Nano combo brows are a brow tattoo style that combines machine-created hair strokes with machine shading. So there’s no manual pigment implementation, everything is done with a PMU machine. The look created are brows that look like they’re naturally full, but enhanced a bit with some makeup, like a brow powder. The strokes give an illusion of denser brow hair, while the shading darkens the spaces between the strokes and the natural brows, for further enhancement and fluffiness.
