4000 Grafts Hair Transplant
Broader coverage including the crown — what 4,000 grafts do.
A 4,000 grafts hair transplant equals about 8,000–10,000 hairs, typically covering Norwood 4 to early Norwood 5.
A 4,000-graft hair transplant provides broad coverage, often including the front and early crown (Norwood 4–5).
What it covers
Front, mid-scalp and early crown with good density. See graft planning and crown transplant.
What 4,000 grafts cover – and what not
4,000 grafts equal about 8,000–10,000 hairs, typically covering Norwood 4 to early Norwood 5: hairline, front zone and part of the mid-scalp – or front plus a moderate crown, but rarely both at maximum density. It is the number where honest planning begins: what do we prioritise?
Front or crown? A decision, not a formula
With limited donor material the rule is almost always: the front zone comes first. It frames the face and is visible in every mirror and photo. A crown stays unobtrusive as long as the front holds. Trying to cover both with 4,000 grafts gives you both thin – and nothing left for touch-ups.
Is a 4,000-graft session still sensible?
Yes, in experienced hands. It runs 8–9 hours, often split over two days. Critical is the ischemia time: the longer grafts are stored outside the body, the lower the survival rate. Large sessions need a large, practised team – not a tired one.
Think in a lifetime, not a session
Donor hair does not grow back. On average 4,000–8,000 usable grafts are available over a lifetime, and only about 40–50% of donor capacity can be safely harvested. Hair loss is progressive: the transplanted hairs stay, the native ones behind them keep falling. Without medical support a gap can form behind the new hairline.

When 4,000 is the right number
When measured donor density is high enough, hair loss is medically stabilised, and the area justifies it. If any of these is missing, 4,000 is not a solution but an early withdrawal from a finite account. See 3,000 grafts and 5,000 grafts.

4000 grafts hair transplant: key points
With limited donor material the front zone comes first – covering front and crown together usually gives both thin.
The session runs 8–9 hours, often over two days; ischemia time decides survival.
