I have been using shellac and gelish for a little while now. Normally no major problems but... I had a client come in today where on one of her thumbs the shellac had literally lifted. Not just a little chip, proper lifted flap. No nail adhered to the lift, so no peeling nail edge. She is a typist, no medical conditions or allergies. I removed the shellac and we just put on some clear polish as she is going out of town. She told me that normal polish only lasts 3 days max. I dehydrated her nails with scrubfresh before putting on the polish and noticed that they never went properly white and were really shiney again within seconds. Any idea what I could do?
