I an not following you. What is the problem? Why not let it grow out and see how it looks before deeming it a failure?
Dont take this wrong but sometimes your hair problems aren't hair problems. Sometimes is unhealthy views or expectations of oneself. Say you put 4000 grafts into your hairline, would that make you happy? Probably not.
Try having a positive outlook. Having a natural look is infinitely more important than big time density. Putting 4000 grafts in a hairline will never look natural.
Try not to worry, give it a year, and take pics of your results so you can get honest opinions.
