I've done this lady's shellac a few times who is known around this area for complaining constantly just to get her money back all the time!!! She's always been fine up until the last 6 weeks or so!! Now she has started to complain her shellac is sliding off her nails whole I have re done them a couple of times as a good will gesture but gave explained to her its never happened to me before. Now the last 2 times she said they slid off the next day so I told her that this time she needs to bring the shellac in for me 2 c this is what she brought back. Does anybody know y this is happening I've never had this before she also said b4 the slide off they get a big bubble in the middle?? x
