Advantage: The greatest advantage is that it's cheaper! Instead of 4-6 weekly trips to the hairdresser to get your roots done as with highlights, with a Balayage where you roots are left natural, they can be left for quite a lot longer, as you already have that grown out effect and have no regrowth.

Take a section. If you're dyeing your whole head, and it doesn't already contain any colourant, dye the mid-length and ends of your hair first – hair at the roots will take colour much quicker, so leaving that until last will give your final style a more even colour. ... Do not bring the colourant too close to your scalp.
