This hair loss question was answered by Dr. Glenn Charles of Florida who is a member of the Coalition of Independent Hair Restoration Physicians. His professional answer is below.
Is 10 months after the first hair transplant too early for a second one? Are there any negative things that could occur, if you have your second procedure too early? Are there any positives in waiting for a year or more to have second procedure?
At 10 months you are probably looking at 80-90% of your hair growth. It really depends on when the hair started growing. If you were getting growth at 3 months, you will be close to a final result at 10 months. If you did not start getting hair regrowth until month 4 or 5 then you may need to wait up to 1 year to get a final result. The concern in transplanting a second procedure too soon is that the doctor may make an incision in the recipient area right on top of a previously placed follicular unit graft that has not yet started growing. It is unlikely that at 10 months that this will occur. One additional benefit of waiting a year or more is that you can make a good decision as to whether you need more grafting in the original transplanted area and if so what areas need more than others.
