How many grafts do I need?
The number depends on three things, and only one of them is your Norwood grade.

Most frontal and mid-scalp cases fall between 2,000 and 3,500 grafts. The number depends on your Norwood pattern, your donor density counted under magnification, and the calibre and curl of your hair — a coarse curly hair covers roughly twice the area of a fine straight one. A graft count quoted without a donor count is a guess.
The rough ranges
| Pattern | Typical range | Notes |
|---|---|---|
| Norwood 2 | 800–1,500 | Temple refinement. Often better served by medical treatment first. |
| Norwood 3 | 1,500–2,400 | Hairline and temples. |
| Norwood 3 vertex | 2,000–3,000 | Front plus early crown. Crown is expensive in grafts. |
| Norwood 4 | 2,500–3,600 | Front and mid-scalp, crown usually staged. |
| Norwood 5 | 3,200–4,500 | Frequently two sessions. Priorities agreed first. |
| Norwood 6 | 4,500+ | Often declined, or restricted to the frontal third. |
| Norwood 7 | — | Declined. Donor supply cannot cover it honestly. |
Those are ranges, not quotes. Two men at the same Norwood stage can need a thousand grafts apart because of donor density and hair calibre.
The three variables
1. The area to be covered
Measured in square centimetres, not described in adjectives. The crown is deceptive: it looks like a small circle and consumes grafts faster than the entire frontal third, because it is a whorl and hair has to be placed radiating outwards to look natural.
2. Your donor density
Counted under magnification in follicular units per square centimetre. Somewhere around 65 to 85 is common; below 60 the arithmetic changes considerably. This is the number that decides whether the plan is possible, and it is the one most consultations skip.
3. Your hair itself
- •Calibre. A coarse hair blocks more light than a fine one, so fewer are needed for the same visual density.
- •Curl. Curly hair covers roughly twice the area of straight hair per graft.
- •Contrast. Dark hair on fair skin shows scalp badly; matched tones are far more forgiving.
Three thousand grafts on coarse curly hair and three thousand on fine straight hair produce visibly different results. When you compare clinics, compare hair type and pattern, not just the number.
Why the first session should not use everything
If you are thirty and at Norwood 3, the loss behind your new hairline is still coming. Spending the donor area on maximum density now leaves nothing for the crown at forty-five. A plan that reserves donor supply is not a clinic being conservative to protect itself. It is the difference between looking good at thirty-two and looking odd at fifty.
The graft estimate on this site gives an indicative range in about ninety seconds. It is corrected in person, because people grade themselves roughly one stage better than they are.
