Title: Why does a hair sometimes change colour as it grows longer?
Post by: ...lets split up... on 18/05/2013 21:36:49

Hi, i've been wondering for a while why some hairs are light at the root but get darker towards the tip? I was examining my sideburns the other day and noticed i am starting to grow thicker black hairs where before there were only blondy-brown hairs, thats fine, but what gets me is that some are light at the root. Aren't hairs dead? If they are turning black shouldn't it be stright from the root outwards?

Am i missing something?
