I have a client that has been coming to me every two weeks for shellac with no problems until a couple of weeks ago. She came back to me her shellac had started pealing off whole and had discoloured her nails tge same colour as shellac. I reapplied and she came back to me weeks later saying the same thing had happened again so she went somewhere else who uses shellac because she thought it was me!! But the same thing happened there. She also informed me she's always used opi bail varnishes before starting to have shellac and it happened with that after a while even with using thier base coat. Any body knows what it is? I have tried different colours on her and it's happening with them all I have done nothing different in my technique and she's the only person this has ever happened to x
