How Many Grafts Do I Need for a Full Head?
Last reviewed on 21 October 2026. We review our treatment guides every six months to keep them accurate.
A full head hair transplant usually needs between 4,000 and 7,000 grafts, always planned as two procedures at least six months apart. Advanced hair loss that still leaves a band of hair across the middle of the scalp (Norwood 5) usually needs 4,000 to 5,000 grafts, restoring the whole top of the scalp (Norwood 6) 5,000 to 6,000, and the most advanced loss (Norwood 7) 6,000 to 7,000 where the donor area allows. Your own number depends on the size of the area, your donor supply and your hair type, and it is confirmed by the surgeon at your consultation.
Estimate your graft numbers in 3D
Our Interactive 3D hair transplant graft calculator lets you move a front hairline slider and a crown slider until a 3D head matches your own hair, then shows an estimated number of grafts and the price. The estimate moves in steps of 500 grafts, and the surgeon confirms the real figure when they assess your scalp.
Estimated grafts for a full head, by stage
-
Norwood 5 (front and crown loss, with a band of hair still between them): 4,000 to 5,000 grafts
-
Norwood 6 (the whole top of the scalp): 5,000 to 6,000 grafts
-
Norwood 7 (only a horseshoe of hair at the back and sides): 6,000 to 7,000 grafts where the donor area allows
Key Facts:
-
Always two procedures. Up to 3,500 grafts can be placed in one procedure, so a full head of 4,000 or more is split across two, at least six months apart.
-
Your donor area sets the limit. A typical donor area can give about 6,000 to 7,000 grafts across a lifetime, which is close to what a full head needs, so there is little to spare.
-
The front comes first. The first procedure restores the hairline and front of the scalp; the crown follows in the second.
-
Grafts are not hairs. Each graft holds one to four hairs, averaging about 2.2, so 5,000 grafts is roughly 11,000 hairs.
-
Not every full head can be restored. With the most advanced loss, the donor area often cannot cover everything, so the front is given priority.
How many grafts for each stage of advanced hair loss
These are typical ranges. Two people at the same stage can need different numbers, because heads differ in size and donor areas differ in how much they can give.
Norwood stage | What it looks like | Grafts usually needed |
|---|---|---|
Norwood 5 | Front and crown loss, with a narrowing band of hair between them | 4,000 to 5,000, over two procedures |
Norwood 6 | The band has gone, leaving the whole top of the scalp bald | 5,000 to 6,000, over two procedures |
Norwood 7 | Only a horseshoe of hair at the back and sides | 6,000 to 7,000 where the donor area allows, over two procedures |
Prices for each total are on our 4,000 grafts, 5,000 grafts and 6,000 grafts pages.
How a full head is split over two procedures
A full head is restored in two stages, because up to 3,500 grafts can be placed in one procedure and the donor area needs time to recover in between.
Procedure | Area restored | Grafts |
|---|---|---|
First procedure | The hairline and the front of the scalp | 3,000 to 3,500 |
Second procedure, at least six months later | The crown, and extra density where it is needed | 1,000 to 3,500 |
Both procedures | The whole top of the scalp | 4,000 to 7,000 |
Treating the front first means the result frames your face from the first procedure, and the second is planned around how the first has grown and how much donor hair is left. Our hairline grafts guide and crown grafts guide cover each area in detail.

Is 3,000, 5,000 or 7,000 grafts enough, or too much?
Is 3,000 grafts a lot for a hair transplant?
Not for a full head. 3,000 grafts restores the hairline and the front of the scalp, about half of what a full head needs. On its own it is a common size for one procedure, within the 3,500 that can be placed at once.
Is 5,000 grafts too much?
Not over two procedures, if your donor area can supply it. 5,000 grafts restores the whole top of the scalp for many people and sits within the 6,000 to 7,000 a typical donor area can give across a lifetime. In one procedure it would be too much; up to 3,500 are placed at a time.
Is 7,000 grafts too much?
For most people, 7,000 is about the most their donor area can give across a lifetime, so it is only planned where the donor area is dense enough to supply it without looking thin. It is always split over two procedures, and with the most advanced loss a smaller total focused on the front often gives a better result.
Is 4,000 grafts overharvesting?
No, if it is planned over two procedures and your donor area can support it. Overharvesting means the back and sides look visibly thin, and the point where that happens depends on your donor density, not on a fixed number. The surgeon checks your donor density before agreeing any total.
Your donor area decides how much can be restored
Every graft comes from the permanent band of hair at the back and sides of the head, and once it is used it is gone. A typical donor area can give about 6,000 to 7,000 grafts across a lifetime without looking thin, and a full head needs close to all of that. With the most advanced loss, the area to cover can be larger than the donor area can supply, so the surgeon plans the front at full density first and fills behind it with what is left. Our guide to the donor area explains how it is assessed.
Hair loss also keeps going after a transplant, so a full-head plan for a younger person keeps some donor hair in reserve rather than using it all at once. The surgeon will tell you honestly at consultation how much of your head can be restored and what it will look like.
Afro-textured and very curly hair
Very curly and Afro-textured hair covers more scalp per graft, so a full head can often look full with fewer grafts. The hair curves beneath the skin and takes longer to extract, so the most that can be placed in one procedure is usually about 2,000 to 2,500, and a full head may need more than two procedures. Our Afro hair transplant page explains more.
What a full head transplant costs
Prices for two procedures run from £7,398 for 4,000 grafts to £9,798 for 7,000, fixed before surgery, and each total links to its own page above. The full list is on our hair transplant cost page.

Frequently asked questions
Q: How many grafts do I need for a full head?
A: Usually between 4,000 and 7,000, over two procedures. About 4,000 to 5,000 for Norwood 5, 5,000 to 6,000 to restore the whole top of the scalp at Norwood 6, and 6,000 to 7,000 for Norwood 7 where the donor area allows. The exact number is confirmed at consultation.
Q: How many grafts are in a full head of hair?
A: A natural scalp has more than 100,000 hairs, roughly 40,000 to 50,000 grafts. A transplant does not need to replace all of them, because the eye reads a scalp as full at well below its natural density, which is why 4,000 to 7,000 grafts can restore a full head.
Q: How many hairs is 5,000 grafts?
A: Roughly 11,000. Each graft holds one to four hairs, averaging about 2.2, so 4,000 grafts is about 8,800 hairs and 7,000 grafts about 15,400.
Q: Can a full head be done in one session?
A: No. Up to 3,500 grafts can be placed in one procedure, so a full head is planned as two procedures at least six months apart, with the front first and the crown second.
Q: How long is there between the two procedures?
A: At least six months. That gives the donor area time to recover and lets the second procedure be planned around how the first has grown.
Q: Can a Norwood 7 be fully restored?
A: Often not completely. A typical donor area can give about 6,000 to 7,000 grafts across a lifetime, which may not cover the whole top at full density, so the front is restored first and the rest is covered as far as the donor area allows.
Q: How accurate is a graft calculator for a full head?
A: It gives a reasonable starting figure. Our 3D calculator's hairline and crown sliders go up to 3,500 each, so together they reach 7,000. It cannot measure your scalp or donor area and is not set up for very curly or Afro-textured hair, so the surgeon confirms the figure at consultation.
