We spend lots of time focusing on what stars wear, but what about what they put on their faces? Although makeup may not seem important, plenty of women won't leave home without it.

In a survey, two-thirds of British women said that heading to the office bare-faced caused them more stress than public speaking, going on a first date or enduring a job interview. 91 percent of women surveyed would rather cancel a first date altogether than go without makeup on. And in the U.S., women spend around $7 billion on cosmetics every year.

And that doesn't even include hair. The AP recently reported that in 1950, about seven percent of women dyed their hair. Today? 95 percent or more.

With all that beauty-obsession (and our own love of makeup) in mind, we're taking a look at This Week In Beauty, showcasing the best, worst and most, um, interesting styles of hair, makeup and nails that we came across this week. Take a look, get inspired and vote for your faves!

  • Messy Bun

    There are cute messy updos... and then there's this. Unfortunately for Martha Freud, her hair makes it seem like she may have just gotten out of bed. (Getty photo)

  • Perfect Flip

    Scar Jo has been killing it lately in the hair department. While celebrating her star on the Hollywood Walk of Fame this week, Scarlett channeled old Hollywood glam her hair perfectly pulled back with a side flip. (Getty photo)

  • Drawn-On Brows

    There are a few things wrong with actress Kate Del Castillo's look at this week's screening of "Girl In Progress." First, Kate's glow is a tad too orange (we assume from too much tanning or bad bronzer). Second, her eyebrows are obviously drawn on. Penciling in eyebrows is fine... so long as we can't tell!

  • Coral Lips

    We're loving Heather Morris' coral-colored lips at this week's Academy of Television Arts & Sciences' screening of "Glee." Keeping the rest of her makeup light and simple was a smart choice! (Getty photo)

  • Awesome Nails

    We are loving everything about the nails on this model from the Carl Kapp's Australia Fashion Week show. The contrasting colors and the unique shape is eye-catching! Anyone care to give us a tutorial? (Getty photo)
