Hairdini,
You are correct I am in my mid 30's. I'm doing my procedure wit Dr. Keene. I am fortunate with my hair loss up to this point in my life. In fact, up until a few weeks ago I had never even taken any hair loss drugs. If I follow my fathers hair loss I will simply just have a high hair line. Both of my grandfathers also have a good head of hair.
I'm not so sure about the dense packing of 50 - 55cm2. Dr. Keene measured my healthy hair at about 35cm2. She has recommended doing the hair line with the same amount of hair per cm2. To me this would seem to provide a more natural transition to the rest of my head. My hair does have a lot of volume so maybe 35 cm2 on me will appear much fuller than 35cm2 on someone with less volume in hteir hair. I would be afraid with dense packing that maybe it wouldn't look natural. I guess if I want it thicker I can always add more later.
