January Jones hair brown hair houstons jeans xander

January Jones and her son Xander were snapped lunching at Houston's in Pasadena on Monday, and the Mad Men star showed off her newly dyed brunette locks!

This isn't the first time January has played around with her hair color. Back in June she went from platinum blonde to red, and while that hue was reportedly for a film role, still no word from her reps on why she went to the dark side. Maybe Betty Draper is going for a daring new look to piss off Don? Or January just wanted to switch it up for the winter? We'll keep you posted!
