There are special cells called melanocytes which create the melanin that pigments the skin and hair. For some reason, the hair melanocytes will die off, leaving the follicles unpigmented. (Air bubbles can also get into the hair shaft and block the melanin.)

There is most likely a genetic component to this - My mother and brother both went grey early, and it's a fairly common occurance in the Welsh.

Human have a lot of oxygen in their body. When they become older, this oxygen will go, for example, in your hair, like little bubbles of gas.

Those bubbles causes the grey-white look in your hair.
