I think Kaneki reiterating in his head about getting his limbs cut off everytime he regenerated was supposed to be an explanation for us. His hair gradually started going white again when Arima mentioned he could've killed him within 2 seconds showing a lot of stress.

It may not be as logical as when it turned white in part 1 but I don't think you should be looking for everything to be logical in a fictional story.
