My fingers got absolutely butchered by the therapist. She filed down the old shellac, continuously catching my skin with the rough file. As the top coat was very strong the tin foil solution wrap did not work properly so she continued aggressively filing my nails despite me asking to be more careful. 1 hour after I have open wounds on 5 out of 10 fingers, old polish still remaining on my nails unevenly and one sore nail plate that is almost filed to the flesh. Equipment not sterilised properly.
