Hi Topcat,
I still see this going on which is why it is an important topic I have seen patients have surgery in the last few years with other clinics and these patients have been given totally inappropriate low hairlines on a Norwood 6 for 1500 to 2000 grafts not taking medication they have then lost all native hair and the lateral humps have dropped so there is a gap. In some cases there is just not enough donor hair to address all that they need to get them to a natural balding pattern again.
In these cases they would be best to fue out the low hairline and plant the grafts further back. Some patients are very educated and others are not in some cases I have had patients demanding these low straight hairlines with extensive loss and we will walk away.
So what do you do when you get a Norwood 7 patient in that has lost the lateral humps? You have to rebuild them or you just cannot tie the hairline to the sides or you would end up with a hairline like the line I drew in black on the patient below which is way too low. Here is an example of a NW7 patient when the lateral humps are rebuilt, he gets a natural mature look to frame his face and gets a significant cosmetic improvement.

If you were to tie the hairline to the sides without rebuilding this is what the hairline could end up looking like.
