Hi Jen
I too experienced alot of nails coming off when I first started with gel, at the time I was using a 1 phase system.
Since changing over to a 3 phase system with a thick viscosity builder gel my problems have dissappeared.
As the geek points out though it is prep that is the key with any system.
The clients I have now wearing the 3 phase gel are delighted with the fact that they have now grown off the tips and are into a natural nail overlay, seems to give them more time between infills, great for them, not so great for me, but they keep coming back and are happy.
I think you will also find with gel if you investigate, your client might be a picker, once they spot a tiny little defect they will not leave it alone until the whole lot is off. You must have heard it a million times - it just fell off -
Good luck and keep gelling
