba to Jennifer Lopez and Mischa Barton, it seems like everywhere you look these days there's a celebrity sporting dramatic, brow-skimming bangs.

Though it's not the easiest look to pull off, there are many ways to make it your own. The first question to ask yourself is: am I blunt (Keira) or feathered (Vanessa) kind of girl? Then it's all about the styling. Something as simple as your part can completely change the look, so don't be afraid to experiment with Photoshop or faux fringe to find your best fit.

Scared to go so short? Ask your stylist for soft layers that fall between your brow and the top of your cheekbones, then use a flat iron (like T3's Glow Styler) to add a slight curve to the hair. This way, you create the illusion of fringe without having to make a full-on commitment.

From Nicole Richie to Lauren Conrad and Katy Perry, young Hollywood can't get enough of this retro-inspired trend. And for good reason— Feathers are a fabulous way to add texture to your look, and come in a variety of colors, patterns, sizes, and price points.

Four ways to rock this trend:

Subtle Side-Clip
If the idea of a full-on feather headpiece is too much, try an elegant clip-in like Mary-Kate's. It's the perfect compliment to tousled waves, sleek side-parted styles, and romantic updos.

Boho-Inspired Headband
Embrace the season's safari and ethnic-inspired trends with a playful headband like Taryn's. Worn either traditionally or across the forehead, it's a great way to update your look for spring.

Retro Headpiece
If an old Hollywood look like Drew's excites you, try a dramatic feathered headpiece. It can instantly transform any basic updo into a glamorous evening style.

Hat-Like Headband
Maggie's oversized headband is a brilliant addition to any 'do, especially shorter styles. Paired with pin curls or a textured updo, this eye-catching accessory is sure to ruffle a few feathers.

From the runway to the red carpet, crimson-colored tresses have emerged as a key trend for spring '09. And, just like a must-have accessory or the latest hairstyle, changing color families can be a great way to refresh your look. 

To ensure our success, I've asked celebrity colorist Lindsay Rivera— of Neil George Salon in Beverly Hills— for her expert advice:

Why go red?
Someone should go red if they are looking for something playful and new and maybe if it’s something they’ve always wanted to do!

Which shade(s) of red best suits fair/medium/dark skin tones?
As far as matching skin tones— fair skinned ladies should stay on the warmer side, with strawberry blondes and more coppery tones. Medium skin can go with a beautiful cinnamon shade, or even to a deeper auburn. For those with a darker complexion, red can be tough if you want it to look natural. So those with darker skin tones are best handled on a case by case basis, but the most suitable shades are the very deep tones.

What are the best ways to ensure an A-List outcome?
To make sure you have the best transition to red, you should definitely bring a picture of what you are looking to achieve. It is important to keep your skin tone in mind. If your complexion is like Jennifer Lopez, and you pull a picture of Julianne Moore— you have some more thinking to do! In switching from blonde or brunette to red, you should be prepared to warm up and make subtle changes your makeup and wardrobe to better suit your new scarlet locks.

...So, will you be joining the likes of Lindsay and Scarlett this season?

The "Lob" (aka long bob) is the latest trend to take Hollywood, with stars of every age seen experimenting with this versatile cut.

A few favorites—

Heidi Klum: Slicked-Back
The key to Heidi's formal 'do is a sleek, lacquered finish. To get this look, try a long-lasting, strong hold hair gel— like Bumble and bumble Gellac— on wet hair.

Anne Hathaway: Romantic Waves
Loose, luminous curls work with any look, and add a softness to this (layer-less) cut. To keep your locks looking polished, finish with a lightweight shine serum like Shu Uemura Silk Oil.

Camilla Belle: Au Natural
Messy, bed-head tresses are a sexy (and easy) way to wear the "Lob." To amplify your natural texture, try Fekkai Coiff Oceanique Tousled Wave Spray.

Gwyneth Paltrow: Sleek & Straight
A classic, this smooth style can easily take you from day to night. Be sure to use a high-quality flat iron— like the T3 SinglePass Duality— when creating this look, to protect your tresses from heat and styling damage.

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?

It's rare to see a trend that's fun and functional, but this one is just that.

Starlets and socialites everywhere have been sporting skinny headbands both on the street and on the red carpet, and why not? They're the versatile, inexpensive hair-saver to stock up on this season. You can use them to help camouflage a bad bang job/that awkward regrowth period, salvage a bad-hair day, or with a brooch to add instant glamour to a basic updo. They're fantastic.

Check out JCrew.com, Goody.com, and UrbanOutfitters.com for cheap & cheerful headbands to help you get the look.
