Big fingernails have stripes and two big toenails. The right big toe nail is obvious, and the front end of the nail is rotten. Please tell me what's going on!

It is normal to have horizontal stripes or protrusions on your nails. This is not a disease or onychomycosis.

The intake of calcium in human body has a great relationship with nails, and there are many other elements needed for nail growth.

When the elements needed for nail growth are not satisfied, they will be directly displayed on the nails, and this will happen. This also shows that your diet structure is unreasonable and needs to be adjusted.

But it doesn't matter, when the elements it needs reach normal values, it will return to normal and become bright, flat and shiny.

When the new nails grow, cut off those with lines and rotten ones, and all the problems are solved, and the new ones are beautiful.

I hope you can accept my answer. Thank you.
