(Concern) I'm worried about hair loss on the crown of my head.

Hello, I want to write about my recent worries in this event. As I get older, hair loss has become a major source of stress. Actually, I don't have a lot of hair to begin with, but I feel like the crown area is gradually sinking and becoming empty. I have tried switching to anti-hair loss shampoo and am also taking medications like Panthenol. I'm honestly doubtful whether these are effective or not. Or would it be better to go to the hospital and take prescribed medication consistently? Looking in the mirror really causes me stress.
