How Many Grafts Do I Need for a Hair Transplant?

A graft is a small unit of scalp tissue containing one or more hairs. Two people with the same area of thinning can need different graft plans. A reliable estimate needs an examination of the donor area as well as the area you want covered.

Why does the number vary?

Fine straight hair and thick curly hair provide different visual coverage. Contrast between hair and scalp, the density of existing hair and the direction in which it grows all change the result a given number of grafts can produce. A hairline also needs a different arrangement from a crown, where hair radiates from a whorl.

How should the surgeon allocate the grafts?

Ask to see your proposed hairline and crown marked separately. If donor supply is limited, discuss which zone matters most to you. Lowering a hairline increases the area to be covered and uses grafts that might otherwise be available if thinning continues behind it.

How do you compare two estimates?

Check that both clinics have counted grafts rather than individual hairs, covered the same zones and allowed for future hair loss. Ask whether the figure is an estimate or a limit and what happens if the surgeon can safely harvest fewer grafts on the day. An itemised plan should make the trade-off between density and coverage clear.
