Paul, I understand your feelings, but it may be worth knowing that, LONG before chemotherapy, and even after synthetics were available, the best and most expensive wigs have always been made of real human hair. Read O. Henry's story, "The Gift of the Magi", for a wonderful twist on this.

Aloha,
Mark
