Why does hair turn grey?

Why does hair turn grey as we get older? Is there anything we can do to prevent ‘greying’? 

There are several factors than cause greying of hair, smoking is one of them, as well as anemia, poor nutrition and untreated thyroid conditions.

However, what causes hair’s colour to change has also to do with the process controlling the production of the pigment called melanin, the same pigment that tans skin in response to sunlight.
