Hope for the Hairless

SPRINGFIELD, Massachusetts -- Scientists transplanted scalp cells from one person to another and, for the first time ever, grew new hair on a human without the use of drugs.

The results of the experiment were reported in Thursday's issue of the journal Nature.

The researchers, led by biologist Colin Jahoda at Durham University, in England, took cells at the bottom of hair follicles from Jahoda's scalp and from a colleague's and transplanted them into the forearm of Jahoda's wife.

Within five weeks, the transplanted tissue made a total of five fully grown hairs in the woman's arm.
