People have been using fingernail glue on their nails for many years now with no problems. In most cases, those who have had problems with artificial nails is the result of operator error. If used correctly, your natural nails will be fine. We've been doing this now for over 25 years, and have several hundred guitarists who use artificial nails on a regular basis, including many professional players; Eliot Fisk, Grisha Goryachev, William Kanengiser, and many more, with no problems. Guitarists have been using nail glue (super glue) with all sorts of things, ping pong balls, silk and fiberglass wrap, even toilet paper. It's not perfect, but it's the best glue there is for fingernails. That's why they call it fingernail glue. When you use fingernail glue you should always leave the back of the nail free, and then taper the border where the nails meet. Always have free nail at the back. The nail will always grow out; you will always have new nail. It's very important to keep the nail sealed, which again is very easy to do, but you need to be aware of it. I personally have been using artificial nails for over 30 years now; my natural nails are fine, and many others have the same result. We are aware of the problems that you can encounter using nails and fingernail glue, but we've pretty much found out why, and have solutions to them. So you can have problems if you don't have much experience and you don't do some things you should do. But most people learn how to do it correctly and have great sounding nails for many years. I should also add that there can be a bit of a learning curve when first learning to use artificial nails. So that's why we do what we do. And we're more than happy to help anyone with their nails whether they use ours or others.
And for DaveLeeNC, make sure to build up your natural nail with a bit of nail glue first so that there's no more sensitivity, then apply the nail. Keep it sealed well. And we're here if you need us. Thanks.
