Graft calculator: how many grafts do you need?
Choose your Norwood stage and the areas you want treated. The calculator gives an indicative range for how many grafts are typically needed. It is an estimate, not a diagnosis.
The calculation is indicative and does not replace an individual assessment. The real number of grafts depends on the thickness of your hair, your donor capacity, the density you want and the surgeon's plan. Always obtain a concrete quotation after a consultation.
