I've been a nail tech for 6 months and I've never had anyone complain about the way I do nails or my process. I have lots of repeat customers and everyone goes away happy. I've had nails last on clients for weeks with no problems. About 2 weeks ago I did a woman's nails and she texted me a week and a half after to say that all of her nails had come off...ALL OF THEM. I've literally never had this happen, ever. She wants to come in and have them redone for free or she wants a refund. I fear this might be my fault because when she got them done she asked how long they should last, I said, off hand, "two weeks or more" because that's normally the minimum with my other clients, and that's only if their nails grow really fast. I'm not sure what to do, any help would be appreciated!!!
