Multi-Tonal Wavy Brown Bob
Balayage hair color options within brown palette are endless. You can go into reddish (caramel and auburn) tones of brown or try golden shades varying from browns to blondes. In case you would like a more neutral solution, it looks like this: dark brown for the under layer, medium browns washed to the lightest ash hues towards the ends and very light thin ribbons of brown blonde throughout the length here and there.
