Dry blood on my head. Is this normal or is the graft dead?

It is best to ask your surgeon about post operative care as each doctor has their unique regimen.  There is no clear way to tell if you lost a graft.  Bleeding is one sign that you may have lost a graft.

Some oozing is normal around hair grafts which can be responsible for crusts.  However, it is best to have this checked by your surgical provider to ensure that the graft is viable.  Best Dr. Anil Shah

It depends. Definitely the graft moved its position and this is why you had bleeding. However it doesnt necessarily mean the graft is dead. Try to go have a follow up with  the  clinic that performed the surgery so they can check your grafts out.

Immediately after your transplant your grafts are delicate. It is difficult to know whether the dried blood is because one the grafts has come out following a sleep or whether it is just bleeding from the insertion. I would suggest you visit your surgeon to put your mind at ease. 

Usually bleeding from a graft site indicates a loss of the graft. A loss of a single grafts should not be a concern for you as many more are there
