Air-brushing in magazines is so ridiculous sometimes (do you really think Uma's knees are that shiny and perfect). But I'm surprised in this photo by what they didn't edit out in this shot. Hot damn, look at those ROOTS!
Chances are, if you're breathing - your hair is growing. Roots are nothing to be overly ashamed of in day to day life, but do you really want them showcased on a magazine cover? But if they're going to go through the trouble to airbrush off 10 years, you might as well airbrush off a month's worth of regrowth.
