1000 grafts will probably be a drop in the bucket. You cannot waste grafts on the hairline! You can sure waste them in the crown but not the hairline, within reason! This is the thing though, you may think you only need 1000, Dr Rahal may think you need 2500 in the hairline. Of course he will take your age, future loss, current level of miniturazation all into account. Do you mind posting pics?
This site is great, but you will get much better responses from much more credible posters than me with pics....ie Spex, Jotronic, Mattj, Mattz to name a few
