I'm worried about hair loss.

At some point, my hair started to thin, and it seems like I'm losing more hair than before. I haven't consulted or received treatment at a hospital for hair loss yet, but if my hair continues to thin and fall out like this, I think I should visit a hospital for a consultation. These days, there are many shampoos, supplements, and hair products that are good for hair loss, but I'm not sure if they'll be effective.
