Here at Flavorpill, we love infographics almost as much as we love Liz Lemon. So, in honor of tonight’s 30 Rock finale and Tina Fey’s 42nd birthday tomorrow, we decided to take a trip through the show’s six seasons and make a special kind of infographic — one that chronicles the tumultuous history of Liz’s locks. How do you like your Liz Lemon? With Princess Leia buns? With old-lady Joker hair? Or with her 1980s Pete Rose cut? Check out all of the above and more after the jump, and hit the comments to let us know the Liz Lemon ‘do of your preference.
