As opposed to standard highlighting methods that use foil or a cap, balayage is strictly freehand where the color is painted on. You can amplify the hue to vary from a soft wash to bright and bold depending on your personal preference. Outside of very short cropped hair, it can work on a variety of hair lengths, textures and colors, making it truly universal and flattering for all women. Most are drawn towards it because the maintenance level is relatively low; many are able to go four months between color treatments.
