Oh, Debra Messing, what are you doing? For the most part, she's one hot mama at the unveiling of Saks' new shoe department: Her outfit is fantastic, her makeup is gorgeous... and then there's the issue of her hair. I never thought her red hair was completely natural, but these roots distract from everything else that's going right.

If you're ever in between color appointments, you can avoid this sort of root display fairly easily. Bumble and Bumble makes a aerosol hair powder ($39) that can be sprayed on roots. It's a fine, tinted powder that covers roots while adding volume and soaking up oil. While it's not cheap, it's less expensive than a color treatment—and a worthwhile investment if you know you're going to be photographed!
