So I took a tape measure to my head, and the total bald area that hairs were transplanted in was approximately 120 cm2 (this does NOT include the crown area).
Dr. Hasson said he got 4,217 grafts with a hair total of about 7,700 hairs transplanted to the front scalp and midscalp (see red box in pic).
So 7,700 hairs into 120 cm2 means each cm2 received about 64 hairs each.
All the research I've done basically says that amount of hairs are enough to create density illusion, am I right??
So if thats true then I wont need additional grafts in the red box to add more density, and I can just focus on getting the crown area next and then I'm done.
Does this sound about right, or am I making a calculation mistake here??
