Q:

Dear 100 Hour Board,

What happened in the cell when you have a hair whose far end is white but the end down by the follicle is brown, i.e., it started out growing a white hair but then pigment "kicked in"?

A:

Dear you,

According to this Biology StackExchange question, it's probably due to something called oxidative stress. I'm sorry I don't have time to write this up for you; I've been super busy lately, and the writer who was working on your question wasn't able to finish it (they had the same idea as the person on StackExchange, though).
