Think You Know Reese Witherspoon's Natural Hair Color? You're Probably Wrong

While you probably know and love Reese Witherspoon as a blonde (she is Elle Woods, after all), that's not her natural hair color. The actress and activist recently posted a childhood photo to Instagram, complete with candy necklace, revealing that her natural hair color is actually brown.

Over the years the 43-year-old actress has tried a multitude of different hair colors, from deep chestnut brown to near-platinum blond, and even a red hue. Considering how flattering each hair color looks on Witherspoon, it would be hard to distinguish which is her natural hue had it not been for the childhood photo.

Ahead, you'll find photos of Witherspoon's natural hair color as well as the other hair colors she's tried over the years.
