Will you always need more than one HT?

I'm going in for a procedure with Dr Bisanga in February. Just to do some temple work and lower my hairline just slightly. Estimated number of grafts 2,200 maximum.

I'm a NW 2.5 heading towards a 3. So what should I expect in terms of density and end result assuming everything goes to plan? Given in the scheme of things my MPB is still in the early stages...

Is it just a rule of thumb that you won't get the desired result in one surgery and you'll need to go back for more eventually?
