I will not be returning to this salon.
They filed down my nail with an electric machine to remove the Shellack they had applied a month earlier..
Shellack should always be removed with acetone, and most certainly not with an electric drill if one lacks the skill to do it without harming the costumers. I went to see the doctor after a lot of pain and two fingers becoming swollen and was told that shaving the nail like that is dangerous and could cause infections.
