I read somewhere that the hair bulb contains stem cells. I also read that you can transplant body hair (follicles) into the scalp and it eventually grows to be full length scalp hair. So, why do we we deal with transplanting the follicle when stem cells from a pulled hair can regrow in the scalp? (or do the stems cells on the hair bulb need to be grown in a lab before transplanting?)
