is this a good idea?

One side of my hair has either less hair or a lot less volume than the other side, and can make my hair look sorta lopsided sometimes. Would it be a good idea to have shorter layers (to encourage more volume) cut on one side and have longer layers cut on the other? I part my hair on the side, so I don't *think* I have to worry about the layers being symmetrical, though I'm worried about looking uneven and as if I'd cut my hair on my own!
