When you see the colorist at the chair next to you meticulously painting every strand of hair with bleach, that is balayage. In French, the word means sweeping or scanning. It's just a myth that balayage always looks more natural than a foil highlight. "If [the colorist] is being heavy handed, someone can end up with these chunks right on their hairline," Kari explained. "You shouldn't be able to tell the difference between a good balayage and a good foil in my opinion."
