A study suggests baldness cure is rooted in stem cells.
(FOX News)- An inability of stem cells in the scalp to develop into the type of cells that make hair follicles may be an underlying cause of male-pattern baldness, according to a new study.
The discovery gives hope that people who are bald could regrow their hair with a future treatment, said study researcher Dr. George Cotsarelis, a professor of dermatology at the University of Pennsylvania.
In people who are bald, hair follicles have shrunken and become microscopic, Cotsarelis said. And scientists long thought that bald people also had a depletion of hair follicle stem cells, which are necessary to grow hair.
