|Normal density of hair is in the range of 90-100/ cm².However, some individual have lesser and some greater density than this.|

Doc, what are the methods to calculate the number of grafts I shall require?
- Well, you have to have a mathematical background to do that. Take a sheet of thin transparent plastic. Place this on your bald spot and trace out the margins where normal hairline starts. Place this on a centimetered graph paper. Calculate the area in cm². Now, multiply this with 45. This shall give you the exact number of grafts you shall need.
- You can make use of the graft calculator above. This is however not accurate since the size of the head is different in different individuals. The accuracy is ±20%
- A visit to Darling Buds is the best way to know the exact number of grafts that you will need and the number which can be safely harvested.
