Apparently, blondes really DO have more fun… at least according to Claire Foy. The Crown star, who recently went from a golden shade of strawberry blonde to dark brunette, put the age-old question to rest while appearing on The Tonight Show Starring Jimmy Fallon.

After Fallon remarked on her tress change, Foy, 33, revealed the truth about her changing hair color, saying, “I LOVED being blonde. People are just nicer — they’re just nicer to you!” she quipped. “I swear, it’s an actual thing. People hold the door open for you, they smile at you, just in general.” Hmm… that’s mighty curious if true.

Alas, Foy said she had to give it all up, mainly due to the intense upkeep. “I had to let go of the blonde,” she said. “So it had to go at a certain point.” The British beauty went back to brunette for her role as Neil Armstrong’s wife, Janet in The First Man, due out in October 18, 2018.

Blonde hair color isn’t entirely without its pitfalls, however. Disenchanted star Amy Adams said she made the swap from blonde to red to avoid being stereotyped as “flirtatious and dumb,” while Cynthia Nixon said it made her LESS recognizable than the fiery red ‘do she rocked on Sex and the City.
