I am concerned about hair loss and hair thickness.

As I get older, my hair is getting thinner, and I find that I've lost a lot of hair when I wake up in the morning.

So I'm using hair loss shampoo, but it doesn't seem to be having much effect. I suspect I'm not the only one struggling with this. Have any of you used this product and seen results, or do you have any reviews? I'm worried it might get worse over time.
