My hands were soaked in a warm acetone mix to get off my previous gel polish instead of just my nail being covered/the foil method. And then scarped off a lot, my nails were hurting a little. Which surely can't be good for the hand.
The beautician was not very friendly and was just on the phone for a lot of it. The venue also doesn't feel very professional and the procedure felt rushed.
Had shellac done and it last for weeks. Best place to have this done. I defiantly recommed. It lasts for longer than 2 weeks and I do a lot of work with my hands.
