Why does our hair turn grey as we get older?

Discovering your first grey hair can be quite the shock. After all, it marks the onset of an irreversible change. And the fact that it’s a natural process is often of little consolation. The culprits, if you want to think about it like that, behind our hair turning grey are the melanocytes contained in each of our hair follicles. These cells contain melanin, which is the natural pigment responsible for our hair colour, whether that be brown, blonde, black or ginger.
