chanelno5, go to someone who specializes in brows and does both. Doing just one sometimes isnt the best.
In previous experiences here, make sure and keep insisting what you want done. Whether its the natural look or whatever.
Also you may want to bring a reference of what you mean. If you mean natural bring a model picture with you. If you want a celebrities brow, then bring a picture of them.
Make sure you know what you want and again, insist that you get what you want. Brows are very personal so you dont want to be stuck with ones you dont like.
Another tip, look at the professionals brows. Say if you like them or say something thicker than yours or I dont want mine that thin.
Take your time and hopefully the results will satisfy you.
