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

It is normal for the scabs to flake off at 7 days post-surgery. And with them, the transplanted hair may also come off. However, the follicles should have taken root by this point and will begin to grow in about 4 months.

There isn't anything to worry about here because the grafts will shed within a week up to months. Just sit back and wait until they begin to grow. 

It is normal for transplanted hairs to shed starting about a week after surgery and continuing over the next several weeks. The hair shafts often shed along with the scabs as they loosen and fall off.  This does not mean that the follicle is lost.  The follicle should start to regenerate a new hair shaft somewhere in the 3-6 month time frame.  Patience is key.
All the best,

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.
