7. Olivia Wilde
Olivia Wilde’s brown locks suit her so much, you would be forgiven for thinking she was a natural brunette! But as it turns out, the actress dyed her hair darker to get more serious acting roles in Hollywood and avoid being typecast as the ‘dumb blonde’.
8. Sophie Turner
Think Sophie Turner is a natural redhead? Think again! Although the actress launched her career as redheaded Sansa Stark in Game of Thrones and is now playing the famous ginger superhero Jean Grey in the X-Men franchise, Sophie is in fact a natural blonde and has been seen regularly sporting her real hair color between film projects.
9. Karlie Kloss
This statuesque supermodel has been getting blonder and blonder with every passing year and is now practically platinum! Although this color definitely suits her, Karlie Kloss’s old casting shots show her true mousy-brown hair color which is less ‘bombshell’ but just as beautiful.
10. Lana Del Rey
Lana Del Rey has built the persona of a mysterious 1960s-esque songstress, complete with an auburn-colored mane to add that touch of sultriness! Although she does have naturally reddish hair, it is more on the strawberry-blonde end of the redhead spectrum – enough to make the singer unrecognizable in old photos.
