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.

After Russell chopped her locks between "Felicity's" first and second seasons, some in the entertainment industry blamed the cut for a Season 2 ratings drop."It was, like, kind of amazing that anyone cared," Russell told TODAY last October, when she reunited with "Felicity" cast members Scott Speedman and Scott Foley. "But, yeah, it was a big deal. People love hair."
