otc EFFECTIVE treatment for female hair loss?

i have been losing my hair for ten years and is really ugly. i have a thyroid condition but i am already being treated for it and the hair loss has only gotten worse. i have tried rogaine. its useless. been to dermatologist who biopsied my scalp, diagnosed me with hair loss and gave me an anti-fungal shampoo that did nothing. any ideas for effective hair regrowth?
i am 24 years old, have two kids. hir loss increased ater recent birth but started when i was 14. no one else in m family has it.
