lol, yea i think it's only asians/middle eastern women that do the top too. but that's coz we have more hair! in general they think that the brow 'structure' comes from the top, so that you shouldn't touch that. i don't think they would be able to do what you want. but i'm sure you can find an asian woman who is experienced. where 'bouts to you live?
I am in the UK - North West
