Balayage doesn’t cover gray hairs, but it can help to blend them into the hairstyle. When it becomes impossible to blend the gray hairs, you’ll have to make a root tint previous to balayage, and visit salon every 4-6 weeks for a root retouch to cover the grays. Balayage can be paired with babylights that mimic the natural gray to blend it out, and hand-painted balayage through the ends. ^{therighthairstyles.com 1 2}
