Are there any supplements that help prevent hair loss?

It seems that having thick hair becomes very important as you get older.

It has decreased a lot even now, so I'm a bit worried, but

Still, I am trying to prevent it in my daily life.

Could I get help with nutritional supplements?

I've tried beer yeast before.

I don't know if I chose the wrong medicine, but the scent is so strange.

I ate it a few times and then stopped.

I heard that biotin is good, so I'm thinking of taking it.

What nutritional supplements would be helpful for hair loss in the long term?
