That actually succeeds in getting a somewhat indignant look from Shrike.

"I wash it when I bathe!"

He just didn't have reliable access to nice things like combs or brushes for some time before arriving in Johto. But he definitely did the best he could with what he had.

It's when that last remark fully registers though that his self-consciousness kicks in again. Not in regards to the hair thing (well, okay, maybe a little to do with that) but the... everything else. Shrike quickly looks away, starting to pull up the hood again.
