So, what exactly causes those? A lot of people say it's due to zinc deficiency, but I've read somewhere that it was rather provoked by small traumas to the nails and such. Who should I believe?

Causes what? That scuff mark looks like you took a knife and scratch off a thin surface layer.

Can be either (or vitamin B6), also some people just get it due to genetics.

Now I'm not an expert but why can't it be both?

Maybe bruises cause those easier for people who have zinc deficiency.

Frequent masturbation (for men) causes zinc deficiency, which in turn causes those marks to form more easily when you hit your hands.

I'm pretty sure it's like a bruise under your nail. Experiment, choose a finger with none of the white marks, choose a part that is visible and take a pointed thing like mechanical pencil tip and just mash hell out of your finger. Should hurt and be red. Don't puncture nail though. Wait a day or two and see if it becomes white. I've tried this and Im very confident that's all it is
