I just pluck mine, let me know how this goes. Tweezers aren't painful a bit and it is really easy. You just hold the tweezers next to your nose at the corner of your eye and that is where your brow should start... You hold it at an angle from the corner of your eye, to a little under your temple and that is where it should end.
Then you just shape them and give them your own unique arch, thickness etc.
My sister gets hers waxed, not sure her procedure is though lol
