I can't tell you about my experience, because genetically I'm all bald, and I'm almost bald by the age of 35, so I don't worry about it. But as for my wife, it's a sad story. Her mother has very thick hair, and hers is thin and constantly falls out and gets clogged in the bathtub, which I then clean)) And as for vitamins, her experience is that you need to choose vitamins revive hair growth vitamins for women, exactly those that are best for you, that is, by trial and error, otherwise nothing will work.
