(Concern) I've been losing a lot of hair lately, and I'm worried.

As I get older, my hair loss has become more severe. Just a few years ago, I had thick hair. But recently, I’ve been losing a lot of hair to the point that it’s noticeable. Hair loss with age is inevitable, but I still worry about it a lot. The only thing I’ve been doing lately to prevent hair loss is using anti-hair loss shampoo. Is there any other good method to prevent hair loss? If it’s unavoidable, I might have to visit a hospital, but I want to try anything that might help if there’s a good method.
