1. Hair Transformation: Shakira

2. Hair Transformations: Cameron Diaz
Cameron Diaz shocked the world when she suddenly went from her signature California blonde highlights to a rich all-over brunette tint in September 2006.
3. Hair Transformation: Sofia Vergara
As Sofia Vergara’s admitted many times, it wasn’t until she dyed her naturally blonde hair a warm brown hue that casting agents would believe she was Latina. This was one major hair change that clearly worked in her favor!

A little less than a year ago, Grey’s Anatomy star Sara Ramirez had fans riveted when she shortened her shiny black strands to a chic chin-length bob.

Fergie’s never been shy about transforming her look, but it was in March 2009 that the Black Eyed Pea made her most dramatic change, going from ashy blonde to dark brunette.
6. Hair Transformation: Demi Lovato
It’s been quite the eventful year for Demi Lovato, who has experimented with a handful of hair colors since exiting rehab earlier this year. The most shocking hue change: this bright auburn color she debuted on twitter a month ago.
7. Hair Transformation: Salma Hayek
Mexican actress Salma Hayek surprisingly lopped off her long layers in favor of this sleek blunt bob at the end of 2009. Since then, her hair has been inching back, but still hasn’t gotten as long as it once was.
