Scientists appear to have moved one step closer to a solution for hair loss. For the first time, researchers have been able to grow entirely new hairs on human skin. The new technique would be drastically different than current treatment options available for hair loss, as it would use people’s own cells to generate new hair. In the study, researchers removed cells from the base of human hair follicles and grew them in drops hanging down from the lid of a petri dish. They then injected the cells into hairless human skin that had been grafted onto mice. In five out of the seven grafts, new hair follicles grew. Further tests confirmed that the follicles were human.
