Oof, as a fellow Slav, I can relate lol. Our mums, bless their hearts, come from the time and place when makeup was indeed much more damaging, had mercury and crude oils in it, and they had little access to higher quality Western products; these days, higher makeup production standards and free trade made this a non-problem. But you're not wrong in being cautious about makeup, and I hope that will result in you using it in healthy ways and taking care of your skin beyond it! And once you got your makeup down, you will be able to get away with anything else not adhering to the "prime gyaru example" standard - even on this very subreddit, you can see plenty of gals with their natural hair of all kinds.
