Q: I underwent hair transplant surgery several years ago and was pleased with the results. However, over the last 2-3 years I’ve lost hair in the donor area with subsequent loss of hair in the transplanted area. Is this type of hair loss especially difficult to treat? What accounts for hair loss from the back of the head that is typically considered “permanent”?
A: Less than 5% of patients have unstable donor areas i.e. where the back and sides thin along with the front and top. We call this condition Diffuse Unpatterned Alopecia or DUPA.
It is best to identify this condition before hair transplant surgery is contemplated as people with DUPA are not good candidates for hair transplantation.
The diagnosis is made using densitometry by noting high degrees of miniaturized hair in the donor area.
At this point, I would use medications such as finasteride.
I would not do further hair restoration surgery.
