Though she plays Charlotte Grayson, the half sister to the blonde Emily Thorne on Revenge, actress Christa Allen is a natural brunette. So when her role as a Janet, a zombie-fighting cheerleader, in Detention of the Dead required her to go blonde, she opted for a wig.

“My hair is too fine to bleach. I get so much breakage it's not worth it to dye it," she told Lucky Magazine. "The wig was so itchy that scratching for a month straight made my hair fall out in one spot!"

In her promo shot for the film (which went straight to Video on Demand on June 18), Christa looks like a new-generation Buffy the Vampire Slayer.

Hopefully this kickass role will prepare Christa to bring a new strength to Charlotte as she prepares to enter into single motherhood in Revenge Season 3.

What do you think of her blonde locks? Should Christa make the look more permanent? Tell us below!
