Before my hair transplant my hair loss was at stage 7, which is the maximum stage I was told. Although the surgeon was able to extract 3200 grafts, I was left with a large area with no hair at all: temple, front and crown. There are absolutely no hairs in those areas and I now want to have a second session to cover only those areas. The danger of covering an area that already has hair graft is very low. Apart from this scenario, is there any cons for going back within 3 months?
