Megan Fox Goes Blonde For 'Teenage Mutant Ninja Turtles 2', Plus 15 Other Stars Who Rocked A Different 'Do Job For Work

The average lawyer, investment banker, or chef isn't asked to dye their hair for work; in fact, it may be even be illegal for a superior to ask their employee to make such an aesthetic change. However, actress Megan Fox has blonde hair for Teenage Mutant Ninja Turtles 2 — and she's not alone. Though Fox's new 'do is likely a wig, its not uncommon for actors to dye their strands whenever they get a new gig. In addition to gaining and losing pounds for film roles, Hollywood's finest are also required to transform their locks to fit the appearance of their characters, hence Bradley Cooper's curled 'do in American Hustle and Lea Seydoux's indigo dye job for Blue is the Warmest Color.

In fact, the simple change of a hair color can transform an actor's entire mien, from posture to preferred ensembles. Case in point, critics often attribute Marilyn Monroe's rise to prestige to the moment the former brunette chose to give her strands the platinum treatment. Mere hours after premiering her bleached 'do, the media is already clamoring to dub Fox the next Marilyn — or at the very least, an incredibly convincing blonde. In celebration of Fox's new hue, whether permanent or adopted solely for the next several months of filming, here are 15 other actresses who dyed their hair for film and television roles.
