How many grafts for your hair transplant?

Click the areas that concern you, say how much hair is left, and see a range of grafts and hairs straight away. Then compare the starting prices of each technique at our partner clinics.

No registration Instant results Illustrative estimates

A planning example, not a diagnosis. Areas, densities and hair mixes are illustrative assumptions pending clinical validation. The diagram does not measure your scalp or determine transplant eligibility.

01Which areas concern you?

Select one or more areas on the diagram or using the buttons.

Numbers 1–7 match the drawing and the result breakdown. Parts bearing the same number form a single zone and are counted only once.

02How much hair is present?

A common setting for all zones; changing it reapplies this coverage everywhere. Refine individual zones below afterwards. Retained densities are assumptions.

Mildly thinningAssumed retained density: 20–25 FU/cm² Significantly thinningAssumed retained density: 10–15 FU/cm² Mostly bareModelled without retained hair: 0 FU/cm²

03Adjust the planning assumptions Area example

Norwood examples select all areas and “mostly bare”. They do not classify your hair loss. VI uses 210 cm² (over 200); VII uses 230 cm² (over 220). Actual areas vary.

Whole example area (cm²) 200 cm²

80–240 cm² for all seven zones together. Zone 1 retains an illustrative area of 20 cm². The remainder is split between corners (10%), frontal zone (20%), anterior and posterior mid-scalp (20% each), vertex (25%) and posterior band (5%). These proportions are not measured from the drawing.

Target density behind the frontal areas

Zones 1, 2 and 3 add 5 FU/cm² to the chosen band. Assumed retained density is subtracted from the total target. Changing this setting reapplies the band to every zone.

Appearance guide, not a guarantee: below 25 FU/cm² may look sparse; around 35 may give more coverage while scalp remains visible in light; 40–45 may look fuller. Hair calibre, curl, contrast, styling and growth change the result.

Assumed mix behind the single-hair strip

The 20 cm² frontal strip uses single-hair FUs. Behind it, 2-, 3- and, if available, 4-hair FUs contribute to the total. This simplified mix is not an assessment of your donor hair.

Theoretical demand, not a prescription or a promise of growth. The hair estimate counts transplanted hairs, not guaranteed surviving hairs. Donor capacity may be insufficient, particularly for extensive loss.

01 / UNDERSTAND

Grafts ≠ hairs

A graft is modelled as one follicular unit (FU). Single-hair units form the frontal strip; units with more hairs increase the hair total behind it. The real mix depends on the donor area.

02 / PRESERVE

A limited donor supply

A large area can generate a high theoretical graft requirement. This does not mean enough grafts can be safely harvested. A doctor must assess supply, priorities and long-term hair loss.

03 / PERSONALISE

Medical assessment matters

Real area, retained density, hair characteristics, the cause of loss and medical history must be evaluated. Density alone cannot predict the appearance or suitability of a transplant.

YOUR QUESTIONS

Before you go further

How to read your estimate.

How is the estimate calculated?

For each area: example area × (target FU/cm² minus assumed retained FU/cm²). Negative differences are set to zero. Minimum and maximum values are summed. Frontal areas add 5 FU/cm² to the target. Hair totals use 1 hair per frontal-strip FU and the selected mix elsewhere; they do not include existing hairs.

Why are Norwood VI and VII estimates higher?

These examples model extensive bare areas: 210 and 230 cm². At a uniform 35 FU/cm², these areas alone imply 7,350 and 8,050 FUs. Higher frontal targets raise demand. These are coverage examples, not standard areas for every Norwood stage or a safe harvest recommendation.

Can I choose different coverage for each zone?

Yes. Open “Refine coverage and density by zone”. All parts with the same number share a setting. Changing a common setting reapplies it everywhere. Areas and densities remain assumptions requiring medical confirmation.

Does 40–45 FU/cm² guarantee a good result?

No. These bands express illustrative visual goals, not guaranteed outcomes. Hair thickness, curl, colour contrast, graft growth and donor limitations all affect the result.

Do I need an account to see the result?

No. Results appear immediately without registration or photos. The assessment button opens Hairmed’s existing enquiry form.
