Q: My hair loss resembles the grade I female hair loss scale, but none of the male hair loss patterns. It has been relatively stable for the past five years and only recently has it begun to progress further. I began both Propecia and Rogaine two months ago, but the hair loss still continues at the same pace. I’m really worried. Does a hair transplant work in such a diffuse hair loss? — D.D., Park Slope, Brooklyn

A: If your hair loss is diffuse only on top, then a hair transplant will be effective. This condition is called Diffuse Patterned Alopecia or DPA.

If the diffuse pattern of hair loss affects the back and sides as well, then surgical hair restoration should be avoided. In this case (called Diffuse Unpatterned Alopecia or DUPA) the donor area is not permanent and the transplanted hair will continue to thin over time.
