Based on the fact that the average Caucasian male has a density of 2 hairs per millimeter, it can be assumed that the average density of hair is 1250 hairs per square inch.

One reason they do not happen more is that antibiotics are given before and after the procedure to prevent infections from even starting. 9. Cysts. Cysts can come up in the areas where the hair is being transplanted to, also called the recipient areas. How loose your scalp is helps to decide how many grafts can be done just as hair density does. 4. Coarse hair will cover more area.

On the other hand, if the doctor talks about how little it will cost and how quick and easy it will be, be suspicious of that too.
