We're used to seeing dark roots on all the chemically assisted blondes in Hollywood, but lately things are going the other way — women with naturally light hair are going dark and showing off their much lighter roots as their hair grows out. Kristen Stewart, Lindsay Lohan, and Agyness Deyn are all sporting the look. It's an interesting reversal that's sure to garner mixed reactions. What do you think? Do you like it when naturally light-haired people go dark, and are visible roots cool?
