I have and always have had fingernails that bend. Yes, they really bend. I can push down on the end of them and they will curve. They are not brittle. If I apply nail polish, they get weaker. If I rub babyoil into them they seem to be stronger, but not enough that I could say for sure.
I know that when they are wet, they get weaker. If I have a lot of work to do with water, I generally wear gloves anyway.
Any ideas what I can do to make them stronger? I don't want great long fashionable nails, but something that at least goes to the end of my fingers would be nice.
