Does anyone know if these supplements work if your hair loss is medication-induced?

I have RA, and the medication that actually works for me (we've tried quite a few) causes some crappy side effects, but the worst to me is the hair loss. It is visibly thinning, and even though others say they can't see a difference, I can. I can see it, and I can feel it. If some supplements would work, I'd be a happier girl.
3a on top and sides, 3b underneath in the back, and 2-something in front. What a mess....
