Kate Middleton tops our social feeds again this week with some hair dramatics. First, she fired her hairdresser (gasp!). Then, she was spotted with a new brunette dye job, and she finished out the week with a huge hair first — a red carpet ponytail. Plus, it's the holidays! So our networks were bubbling over with all things festive. Secret Santa gifts, snowflake nail art, and seasonal styles were winners across the board. See all your favorite beauty news from the week that was, and make sure to follow POPSUGAR Beauty on social media, including Pinterest, Facebook, Twitter, Instagram, and Google+.
