Hair Transplant Maping For Costing

What is Hair Density Calculation?

Dr. Behnam calculates the density (number of grafts per centimeter) in the donor area and determines how many grafts he can remove in one session. Most people have between 40 and 80 grafts per square centimeter in their donor area. In the initial meeting, Dr. Behnam calculates the patients’ density in the donor area which will ultimately determine how much of the bald areas can be covered in a single procedure. A person who has 80 grafts per square centimeter will have more grafts to transplant than the person who has 40 grafts per square centimeter in the donor area, and thus a greater balding area can be covered. These measurements give the patient a realistic expectation of what can be accomplished in a single hair transplant procedure. Often, patients with lower density count realize they can not achieve the results they want and decide not to do the procedure. This is very important. You could only figure out whether you have a poor density by having a density calculation done prior to the procedure. We feel that this is the most ethical way to inform the patient of what to expect.

What is Hair Mapping?
Dr. Behnam maps out how many centimeters of balding areas are needed to be covered on top of the scalp and the number of grafts that are needed. This is done by placing a square centimeter grid over the patient’s head and outlining the area to be covered. The area can then be measured. Please look below for an example of the hair mapping grid. If the area to be covered includes the front and mid scalp area, 25 grafts placed per square centimeter are required to give adequate coverage. Also, if a new hairline needs to be created, 400 grafts are usually required for the hairline (actual amount may vary depending on the size of the patients head). If the area to be covered is the crown area, 35 grafts per square centimeter is required to cover the area. The crown requires more grafts because it is normally viewed from the top looking down revealing the space between each graft. So, lets say the hair mapping process has indicated that a patient has 50 square centimeters to be covered in the mid scalp area and also needs a new hair line. We would multiply 50 times 25 to determine that the patient needs 1250 to cover that area. Add 400 grafts for the hair line and we determine that the patient needs 1650 grafts to fill the area with adequate density.

The hair mapping grid enables Dr. Behnam to calculate how many square centimeters you need to fill and thus how many grafts you require for the entire area. The drawing on the grid indicates the bald area needed to be covered with hair.
