New hair starts white then turns brown?

[Tominwashington]

Hi Folks,
Thanks for having me here!
I have a quick question. I am noticing many of my new hairs that are growing in previously thin areas are coming in white, but the base of the hair is turning brown so that I have quite a few hairs that are half and half(ish).
Has anyone else had this experience? If so, can you explain what is going on? I have tried to research without much success.
Thanks for everyone!
