Grafts requirement can be calculated by first calculating the area to be coverd in square centimetres. simply put a transparent sheet of plastic paper on bald area mark the area to be transplated with a marker. Now simply make squares with side 1 cm with a ruler and count these squares. This is total area of baldness in square centimetres.
Calculate grafts by multiply ing this area with
15 to 20 for a light to moderate density.
20 to 25 for moderate to mild heavy density.
35 to 60 for a very high density.
Approximately 1500 to 2000 grafts are needed in front one third area for a good density.
2000 to 2500 grafts are needed upto middle half of head.
2500 to 3500 for upto crown and
4000 to 5000 for covering whole head in moderate to mild high density.
