How long does transplanted hair last

When asked if transplanted hair will last, I always tell patients that transplanted hair will last as long as the hair in the back and sides of the head, which generally last a lifetime. However, transplanted hair can undergo senile alopecia and I have occasionally seen people’s transplanted hair thin out many years after the transplant but this is very rare. Generally, you can expect transplanted hair to last well into your senior years.
