January Jones Reveals Downside of Going from Brunette to Blonde: ‘My Hair is Falling Out in Clumps’

January Jones may have more fun as a blonde… but she also has a little less hair as a result.

Last week, the “Mad Men” actress went back to blonde, her third hair color in just a matter of months! In November, Jones debuted a brunette ‘do -- and before that in June, she went fiery red (with super long extensions) for her new movie “Sweetwater” – and now, her poor scalp is paying the high price of beauty.

“I have been every color and now my hair is falling out in clumps,” the 35-year-old told British magazine Grazia Daily while promoting “Sweetwater” at the Sundance Film Festival in Utah. “I’m going to have to shave it off and wear a wig!"

Although she looks beautiful in every shade, Jones doesn't have a preference on her favorite hue. "I like it all colors, it makes you feel different according to what color it is, but I prefer to be blonde. My son recognizes me in photos when I am blonde. He says, ‘Mama' ... I didn’t get treated differently when I was red-headed, but when I went dark for a few months, I was suddenly invisible. Not just as a celebrity, but to my friends and family. I was like, 'Come on you guys, it’s me!'"
