January Jones Dyes Hair Pink, Jokes "Call Me Frenchie"

January Jones has officially joined the Pink Ladies. On Thursday the Mad Men actress dyed her blond locks a cotton candy pink hue. She documented the transformation on Instagram by first posting a wet haired selfie mid-process with the caption: "Can you guess where I'm going with this? #backtomyroots" Then a few hours later she uploaded the "after" photo, showing off her new light pink tresses and joking "Call me Frenchie," in reference to the famous Grease character. Now this isn't the first time the 37-year-old has dyed her hair pink. Three years ago she sported rose gold highlights for a while.
