Researchers at the University of Texas Southwestern Medical Center were studying a disorder that causes tumors to grow on nerves when they discovered an explanation for balding and hair going grey.
It centers around a protein called KROX-20 that creates a stem cell factor necessary for hair to hold its colour.
Researchers removed the KROX-20 from mice, which in turn became bald. When the SCF was removed, the hair on the mice in the study went grey.
The study has yet to be conducted on humans so those hoping to see their grey go away or to make hair out of thin air may have to wait awhile.
