How can hair change colour along its length?

Anna Hoad asked the Naked Scientists:
   
Dear Chris

I searched through your wonderful website but couldn't find an answer to this:

My hair is naturally black, undyed and long enough for me to observe changes in the colour.

Some of my hairs are colourless for several inches at the ends for but appear to have regained their black colour towards the root.

How can this happen?

Anna Hoad

What do you think?
