I have terrible nails and I always have to use superglue with bits of tissue to reinforce my nails.
I sometimes have to repair a broken nail with acrylic. You can buy acrylic powder along with a solvent from a beauty supply store. I dab a bit on a crack, and it hardens in a minute or so. Occasionally I will rebuild a broken nail by cutting a glossy cardboard form to fit under the nail, and brushing the acrylic over that. It's best not to coat the entire nail, as this seems to have a lasting softening effect on the nail.
