21. After dying her hair blonde to play Rosalie, a member of the Cullen family, in the first film, Nikki Reed decided to wear a wig for the rest of the series to protect her hair. “My hair fell out,” she told MTV about the damage. “Initially it took me 36 hours to get blonde and I bleached my head and skin every other day. This time we’re testing different wigs and stuff.”
22. More wig problems: After she cuts her hair to play Joan Jett In The Runaways, Stewart had to wear a wig for Eclipse, which caused quite a stir. Ahead of Breaking Dawn: Part 1, Stewart assured fans that she would rock her own hair and revealed that Summit didn't want her to cut her hair at all.
“They're going to hate me for this, but they've offered me a lot of ridiculous… a lot of ridiculous things so that I shouldn't do this,” she said George Lopez in 2010. “I completely understand that, I just thought we had a better… wig, and, uh, it's okay, we did it, and hopefully, hopefully, hopefully it's okay now.”
