Work out hair transplant graft count instantly with clear inputs, formula shown and shareable results.
Multiplies the recipient area by the target graft density to give the graft count, then converts to hairs and typical session numbers.
Graft count
Grafts = recipient area (cm2) x target density (grafts/cm2); hairs = grafts x hairs per graft

30 to 40 grafts/cm2 usually gives a natural appearance; native density is around 80 to 100 follicular units/cm2.
Yes. Lifetime donor capacity is finite, typically 5,000 to 8,000 grafts, so planning must reserve for future loss.
