Getty Images When Cate Blanchett takes on a role, she takes on that character's hair as well. "I don't like wearing wigs. Unless it's for theatrical effect, I prefer to use my own hair," says the Australian actress. And we're not talking about a dye job here or there: This woman has shaved her hairline, buzzed her head completely bald, and--most recently--let her roots grow in for months. We talked to Blanchett, who is the face of SK-II, about what it's like to be inside a character's head (literally).
Blue Jasmine (at a 2013 premiere for the film, above): "I let my hair grow out a little because [my character] Jasmine is down on her druthers and fraying at the seams. I thought it would be better for her to have regrowth and look a bit more like she's coming apart."

Heaven (2002): "I shaved my entire head and was completely bald. Bruce Willis was being honored for something that night--it was around the time they made G.I. Jane. I didn't want people to think I was spoofing on Demi, so right before I ran out my hairstylist gave me a wig. I look like Elizabeth Taylor in her later years."
