You are going to need another round. Thats the only bad news I can come up with, and thats not really all that bad. You have every reason to feel optimistic at this stage. A win-win situation is when a doctor gets publicity that there is actually someone on the planet practicing this type of surgery that does not always put profits first, and you get an overdue introduction into the wonderful world of body hair as camouflage.
Over the next 4 months you might want to determine how many grafts you and Dr. Bisanga will think are necessary to give you the density you desire without a concealer. Just my .02
Cheers.
