first step is to find the docs that are ISHRS certified.. there are a couple great ones in new york area.

I agree with the above comments.. there is a reason why good docs aren't aggressive with hairlines.. because you will look ridiculous as you get older.. and because you may waster donor hairs filling in the lower hairline and not have enough to cover other areas that will need it as you get older.... those other areas may end up looking too thing because you catered too much to your lower hairline.. one way to mitigate that would be to not have a dense lower hairline.. but if your hairline is so low, naturally you would think it should be pretty dense, right? so i just think it is not a good idea.
find the ISHRS certified docs, talk to a couple, see what they say.
