A Graft Range, and Why It Is Not Your Graft Number

It gives you an order of magnitude, not a plan. It works from the pattern of loss alone, and the single most important variable in a real graft number is your donor density, which cannot be estimated online. Treat the output as a range to help you budget and sanity-check a quote, not as a figure to hold anyone to.

Because two people with visually identical recession can have very different donor supplies, and the safe graft count follows from what the donor can spare rather than from what the bald area would like. Any figure produced without that measurement is arithmetic, not a plan.

A standard classification of male pattern hair loss, running from minimal recession through to extensive loss with only a band of hair remaining at the sides and back. It gives clinicians a shared vocabulary for describing a pattern. Our guide to the Norwood scale explains each stage.

Not well. The Norwood scale describes male pattern loss, and female hair loss is usually diffuse rather than following those stages. More importantly, women frequently have a treatable underlying cause and are often not surgical candidates at all. Start at women's hair loss treatment instead.

No, and this distinction matters when comparing quotes. A graft is a follicular unit, the natural grouping in which hair grows, and it contains anywhere from one to four hairs. Two quotes for the same graft number can therefore deliver noticeably different amounts of hair.

Because coarser hair covers more scalp per hair. Someone with thick, coarse hair achieves the appearance of density with fewer grafts than someone with fine hair, for the same area. Curl helps too, and a low contrast between hair colour and skin tone helps considerably.

It could mean your donor cannot support the full number and the clinic is planning sensibly, or that the plan covers a smaller area than you assumed, or that it is staged. Ask them to explain the basis. A lower number is not automatically a worse plan.

It is worth asking about. Ask specifically how the graft number was calculated and what donor density was measured. An inflated count costs money and spends donor hair you cannot replace, so a clear explanation matters more than the number itself.

No. The limit is what your donor area can safely give across your lifetime, not what the recipient area could accept. Taking more than the donor can spare thins it visibly and permanently, and there is no way to reverse it.

Not always. Larger plans are frequently staged across two procedures, which protects the donor and often produces a better long-term result. Whether staging suits you is a decision made at assessment.

It cannot, and this is one of its more significant limitations. A sensible surgical plan reserves donor supply for loss that has not happened yet. A number based on today's pattern alone can be an overestimate of what should be spent now.

By being examined. Donor density is measured directly, the recipient area is mapped, your pattern is staged and its likely progression considered, and the number comes out of that. You then receive it in writing as part of an itemised estimate.

No, and assuming so is how people are sold inflated counts. The right number is the one your donor can support, placed well, in the area that matters most. More grafts placed badly, or taken from a donor that could not spare them, is a worse outcome.

Cost follows the graft number, but we do not publish a per-graft rate, because a rate multiplied by an unexamined count is exactly the arithmetic this page is warning you about. See our cost guide for how pricing actually works.
