Is my Hair Transplant Ruined? Some Grafts Disappeard After 6-7 Days?

The follicles integrate rather quickly.  Then, the hairs will fall out with scabs from a few days to a couple weeks.  It may be a year of more before the hairs regrow.  Hang in there!  Check in with your doc if you still have concerns.

Disappearing grafts does not mean your hair transplant is ruined.  You must understand that even in the most ideal circumstances you will lose a few grafts.  Even if you don't lose any grafts, not all the transplanted grafts will grow out.  Nothing is 100% except as they say death and taxes.

Its perfectly normal for the implanted hair to "disappear" and lead to anxiety post op. The implanted hair follicles remain intact and then go into a dormant phase which lasts through one hair cycle.. You should see new hair grow after around 5 months. All the best.
