how many grafts will I need????????

Formula:

Crown Area = 3.14 X radius squared in cm (centimeters)
Frontal Area = 3.14 X radius squared divided by 2 (1/2 the area of the crown formula)
Mid-Scalp = length X width in cm


Density:

20 grafts/ cm squared = thin coverage
30-40 grafts/ cm squared = medium coverage
50 grafts/ cm squared = moderately dense coverage
