Oxidizing amines

This has bugged me since I was looking at decarboxylating tryptophan and its come up again!

p-phenyldiamine is used in hair dyes - it is colorless in its unoxidized state, but on absorption into the hair it readily oxidizes (have too look up if the hair is some kind of catalyst).

What, then, is the product of oxidized p-phenyldiamine, or any amines? I don't understand that... Would the salt be an oxidation state?

WOW!

Quite the far cry from what I was thinking, check out the first structure on this paper if you're interested.

Even phenol oxidizes in the presence of air, IDK how it is possible, but the light-violet color is nice :D
