I had a hair implant of about 2,400 follicular unit extraction (FUE) grafts febrery 2011. New hair is now visible in the frontal area, but it is sparse and I'm unhappy with the looks. Though most of the grafts were put in the frontal area of head, where so far I haven't seen any growth or changes. I'm now near the 6th month after surgery. What can I expect from this point on? What are my chances of having further improvement?
