Now in my mid 70s, I feel extremely fortunate to have retained good hearing when I  consider that almost to a person my male friends are wearing, or should be wearing hearing aids.  Not being able to appreciate a good sound system is one thing, not being able to hear people speaking is causing more and more of my friends to self-isolate due to embarrassment over their communication difficulties. While I'd love to be able to regrow my hair, I'd rather see advances in restoring hearing.  Both will come along,  The sooner the better for hearing.

Homeopathy really works.

No.  It really, really doesn't work, beyond a placebo effect.  It has no scientifically coherent theory, and no scientific evidence.   It's just the usual anecdotal evidence that keeps all alternative medicine afloat.It has no more solid empirical evidence than consuming ground rhinoceros horns as a fix for erectile function.
