Are black beans good for hair loss?

There are always roasted black beans on my table.

It's not just because of hair loss, but also because I like it.

I don't take it because my hair is too thin; I just take it because I like it, but I'm in my mid-40s and I still don't have any gray hair.

I'm not sure if it's the effect of the black beans, though.

Will this be effective for hair loss? I wonder.

I eat it thinking it's better than not eating at all.
