Most Helpful Girl
Just explain it exactly like you told us on here. Say, "I want my hair parted from the left (showing her where to start the part), and I want it to be *this* long on the top, but slightly shorter on the sides". It sounds to me like you're wanting a less extreme version of the military style "high and tight" marine cut.
^Does that look something like what you're describing? I envisioned something like this, but with the hair longer all around, and flowing toward the left slightly. I like this style of cut, it's very handsome in my opinion.
