Transformation

Since she started modeling at age 10, Amanda Seyfried has maintained an enviably long blond mane. "I really don't do much to my hair," she told InStyle, admitting that its healthy state required little more than shampoo and conditioner. As her star has risen, Seyfried has experimented with retro curls and edgy updos, but has no plans to go for a major crop: "I would chop it all off for a movie, but the role would have to be worth it." Casting directors, take note!

"I kind of look the same," the Allentown, Pa. native told In Style of this picture. Indeed, at age 10, the budding model was already flaunting long blond mane.
