Beehive? Bob? Crewcut? Mullet? Hilary Swank's next hairdo is out of her hands, as Oprah Winfrey
took the shears to the Oscar winner as part of a charity effort airing Friday on her talk show
Swank, 33, is likely to end up with a short 'do, as Winfrey reportedly cut some nine inches off her hair to donate it to Pantene Beautiful Lengths
, an initiative dedicated to supporting and encouraging women who have lost their hair during cancer treatment.
"It's taken months to get to this moment," Winfrey says. "It involves a two-time Academy Award winner, a sharp object, and me."
"I've been growing it for the last six months to donate my hair," Swank says. "I've been taking a lot of vitamins and taking really good care of it, knowing that it would go to a woman in need."
Also as part of Oprah's Great American Haircut
show, 100 viewers will get 100 makeovers over 48 hours.
