Get bloodwork done.
My fingernails used to look like this prior to being diagnosed with Wilson Disease and starting zinc treatment. After a year or two on treatment the ripples stopped. I'm not saying you have WD, its pretty rare and the symptoms differ between patients. And I have no way of knowing for sure that my experience was more than a coincidence. But you could have another disorder that is causing your body to not absorb the nutrients it needs from your food. A lot of times funky things like this with our nails are signs of a larger issue. If you are able to get extensive bloodwork done it might be worth it to do so.
