Happy 40th birthday, Keri Russell!
A cast member on "The All-New Mickey Mouse Club" in the early '90s, Russell became a household name in 1998 as the star of the WB's "Felicity." These days, the award-winning actress continues to impress fans and critics on the FX drama "The Americans." Along the way, Russell also became a style icon, especially when it comes to her hair — including the most buzzworthy 'do of the late '90s, this side of "The Rachel."
Starting with her "Felicity" look and wrapping with her current coif, here's a look at the hair evolution of Russell.

"But, yeah, it was a big deal. People love hair."
