Ishida still said it was a gradual process, so it wasn't caused by some sudden trauma, imho.

(I think the "bad genes" claim originates from Ishida mentioning that his hair turned gradually white.)

I personally believe that guy is imagining this. There's no way Michi, I and the Japanese fans recently discussing the causes of the change in Arima's hair color on a spoiler site missed such a tweet.
