In fact, you can also consider training in electrolysis in St. Petersburg - this is slightly better than depilation and you will get much more for the money. Here is an example https://elektroepilyatsia.ru/kursy-po-jelektrojepiljacii-v-sankt-peterburge/ - there is both paid and free information about electrolysis courses in St. Petersburg.
Zayka Studio conducts such courses. A small studio, but surprisingly - all the documents are there, in contrast to 99% of the salons working in St. Petersburg. I personally checked it. My wife studied at the "Bunny" so even I know what's what in this area. In Insta or VK look for Studiya_zaika. Cheap, quickly, without "water" and high quality. They give out a certificate, which is confirmed if necessary, help with employment, It was not in vain that I gave my wife money for this.
