The investigation is progressing. Scientists recently said they may have discovered the mechanism of graying in human hair, British media reported. guardian.
According to them, by understanding the origin of this dispigmentation of the hair with age, they could find a treatment to reverse or stop the process. Men and women could thus keep their original hair color throughout their lives.

But for now, these scientists’ research has only relied on mouse stem cells, which are also found in humans. With age, these cells can no longer move during growth, which no longer allows hair color to be maintained.
“The new mechanisms raise the possibility that the same fixed positioning of melanocyte stem cells may exist in humans,” he testified in the scientific journal. Nature Qi Sun, the principal investigator of the study conducted by New York University Grossman School of Medicine.
He then explained: “If so, it presents a potential pathway to reverse or prevent graying of human hair by helping blocked cells to move back between compartments of the developing hair follicle.”
For its part, the British Association of Dermatologists (BAD) told the BBC that this “work on melanocytes could also help to understand and treat certain types of cancer and other medical conditions.”
