To some of you who don't know why Kaneki's appearance changes after his torture, this is the discussion for you! (Sorry for the cheesy introduction)

His hair turns white because if the intense stress put on him. One can argue that hair shouldn't turn white in an instance. You are correct, but there are some people who don't know exactly how long Kaneki was tortured. He was tortured for 10 days, enough time for his hair to turn white. This misconception probably arose because in the anime(for those who only watched the anime) it turned white in a few seconds. I have heard theories about how this was the effect of Marie Antoinette syndrome, I partly agree. I think his hair turning white was the effects of intense stress AND the syndrome.

Now for the explanation for the black nails. No, Yamori did not paint his toenails. Kaneki's nails turned black because of his blood. Before you give up on me, please read on. His nails turn black because his nails died and the blood, below his nail, were trapped there and dried. Now before you say, "If that's the case, then why doesn't regeneration fix that problem," let me explain. Because of Yamori's sloppiness and impatient, he forced the cut nails/fingers to regenerate faster. Causing the nails to not regenerate properly.

Well, that's all I have to say! So please state your opinions and ideas. I would love to see your opinions.
