They appear more or less later depending on the person, they are the obsession of some but are assumed by others. Researchers at New York University’s Grossman School of Medicine may have found the reason for white hair, pointing to a potential treatment, reports The Guardian.
The study was performed on mouse and human skin cells, melanocyte stem cells. Located in the follicles, they move from one compartment to another during hair growth. But with age, these cells are less and less mobile and therefore lead to graying. The discovery, attested in mice, must now be confirmed in humans.
“A potential pathway to reverse or prevent graying”
According to scientists, hair color therefore depends on the ability of groups of melanocyte stem cells to move from one compartment of the follicle to another continuously. Except that when the hair ages, it remains in its primitive state of stem cell in the compartment of the “bulb of the hair follicle” and does not move any more.
“The newly discovered mechanisms raise that the same fixed positioning of melanocyte stem cells may exist in humans,” explained lead researcher Qi Sun. And to add: “If so, this represents a potential avenue to reverse or prevent graying of human hair by helping blocked cells to move again between compartments of the developing hair follicle. “What to make the complexes disappear in some?
