Mine are vertical

From the moon to the tip would be vertically. It can be a sign of zinc deficiency. I have them too.

I have them, could be an MTHFR gene mutation.

Can also be caused by cysts in the fingers under the skin that put pressure on the newly forming "nail".

I found the cause for me to be parasites. The infection was coming out from under the fingernail beds when I started a serious parasite cleanse. I had ridges on most of my nails.
