1 graft ≠ 1 hair
A graft is a follicular unit — a cluster of 1 to 4 hairs that grows together. 3,000 grafts typically produces 5,000–8,000 individual hairs.

A graft is a follicular unit — a cluster of 1 to 4 hairs that grows together. 3,000 grafts typically produces 5,000–8,000 individual hairs.
You're born with a limited donor supply — usually the back and sides of the scalp (~6,000–8,000 grafts lifetime). BHT taps beard and chest as a last resort.
Going from 30 to 40 grafts/cm² is visually transformative. 40 to 55 costs 30% more grafts for a smaller visual gain. Most patients look natural at 'standard'.
Cases above ~4,000 grafts often split into two sessions 10–14 months apart. This lets the scalp heal, protects donor, and produces more uniform coverage.
