NW6 here, going to him in March. I'm getting pretty much the same as you. Op is on a Tues and I decided to stay until Sat to give grafts a chance lock in some before flying back to the US.
How was he about irregularities in the hairline, did he discuss that at all with you?
Any other advice, especially regarding hanging around that hotel for several days afterwards? Is room service decent / affordable?
Thanks,
Aaron
