Hello in California,Sounds like you've done all the right things to try and slow down your hair loss. Although you can get an idea of how much hair loss you may eventually experience by looking at close relatives on both your mother's and father's side, it is not a very accurate. You could still have a lot of hair loss even if your relatives don't. Having said that, if you are already 36 and just a Norwood 3V, it looks as if your hair loss may not be very aggressive, but keep in mind that the medications may also be working hard to help you.Hereditary hair loss in men starts at or right after puberty and continues from then. In some people it is a very slow on going process, and in others it goes through a rapid phase with significant hair loss in the first decade or two, and then the hair loss slows down and the hair pattern becomes stable in your 30's and 40's. It is just really hard to predict this behavior ahead of time.The bottom line is this: You will eventually lose more hair in the temples and front, we just can't be sure how much. Most of us are reluctant to treat only the vertex, unless we can be really sure that there will be no further hair loss up front. You want the largest number and best hair follicles to be saved for restoring the front hair line, the mid scalp, and the temples because most people who see you (including yourself in the mirror) will see only your front hair line and temples. The front and temples are most important for framing your face. Few people will see the vertex of your scalp. If the loss of hair in the vertex is really bothering you, you could opt to have your vertex transplanted now, but you have to make sure you save enough donor hair to eventually do the front and temples. Another thing to keep in mind is if you have your vertex grafted now, and you have further hair loss around the vertex in the next 10 to 20 years, you could end up with an unwanted halo - where you have a round area of restored hair in the vertex, surrounded by a margin of bald scalp. It looks really bad and will need a lot of hair grafts to fix. Finally, keep in mind that 9000 available donor follicles is likely an over-estimation. It is highly unlikely that a surgeon will be able to get 9000 follicular units out of your occipital scalp in multiple sessions, but you probably have a good 6000.I hope this helps you to figure out what to do.
