How Much Does 4000 Grafts Hair Transplant Cost and Cover?
A 4000 graft hair transplant costs £7,398 at My Hair UK, planned as two sessions a minimum of six months apart. Those 4000 grafts cover about 100cm2 at the hairline, or about 160cm2 on the crown, and in practice at this number most plans treat the front and the crown together across the two sittings.

The Cost of a 4000 Graft Hair Transplant
4000 grafts costs £7,398 at My Hair UK. That is the total for both sessions, agreed before the first one, and it does not move on the day.
The price is worked out from the total number of grafts, not from how the two sessions are split. 4000 grafts costs £7,398 whether it is planned as 3500 and 500, 2000 and 2000, or anything in between. That matters because it means the split can be decided on clinical grounds alone, by what your scalp and donor area allow, rather than by what makes the quote cheaper.
That works out at £1.85 per graft. It is higher than the £1.40 per graft on a 3500 graft single session, and the reason is straightforward: two surgical days cost more to run than one. You are paying for two full theatre days, two surgical teams and two sets of aftercare, not for the grafts alone.
UK clinics widely quote £9,500 to £11,000 for 4000 grafts, and per-graft pricing is commonly quoted between £3 and £5.
The price covers both consultations, both procedures under local anaesthetic, all post-operative medication, your aftercare kit for each session, and in-person follow-up appointments throughout. There is no consultation fee, and nothing is added on the day.
The one exception is PRP, which is a separate treatment rather than part of a transplant, so it is not included and it is not standard. Some patients choose to add a session on the day or later on, and it is charged separately if they do.
If you are weighing this against going abroad, our UK vs Turkey pricing comparison sets out what the difference actually covers.
Every quote is a fixed price agreed before surgery, not an estimate. If you would like to know what your own number would be, send a few photographs and we will come back with a graft range and the price attached to it.
Why 4000 Grafts Takes Two Sessions
3500 grafts is the largest volume that can safely be placed in a single day. The limit is not the surgeon's time, it is the scalp: both the donor area being harvested and the recipient area being planted have to heal, and beyond that number the tissue is being asked to do too much at once.
4000 grafts is therefore planned as two procedures, split a minimum of six months apart so the scalp fully recovers between them. That gap is not padding. It allows the donor area to settle, the transplanted grafts from the first session to establish, and the surgeon to see the actual result before planning where the second session goes.
That last point is the real advantage of staging. The second session is planned around a result you can both see rather than a prediction, so density can be added exactly where the first session needs it.
If you have been offered 4000 grafts elsewhere in a single sitting, it is worth asking how the grafts are being counted and what density is being planned across the area.
How Your Hair Type Changes the Maximum
3500 in one day is the maximum possible, not a number everyone reaches. What your scalp can safely give in a single session depends on your hair, and the biggest single factor is hair texture.
Very curly and afro-textured hair curves beneath the skin as well as above it. The follicle does not run straight down, so each graft takes longer to extract and carries a higher risk of being damaged on the way out. Working carefully rather than quickly is what protects the grafts, and that lowers the number that can be taken in a day. For patients with very curly or afro hair the realistic single-session maximum is often closer to 2000 to 2500 grafts.
That does not change the total you can have, and it does not change the price, which is set by the total number of grafts. It changes the shape of the plan: more sessions, spaced the same minimum six months apart. Your surgeon will tell you at consultation what your own per-session maximum is, because it is assessed from your donor area rather than assumed from a table.
How Much Does 4000 Grafts Cover?
4000 grafts covers about 100cm2 at the hairline, or about 160cm2 on the crown. The difference is density: a hairline needs around 40 grafts per square centimetre to look natural because it is seen straight on, while a crown can look full at 25 because the hair lies flatter and catches less light.
At this number, though, coverage is rarely a single-area question. 4000 grafts is usually planned across the front and the crown together, because loss extensive enough to need this many has normally reached both. A typical plan puts the larger share into the hairline and mid scalp, where density matters most, and the remainder into the crown.
Your own number is worked out per square centimetre from your hair thickness, the colour contrast against your scalp and the density you want, so treat these as a guide rather than a quote. We can usually estimate to within a few hundred grafts from photographs, and confirm it at a free consultation with the surgeon who would carry out your procedure.
4000 Grafts Coverage by Area
Area | Grafts per cm² | 4000 grafts covers | What that looks like |
|---|---|---|---|
Hairline and temples | 40 | 100 cm² | The front and mid scalp at full hairline density |
Hairline and mid-scalp | 30 | 133 cm² | The whole front half restored as one area |
Crown only | 25 | 160 cm² | A very large crown, rarely treated alone at this size |
Why 3500 Is Our Maximum in One Session
3500 grafts is the largest volume it is safe to place in a single day of surgery. The limit is not the surgeon's time, it is the scalp: both the donor area being harvested and the recipient area being planted need to heal, and beyond this number the tissue is being asked to do too much at once. This upper limit is also dependant on hair type, if you have very curly or Afro-Caribbean style hair then this may be reduced considerably to closer to 2-2500 grafts
Anything above 3500 grafts is therefore planned as two procedures, split a minimum of six months apart so the scalp fully recovers between them. That is a normal plan rather than a compromise, and for extensive loss it is the only way to reach the numbers involved safely.
If you have been quoted 4000+ grafts elsewhere as a single session, it is worth asking how that is being counted. Larger single-day figures usually mean either a lower density across the area, or a graft count that includes multi-hair units counted generously.
Is 4000 Grafts Enough for the Hairline and Crown Together?
For most people, yes. 4000 grafts is the point at which treating both areas properly becomes realistic rather than a compromise between them.
A common split puts around 2500 grafts into the hairline and mid scalp and around 1500 into the crown. That gives the front the density it needs, because it is what people see first and what frames the face, while restoring the crown enough to remove the bare patch. The exact division is decided from your own pattern of loss.
What it will not do is give both areas the density of a single-area procedure. 2500 grafts spent entirely on a hairline covers about 63cm2 at full hairline density; the same 2500 as part of a 4000 plan is doing the same job across a larger area. The trade is deliberate and it is the right one at this level of loss, but it should be understood going in.
At 4000 grafts the donor area becomes the governing constraint. A lifetime donor supply is finite, usually 6,000 to 7,000 grafts across a lifetime, and hair loss carries on after surgery. Taking 4000 leaves a meaningful reserve but not an unlimited one, which is why the plan is built around what you will still need in ten years as well as what you want now.

