Ugh, I saw such a horrible picture Nails Uppsala Facebook that shows why you should not go to rogue salons just because they are cheap.
This is not her customer, the picture is not from Sweden, but the principle applies to everything that has to do with cheap salons. Sometimes you earn more by paying a few hundred bucks extra.
This girl did gel polish at a cheap salon that used some kind of fake polish, so her nail melted under the LED lamp and destroyed so much that it will probably never grow again. Heeeemskt! And think what harm it must have done !!
I do not know how common it is with just rogue nail salons in Sweden, but eyelash extensions, makeup tattoos and such beauty-related salons, there are a lot of cheap and rogue even in Sweden and you really have to be careful.
An ugly make-up can be washed off and a failed brow pick grows out, but when it comes to more sensitive things, promise me to check out the salons properly before, and do no "spontaneous" when you are abroad, especially if the price sounds too good to be true!
