Spironolactone
"I've been on this drug for about 2 years and I really like it! Results vary for different people, but for me it's made the hair on my body grow in finer, lighter, and *much* slower. It's not a miracle pill for me (I still have hirsutism), but it's made me 1000x more comfortable in my body. I never had hirsutism on my face, so I don't have any comments about that... In any case, this drug takes a looong time to kick in (6  months for me), but I definitely recommend it!"
