Norwood 4: how many grafts do you need?

What Norwood 4 looks like

At Norwood 4 the temples have receded further than at stage 3, and the front of the scalp is bare or sparse. The crown has also started to thin or go bald. What defines this stage is a band of moderately dense hair that still runs across the top of the head, separating the front loss from the crown.

That band matters, because it helps frame a restored front and gives the top of the head some cover even before surgery.

Typical graft range

A Norwood 4 plan that restores the hairline and the frontal forelock usually needs about 2,500 to 3,000 grafts. That matches the graft plans reported for this stage in a 2020 study in the Journal of Cutaneous and Aesthetic Surgery, which focused on the front hairline and forelock area.

Treating the crown as well takes more. In a study of 820 men with more advanced loss, treating the crown alone averaged 2,770 grafts, so a plan covering front and crown at stage 4 can add up quickly. At about 2.5 to 3 hairs per graft, 3,000 grafts is roughly 7,500 to 9,000 hairs. See our graft guide for other stages and our page on the cost of 3,000 grafts for pricing.

Is one session realistic?

For the front, often yes. Many people at Norwood 4 have one session of 2,500 to 3,000 grafts focused on the hairline and forelock, then decide on the crown later once the front has grown in.

Treating the front and crown together in one session is possible for some people with a strong donor area, but it spreads the grafts more thinly, and the crown is where future loss is most likely. Many doctors prefer front first and crown second. Our crown hair transplant page explains why.

FUE or FUT at Norwood 4

Both methods can supply 2,500 to 3,000 grafts. FUE takes grafts one at a time and leaves small dot scars spread through the donor area, so it suits people who keep their hair short at the back. FUT removes a thin strip of scalp and leaves a single line scar that is hidden under hair of moderate length. The choice depends on your donor density, how loose your scalp is, how you wear your hair and how many grafts you may need in future.

Because Norwood 4 often progresses, the long-term donor plan matters. Some doctors combine methods over a lifetime, using FUT and FUE at different times to get more grafts from the same donor area. See FUE vs FUT for the trade-offs.

Recovery is similar to smaller sessions, with scabs clearing at about one to two weeks, although a larger session can mean more swelling in the first days.

What changes the number

• Whether the plan covers only the front, the front and mid scalp, or the crown as well
• How dense you want the result, and how much existing hair remains in the band across the top
• Donor density and hair calibre, which set how many grafts can safely be taken
• Your age and how quickly the loss has progressed, which affect how much donor hair to keep for later

What to discuss with the doctor

• What exact area will this graft count cover, and at what density?
• Should the crown be treated now, later or not at all?
• How many grafts do you estimate I have in total, and how many will be left?
• How will the result look if I progress to Norwood 5?
• Would medical treatment help protect the hair I have?

If the band across the top is thin or broken, compare your pattern with Norwood 3 and Norwood 5. If you are not sure surgery suits you, our page on whether you are a candidate can help.
