Peeling nails and thin nails!

My nails are so thin and you can see the ridged lines on them. They always peel, I’ve tried strengtheners, nail oils etc and nothing seems to work!

I also wear gloves when I’m washing dishes and use a hair scrubber in the shower so I’m not scrubbing with my nails.

Does anyone know why they’re thin and always break/peel?

Also, if they grow, they either break or go thin.

I take vitamins that have 15mg of iron in them everyday too.

Please helps it’s painful 😣
