Charlize Theron Beauty Evolution: From Fresh-Faced Starlet To Glamorous Leading Lady (PHOTOS)

Charlize Theron may be one of Hollywood's hottest actresses, but we find her utterly sexy for tossing the bronzer, mascara and hairspray for unglamorous roles in "Monster" and "North Country." But don't get us wrong: While we admire the South African-born beauty for her many big screen hair and makeup transformations, they've played out into many unforgettable beauty moments when the cameras aren't rolling.

From Grace Kelly curls and peachy cheeks to midnight black locks and glowing skin, Charlize is quite the chameleon. Now sporting a shaved head for her upcoming film "Mad Max: Fury Road," the new mom of an adopted son Jackson is a true example of the saying, "It's just hair."

In celebration of Theron's 37th birthday on Tuesday (August 7th), we're taking a look back at the actress' makeup and hairstyles over the years. Vote on all her looks in the slideshow below.
