What would it take to dislodge or damage a hair graft 14 days after a hair transplant?

Great question! Very little can damage grafts at this point, but keep in mind the study did not take into account factors such as traumatic injury that causes significant bleeding (hitting your head on the kitchen cabinet or car door). It is unlikely to cause damage but this has never been addressed.All in all, at 14 days grafts are quite secure and the risk for loss from most external forces is extremely low.

It is important to be careful for the first week after hair transplant to make sure they don't dislodge. However after two weeks, they should have settled.
