New Blonde Allison Williams Says People Who Dye Their Hair Are Heroes: 'This Is Exhausting'

Allison Williams has spent nearly two months as a blonde - and it has given her a whole new appreciation for people who dye their hair.

“I am exhausted,” she confessed during a Tuesday night appearance on The Late Late Show with James Corden. “For all of you who have dyed hair, you are heroes. This is exhausting - who knew? There’s so much maintenance! It’s a whole thing.”

With her new golden locks, the 28-year-old actress left her Girls character Marnie behind. Just don’t ask her if blondes have more fun.

“People keep asking me that and I finally realized that they’re asking it because they’re hoping I’m more fun now,” Williams, wearing a Sally LaPointe dress, joked. “That’s definitely why. Even my friends and family are like, Are you having more fun? Is this going to be a more enjoyable relationship for us? Are you also more fun?’ And the answer is no.”

While Williams may not be having more fun, she has no regrets - especially because it’s taught her some very interesting things about men.

“It was worth it, if only to go undercover into the male psyche,” she told Corden and guest Darren Criss. “Because let me just tell you, you are real simple. Even simpler than I thought.”

The Get Out star, who is married to husband Ricky Van Veen, went on to explain the differences she’s experienced as a blonde and a brunette.

“I walk into a room and before people are disappointed by the marriage and the fact that [my hair] isn’t attached to Sienna Miller or something,” she said. “They’re like Oh a blonde person with boobs!’ And not even barely!”

“It’s so instant,” Williams continued. “And boys are just aware of a blonde head of hair in the room. I’m positive. I’ve walked this planet as a brunette with total anonymity. And now I walk into a party and people are like, [gasps].’ ”

Girls airs Sundays (10 p.m. ET) on HBO.
