...given that the person's hair is mostly non-grey (if it matters at all). What i want to know is whether after having yielded a grey hair once, the new root growing out of the follicle has been 'coded with grey pigment information' for every hair that grows out of it from then on?
When an odd grey hair is pulled out of its follicle can a new non-grey hair grow out again?
Interesting question....
For that, we閳ユ獫e to set the cause first.
White hair due to physiologic cause and to pathological causes.
I think you referred to the first cause due to the aging. Well, on that case, the Melanocytes present in the follicle begin to decrease slowly (here閳ユ獨 why colour goes thro grey tonality till the white) and so every hair generated by that follicle will be white for ever!

Great answer Report It

You didn't even answer the question. She was referring to the latter cause, that is, what happens when you pull out an "odd" grey hair from a head of normal-colored hair. Will that single follicle produce another grey hair at the same exact location? Report It

First of all, you do not remove the root when you pull out a hair. The root stays in and will give another hair, maybe even two, of the same color
