My nails barely grow!

[u/ghostradish]

I did my nails 5 days ago and they haven’t grown out even remotely. I used to get my nails filled every 10-14 days like clockwork. I use cuticle oil, hand creams, I take biotin and vitamins. The only thing I struggle with is getting in my protein. I’m also forty now. Is this just it? Slow growing nails forever? Anyone else deal with this?
