Jessica Alba: "Bye Bye Brown Hair"

Prepping her hair for a dramatic change, Jessica Alba left her hair salon in West Hollywood, CA just hours before heading to a bar on Thursday (August 23).

Showing off her lighter locks, the "Sin City" beauty left the salon with wet hair, which she dried, before strutting into The Gas Lite bar, wearing eclectic blue pants and a floral blazer.

During her appointment, Jessica posted photos on Instagram and explained through a tweet that the color change is for her latest on-screen role, "Bye Bye Brown Hair", saying, "r u on viddy yet? I'm documenting my brown to Sin City blonde!"

Later in the evening, Jessica took to Twitter again to share several pictures of her "Honest" employees and interns explaining, "Hanging w my @honest team at our fav after work spot."

Check out the video Miss Alba recorded of herself just moments before her hairstylist foiled up her tresses with a lighter color.
