I'm happy with my hairline just wanted a little bit more coverage in the back.
Something this size could need 2000 graphs. But the best thing is to get a consult in person to make sure.
You should consult with a Surgeon for tailor made medical evaluation for your case . The pictures you provide are good but do not allow for a good estimate of grafts needed. You have to share your donor side as well . In my practice for this kind of balding I would prefer to combine FUT and FUE in order to cover larger portions of balding area in a single session All the best
