I'm worried about hair loss with continuously thinning hair.

Hello, I am sharing my concerns through this event. Recently, I have noticed that my hair has become very thin and is falling out when I look in the mirror. This has become a significant source of stress for me. I have been using medications like Panthenol, black bean soy milk, and anti-hair loss shampoos, but I am not sure if they are effective. Should I just go to the hospital and get prescribed medication? Or is hair transplantation a better option? I also want to know if the prescribed medications have any side effects. I am very stressed about hair loss.
