Nature is unfair !!!!
Some women have mustaches and other not, that depend of their level of testosterone or their heredity factors.
Moreover some women are “luckiest” than other, blond have more preposition to laser for hair removal and they can have a little mustaches and because of the light colors we don’t see it.
But the real question is why is it considered as unhygienic and ugly?
Because when we think about the idea that women have more long head hair than men but not above their lips… that can be contradictory!
The most obvious reason is that nature (society?) decided that mustache will be a men feature as body hair in general which is I think totally UNFAIR!
This is a women point of view.
Now women or men we are waiting for your reactions on this question…
