glue dots or similar products along with GPN
Your mileage may vary... there are the one-use dots that Rico sells, which are also simple craft glue dots. You take them off at the end of the day, remove them from the nail, and you can reuse the nail with new dots the next day. Not perfect for GPNs because of the curve at the base of the nail bed, but they work with Ricos and drugstore nails. They'd probably work for larger nail beds.
Then there's the glue dots that come with the drugstore "press on" nails. Much more adhesive. Same applies as above but have lasted me up to 5 or 6 days. Be very, very careful removing these, as if you're too quick it can take off some nail with it. But a decent temporary solution. Remove these slowly with oil or even butter!
Best option for GPNs is nail glue, as sold by Dave or whatever you prefer. I have also used Dave's method for drugstore nails (but leaving space at the cuticle uncovered by the fake). His method really works and will keep nails on for a long time. I've found they'll fall off easily eventually, if I'm just growing out a natural nail.The downside for me is if I use them too often my natural nail is affected somewhat. But the method is very secure if you need a very reliable nail that will stay put for a performance.
