Thinning of Transplanted Hair

How big of a problem is the gradual thinning of transplanted hair — have you seen cases where a transplant looks decent but then some years later looks crummy because it thinned out too much?

In about 30% of the male population, men will lose some of the hair we call permanent hair from the sides and back of the head. If that would have been you, then you might lose hair in the transplanted area. There are other causes of hair loss, so seeing a good doctor should help you with the diagnosis. I would want to look at your donor hair and see if there is significant miniaturization in that area. With loss of donor hair, we should see some miniaturization in the donor area.
