Do I even care?
Ha! So what if I'm going white? I've never been normal, why start now and worry about this? It would be kind of cool too. But I would still worry that it would take forever for my whole head to turn white, it would be patchy at first. Goodbye sneaking in as a student, having my ID checked outside pubs or having compliments paid to my long red hair by strangers.
Realistically, its probably just one hair without pigment. I'm not going white just yet, I drink too much tea to be stressed.
