I would advise the manicure staff to familiarize themselves with Shellac removal procedure in order not to deeply damage your nails savagely scraping away the surface layers of the natural nail plate. First of all, instead of using metal scarper you should use orange stick or at least plastic scraper. But if you do use metal scraper you should be careful with it and place it appropriately relatively to the nail surface. And no, my nails had not been not broken before that cruel procedure-the nail plate was solid and without any cracks and splits. Now 3 of my nails have deep cracks, those nails from which shellac was removed by metal scraper placed inccorrectly relatively to the nail plate.
Shall I ever have my nails done in this salon that positions itself as a high class salon with highly skilled professionals?-Definitely not!
I can't say anything about your other treatments, but, you know, I do not particularly feel like trying them on myself after that.
