"Today, surgeons are able to harvest and reimplant as few as two hairs at a time, making the transplants look more natural. Still, the supply-and-demand problem remains. In the early 1990s, Colin Jahoda, a researcher at the University of Durham in England, took a step toward solving it. He stripped a few cells off the root of a mouse's whisker follicle and implanted them into its ear. Out grew a whisker. Next he took a section of follicle cells from his own head and implanted it between the fine, pale hair on his wife's arm. A thick, dark hair emerged, complete with male DNA. This demonstrated that the cells at the base of a follicle can and do regenerate into self-contained, preprogrammed hair factories."Saturday, January 19, 2008
