I am curious if there are any hair loss products that you have seen results from.

I have thin hair.
My hair is on the thinner side, so it looks even less.
When viewed from the front, there is a lot of thinning hair in an M-shape near the forehead, so I cover it with bangs.
It seems like I lose a lot of hair even when I wash it normally.
I'm using hair loss shampoo, but I'm not really sure if it's effective.
