Thank you for your positive comments. In the future with new patient postings I will be giving more information. But the photos I have posted were just a way to give the community an idea of what my results look like.

I am going to give a brief answer to the questions of what type of densities I strive for and what goals I attempt to achieve in hair transplantation. As Bill and Cousin-It pointed out, there are many factors that go into deciding what density a doctor will chose to use in a surgery. I also need to point out that when speaking of density there are two types of densities to consider. The density of FU/sqcm and the density of actual hairs/sqcm. If I plant a density of 30FU/sqcm of 2 hair FU's I will get 60 hairs/sqcm. If I plant the same density with 3 hair FU's I will get 90 hair /sqcm.

All this said and done, I would say that in a typical surgery my density ranges from 25 to 45 FU/sqcm. In general my goal is to recreate a density gradient that looks natural and imitates nature. The same density throughout the entire recipient area often creates a diffuse unnatural look that is see through. I try and create higher densities in areas of greater aesthetic significance such as the frontal tuft area, the area right behind the transition zone of the hairline, and in the central core.

To accomplish this goal I plant one hair FU's in the hairline at lower densities to give a soft, natural look. Behind the hairline, in the temperal area and the beginning of the central core area I plant the two hair follicular units with a density anywhere from 30 to 45 FU/sqcm.
Behind the 2 hair FU's I will plant the 3 and 4 hair FU's in the central core. The 3 and 4 hair FU's differ in size depending on each patient's hair and skin quality. In some patients the 3's will fit into a .8mm incision and I can plant them closer together. In other patients the 3's need a 1.0mm incisions to fit properly and I have to place them further apart. The 4's usually need a blade .1 to .2 mm larger then the 3's. I would say in general I plant the 3 and 4 hair follicular units in a density form 20 to 35 FU/sqcm. Remember, if I plant 4 hair FU's at 25FU/sqcm that is 100 hairs/sqcm as opposed to 2 hair FU's at 25FU/sqcm which would be 50 hairs sq/cm. To put it another way by planting 4FU hairs at a density of 25FU/sqcm I am getting the same number of hairs as planting 2 hair FU at a density of 50FU/sqcm. As you can see I create the higher densities by placing incisions closer together( i.e my incision density can ranger from 25-45 or more), and by selectively choosing to use a greater population of the 3-4 hair grafts in areas I want the greatest density

I know you all will be wondering how many 1,2,3 and 4 hair follicular units I usually get in a session. It varies from patient to patient. I will post my numbers of 1,2, 3, and 4 hair FU's in my future.
The patient I transplanted last Friday will give you an typical example of distribution. On Friday's patietn I got a total of 2595 Follicular Units. That broke down as follows:
Type # Grafts # Hairs
1 Hair FU 510 510
2 Hair FU 1465 2930
3 Hair FU 818 2454
4 Hair FU 175 700
Total 2959 6594

For the hairline in this patient I used 400 one hair FU's. I doubled the rest of the one hair FU's to make them into 2 hair FU's to get more density behind the hairline.

I hope this helps answer your questions.
