WHY HAIR TURNS GREY

Each of our hairs is fitted into a tiny sheath or pit in our skin. In this pit grows a small bulb, which is really the root of the hair, the bulb drawing on a network of minute blood-vessels which maintain it. The hair itself is in tho form of a little tube, the shell being covered with tiny scales and the tube being filled with a colouring matter which is nourished by the blood drawn up. from tho bulb below. When , the system becomes enfeebled either by age, by illness, or by intense nervous strain, it follows sometimes either that tho bulb actually dies (in which case no hair can grow in that particular “pit” again), or the blood-vessels can no longer keep up the supply of nourishment for the colouring matter in the tube of the hair, in which case the person becomes grey. It Happens, too, that tiny cells from other parts of the body will sometimes grow into the hair, driving out the colouring matter and replacing it with a little bubbio of air, which lias the effect of turning the hair gi(py while it is still perfectly healthy. : .
