Why is black hair white near it's root if pulled out?

[Dims]

I have noticed that if single black hair is pulled out from skin by pincers, it appears to be white near the thick root. I.e. the black color is appearing far frome the hair root.

 

Does this mean that coloring pigment is generated far from the place, where hair material itself is generated? Or this means that pigment undergoes some sort of maturation during the grow?

 

Thanks.

I think it is because you pull out more than just the hair. The root is not just the very bottom... as you can see in the link, quite a long part of the hair is inside the skin, where it is being formed.

So, where does pigment applied to the hair on your picture?