What 4000 Grafts Looks Like
4000 grafts is around 8,800 individual hairs, because a follicular unit graft carries one to four hairs and averages about 2.2. Spread across the front and the crown, that reads as the whole top of the head restored rather than one area repaired.
Because the work is staged, the result arrives in two parts. The first session sheds and regrows on the normal timeline: transplanted hairs shed within the first few weeks, new growth begins around three months, and that session settles between nine and twelve months. The second session starts its own clock from the day it is done.
In practice that means the full result of a 4000 graft plan is around eighteen months to two years from the first procedure. It is a long timeline and it is worth knowing at the outset rather than discovering halfway through. See more before and after results from our patients, or book a free consultation to talk through what your own case would need.
Not sure whether 4000 is your number? The area is measured at a free consultation with the surgeon who would carry out the procedure, so you get a figure based on your scalp rather than an average.
How the Two Sessions Are Scheduled
The two sessions are a minimum of six months apart. Six months is the floor rather than the target, and many plans sit at nine to twelve months between sittings, particularly where the first session was close to the single-day maximum.
Both dates are not fixed at the outset. The first session is booked and carried out, then the second is planned once the surgeon has seen how the first has grown in, usually at a follow-up around the nine month mark. Booking both in advance would mean planning the second one blind.
The price is agreed for the whole plan before the first session, so the total does not change while you wait.

Frequently Asked Questions
Q: How much does a 4000 graft hair transplant cost?
A: £7,398 at My Hair UK for the whole plan, across two sessions. That is £1.85 per graft. UK clinics widely quote £9,500 to £11,000 for the same number.
Q: Why does 4000 grafts need two sessions?
A: 3500 grafts is the most that can safely be placed in one day, because both the donor and recipient areas have to heal. Anything above that is split into two procedures a minimum of six months apart.
Q: Does the price change depending on how the sessions are split?
A: No. The price is set by the total number of grafts, so 4000 grafts costs £7,398 whether it is planned as 3500 and 500, 2000 and 2000, or any split in between.
Q: Is the maximum in one session the same for everyone?
A: No. 3500 is the maximum possible, not a number everyone reaches. Very curly and afro-textured hair curves beneath the skin, so extraction is slower and more careful, and the realistic single-session maximum is often closer to 2000 to 2500 grafts.
Q: How much does 4000 grafts cover?
A: About 100cm2 at the hairline at 40 grafts per square centimetre, or about 160cm2 on the crown at 25. At this number most plans treat the front and crown together rather than one area.
Q: How many hairs is 4000 grafts?
A: Around 8,800. Each graft is a follicular unit carrying one to four hairs, averaging about 2.2.
Q: How long does the whole 4000 graft plan take?
A: Around eighteen months to two years from the first procedure. Each session takes a day, the sessions are a minimum of six months apart, and each one takes nine to twelve months to show its final result.
