Query: I think this is the only thing guys can use.

I am a guy with messed up nails. I tried another Sally Hansen product but it looked like I had put polish on my nails. NOT a good look. And it did not come off. Being a guy I did not have polish remover around. "face palm". But this stuff does seem to make my nails more attractive with regular use.
