i think you can go either way. It certainly is easiest for you to simply try a scar revision first in the Bay area because there are no really good FUE physicians in the Bay area. There are some novice individuals, however. There are some good hair transplant physicians, however. Provided you find a good one, and you do not plan to wear your hair really short, you might be fine going with the scar revision first. i'd make sure they limit the amount of normal hair bearing skin that they remove. This way you will minimally distort the direction of hair growth and waste the least amount of normal hair. Wait at least 6 months to evaluate what you get from the scar revision. For the first 3 months, the scar will be very fine and you will think you are home free. then close to the 3rd month, the scar will begin to widen. If you get lucky, you are done after the scar revision alone though you will not be able to shave your head. if you are not finished, you can start with FUE at that point.
the risks associated with going with the scar revision first are that you will see no improvement, the scar will widen, or that the scar will change from white to pink or red in color. If the color changes from white to pink, you are going to have a new problem to contend with. The other risk is that the scar revision will distort hair growth angles, but if you limit the total width of the excision, i think this risk is very low.
Of course, you can simply put FUE in the scar, but given your location, you might want to start with a scar revision first and see how far you can go with this alone. the other rationale for this is that you might need more than one pass with FUE to get to a point where you can wear your hair really short. That is the only real risk from FUE alone. Multiple trips to a good FUE physicians are something to consider when you are looking into scar treatment with FUE alone.
