How Many Grafts Do I Need for a Norwood 4 Transplant?
A Norwood 4 transplant typically needs 3,000 to 4,000 grafts to restore the hairline, the front of the scalp and the crown, and most cases need around 3,000 to 3,500. Most of the grafts go to the front, which frames the face, with the rest for the crown. Up to 3,500 grafts fit in one procedure; where 4,000 are needed, the work is planned as two procedures at least six months apart. The surgeon confirms your number at 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 at Norwood 4
-
The hairline and front of the scalp, with an early crown: about 3,000 grafts
-
The front and a larger crown: about 3,500 grafts, the most in one procedure
-
Extensive Norwood 4: about 4,000 grafts, over two procedures
Key Facts:
-
Front and crown, with a band between. Norwood 4 has significant frontal loss and a larger crown, still separated by a band of hair. Usually 3,000 to 4,000 grafts. Most cases are around 3,000 to 3,500, with most of the grafts at the front.
-
One procedure or two. Up to 3,500 grafts fit in one procedure; 4,000 is planned as two, at least six months apart.
-
Grafts are not hairs. Each graft holds one to four hairs, averaging about 2.2, so 3,500 grafts is roughly 7,700 hairs.
-
Your donor area sets the limit. A typical donor area can give about 6,000 to 7,000 grafts across a lifetime, so Norwood 4 uses about half of it.
What Norwood 4 looks like
Norwood 4 is the fourth stage of the Norwood scale. The hairline has receded further than Norwood 3 and thinning at the crown is now clearly visible, but a band of hair still runs across the top of the head between the two areas. This is often the point at which people start to consider a transplant.

About 3,000 grafts: front and early crown
About 3,500 grafts: front and crown
About 4,000 grafts: front of the scalp and crown
How many grafts for Norwood 4 work
These are typical figures. Your own number depends on the size of the front and crown areas, the density needed, and your hair: curly or wavy hair covers more scalp per graft than fine, straight hair.
What is being done | Grafts usually needed |
|---|---|
The hairline and front of the scalp, with an early crown | About 3,000 |
The front and a larger crown | About 3,500, in one procedure |
Extensive Norwood 4: the front of the scalp and the crown | About 4,000, over two procedures |
Prices for each size of procedure are on our 3,000 grafts, 3,500 grafts and 4,000 grafts pages, and what is included is on our Norwood 4 transplant cost page.
Is 3,000 or 3,500 grafts enough at Norwood 4?
Is Norwood 4 too late for a hair transplant?
No. Norwood 4 is often when people first consider a transplant, and there is usually still enough donor hair to restore the front and the crown. Because the hair loss is active, medication to protect the remaining hair is often discussed alongside surgery.
Is 3,000 grafts enough at Norwood 4?
For many Norwood 4 patterns, yes. 3,000 grafts restores the hairline and the front of the scalp and covers an early crown. A larger crown usually takes the total to 3,500.
Is 3,500 grafts enough at Norwood 4?
For most Norwood 4 patterns, yes. 3,500 grafts is the most placed in one procedure and covers the front and a larger crown. Where more is needed, the extra is planned as a second procedure.
One procedure or two at Norwood 4?
Up to 3,500 grafts can be placed in one procedure, which covers most Norwood 4 patterns. Where about 4,000 are needed, the work is split into two procedures at least six months apart, so the donor area recovers in between. The front is usually restored first, because it frames the face, and the crown is completed in the second procedure, planned around how the first has grown. Crown loss often keeps spreading, so the surgeon may also advise treating the front now and the crown once it has settled. Our guides to how many grafts the hairline needs and how many grafts the crown needs cover each area on its own.
Some people at this stage have the Type A pattern (Norwood 4A), in which the hairline recedes from front to back as one front, without a separate crown spot. It is planned as one area across the front of the scalp rather than front and crown.
Afro-textured and very curly hair
Very curly and Afro-textured hair covers more scalp per graft, so the front and crown 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 Norwood 4 is more often planned as two procedures. Our 3D calculator is based on straight hair, so for Afro hair the surgeon assesses the number directly. Our Afro hair transplant page explains more.

Frequently asked questions
Q: How many grafts do I need for a Norwood 4 transplant?
A: Usually 3,000 to 4,000, and most often around 3,000 to 3,500. About 3,000 restores the hairline and front of the scalp with an early crown, 3,500 the front and a larger crown, and around 4,000 is planned as two procedures.
Q: Can Norwood 4 be done in one procedure?
A: Usually, yes. Up to 3,500 grafts fit in one procedure, which covers most Norwood 4 patterns. Where about 4,000 are needed, the work is split into two procedures at least six months apart, front first.
Q: Should I do the front or the crown first?
A: Usually the front, because it frames the face and is what other people see first. The crown is often completed in a second procedure or once its loss has settled, and planned around the donor hair left after the front.
Q: How many hairs is 3,500 grafts?
A: Roughly 7,700. Each graft holds one to four hairs, averaging about 2.2, so 3,000 grafts is about 6,600 hairs.
Q: Will I need more grafts later?
A: Possibly. Norwood 4 usually means active hair loss, so the hair around the transplanted areas may keep thinning, and a further procedure may be planned later. That is why donor hair is kept in reserve and medication is often discussed alongside surgery.
