In the study, researchers used a type of human skin cell to generate new hair follicles, the structures beneath the skin’s surface that sprout hair.
Although the study is one of the first to find a way to create new hair follicles in the lab, much more research is needed to improve the technique. The hair follicles generated in the study typically did not sprout hair that could grow all the way to the skin’s surface, the researchers said.
Still, once the technique is refined, it could have advantages over existing hair-loss treatments, which typically work by slowing the loss of hair follicles, stimulating the growth of existing hairs or moving hair from one part of the body to another, called hair transplantation.
