Q: Why is hair loss in women harder to treat with hair transplants than hair loss in men?
A: The majority of women present with diffuse hair loss (i.e. thinning all over) rather than the patterned hair loss seen in men (where the hair is localized to the front and top of the scalp).
Diffuse thinning presents two problems for a potential hair transplant candidate.
The first is that there is no permanent area where the hair can be taken from. If hair is taken from an area that is thinning, the transplanted hair will continue to thin after the procedure, since moving it doesn’t make it more permanent.
The second problem is that since the areas to be transplanted are thin, rather than completely bald, the existing hair in the area of the hair transplant is at some risk to shedding as a result of the procedure.
NY Japion — a weekly newspaper in the Japanese language, published in the New York tri-state area, and distributed for free in the Japanese community — has featured Robert M. Bernstein, MD, in their series on hair loss in men and women.
