Thanks everyone for your replies.
1> She had Gel on before the acrylic, applied by a different tech. She did not get on with them at all, she ended up snapping her natural nails. It was Biosculpture.
2> She contacted me and asked specifically for Acrylic extensions which she'd had before and liked but did not want to go back to the original salon.
3> I soaked off the Biosculpture, re-prepped the nail and applied Acrylic. They came off 7 days later and was a clean lift on all nails.
4> I inspected the nails and thoroughly re-prepped then applied a second set of Acrylic and 4 days later they are off again. I have just spoken to her and she says it is the same problem, a clean lift on all nails.
5> I've been doing nails for 18 months, first just friends and family and now working full-time for myself. I'm getting good results with 99% of clients using either Acrylic, GelAcryl or Gel but this one is baffling me.
I'm going to have a word with my training provider, and maybe book a one-to-one troubleshooting session.
Thanks Again
Laura.
