In an interview with The Independent, Maggie Gyllenhaal got a little dark about being blonde:
I dyed my hair blonde because I wanted to feel better about myself. I do like it blonde, but it doesn't make you happy. The truth is: it was a long hard winter and I thought, maybe this will change my life. But it never does. I should know that by now, I'm 36 years old.
Gyllenhaal is now brunette again. And winter's over, just as everyone promised but also refused to believe at one point. Anyway, all's well and all's good.
