How graft numbers are estimated
- The size of the area to cover
- The density you want, especially at the hairline
- How much donor hair you have, and how dense it is
- Hair thickness, curl and colour, which change how full a result looks
- How your hair loss may progress in future
What is a graft?
A graft is a follicular unit: a natural group of one to four hairs that grow together. On average a graft holds around two hairs, so 2,500 grafts is roughly 5,000 hairs. Single-hair grafts are used at the front of the hairline, with larger units behind for density.
Common questions
Is a higher graft number always better?
No. Donor hair is limited, and taking too much can leave the back of the head thin. A good plan puts grafts where they make the most visible difference and keeps some in reserve.
How accurate is this estimate?
It shows typical ranges for each stage. Your own number can be lower or higher; send photos of the front, top, crown and back of your head for a personal assessment.
