Q: I have seen through forums that a hair transplant gives severe shock loss in the donor zone (especially behind ears) after the surgery. Doctors say it is temporary and can last about six months or more. Frankly, do you believe in this? Will the donor shocked hair recover? — M.D., Darien, C.T.

A: It depends if you are speaking about follicular unit hair transplantation using strip harvesting (FUT) or Follicular Unit Extraction (FUE). With FUT, it is extremely uncommon to have any shock hair loss in the donor area. This could occur if the hair transplant procedure was done improperly, i.e. the donor area was closed too tightly. In this case, some hair loss may be permanent. This is one of the reasons that very large hair transplant sessions are unwise. Shock hair loss in FUE is more common, but is generally not significant and should eventually recover completely.

That said, some shock hair loss in the recipient area is quite common with either hair restoration procedure (FUT or FUE). This is particularly the case if there is a lot of existing miniaturized hair (hair that is starting to thin) in the transplanted area.
