Here's a proven way to grow long, strong fingernails, the only hitch is it takes a few months to show, and you'll need to keep it up. Here it is. Everyday eat a small bowl of jello, yes as in J-E-L-L-O. Can't repeat the scientific why it works, except that gelatin and fingernails have similar properties, it's miracle grow for nails and hair. The hard part is to have some on hand everyday. There are pure gelatin capsules too but they can be hard to find, not impossible, there's only one pharmacy in my area, but that's all it takes. And this absolutely works.
