Try to add a layer of nail polish every 3rd day. And if possible, look for a Walmart brand of nail polish called HOOF. It makes the nails stronger. I was only able to find one bottle there and then for whatever reason they've been out of it since. Even the new Walmart doesn't carry it, but they do have it online. I discovered it right here on this forum, and loved it. Used it 2 or 3 times then my cat got hold of it and now I can't find it.
