I have been using SNS nails for about 11 months now. Love the product, however the last month or so, I have had clients come back they say the whole nail has lifted and come off whole? I prep the nail.....push the cutical back, lightly buff the nail, clean with acetone to dehydrate the nail, ea bond. I have even started to use a base dip (natural set) to strengthen. I absolutely know this should not be happening but have no idea why? I did my sisters yesterday. She looks after then, text today and saidnthe while nail has come off. Please help
