"Balayage is a French word for sweep," said the colorist. "Technically, it means that you area-painting highlights on the hair in a sweeping motion." Highlights will be in chunkier sections, making it seem like the sun naturally lightened the hair. Because no foils or meche is used to apply product, sections are less saturated than typical highlights and regrowth lines are less noticeable. Your hair will look just as good whether it's one week or one month from your initial salon appointment.
