^Well it's not technically impossible if it's give enough time, I think. If you are still young and cut all the white hair to the point where you are almost bald and let it grow from that point, then the growing hairs might get some color again if you've got enough melanin.

Since Kaneki has the unrealistic healing factor, it could be possible to turn your hair back to original in such a short span of time and without the drastic measure i mentioned above.
