Healthy Nails?

My finger nails are growing longer than they ever have, and it's the end of winter. Usually in the winter, my nails are brittle and break really easily. I'm shocked at this new phenomenon. Am I supposed to actually trim my nails? Never a worry before, because I just waited for them to break, which they did with consistency. They're getting really long. Not fake nails long, but long. On the verge of nuisance.

I've changed a number of things, and I'm not sure which one has improved my nail health. First, the diet. 90% vegan - lots of quinoa, rice and vegetables. I haven't drunk cow's milk in over a year - so much for the old teaching that milk helps your nails grow. But I started drinking almond milk, which has more natural calcium than cow's milk, about a month ago. A month isn't really long enough that I should be seeing results already from that increased calcium intake, but maybe it's possible.

Second, no nail polish. I had this weird experience where a nail polish made my fingernails hurt, after I took it off. I figured that couldn't be good. I'm not sure if it was the polish or the remover, actually. After that I decided to stop polishing my fingernails. That was about 6-10 months ago.

Third, changed to body oil instead of lotion. I think the body oil may be getting on my nails inadvertently. Since they're not polished, the oil probably soaks into my nails a little bit. I have a theory that this could be improving their resilience. Who knows?

It's cool to accidentally have long nails, is all I'm saying.
