For girls I can see one desire driving many of them OTD. It is the desire to always be able to grow their hair long and not have to shave it every month like a Nazir and Metzorah (for Nazir / Metzorah – a one shot shaving).
Perhaps I am in error, and no woman is ever forced to shave her head to be part of a community???
For those who can not fit in one community, are all attempts made to find them a “home” in another shomer Torah and Mitzvos community???
