This isn't entirely true...
I have found this has happened to me a few times recently with the new gellux easy off base coat. It happened on clients when I first switched over but has stopped now once I got used to it, but it has been happening on my own nails. I'm rubbish at doing my own nails, I struggle to cap them properly and the coats are a little thick. And today a nail literally fell off, I saw it happen. And it's not the first time.
So sorry to disagree Geeg but yes it could well have done.
So in reply to the post I would check a few of the usual things, like is your lamp working properly, has your client started new meds (roaccutane and pregnancy has been known to cause issues) and are you sealing the free edge properly and doing thin enough coats? As these last too issues are what caused my problems although it is using a diff gel xx
