Has anyone experienced the effects of hair loss treatments performed at a hospital?

Hello. Lately, I have been noticing a significant amount of hair loss, and the crown of my head feels noticeably thinning, which is a cause for concern. I used to have thick, abundant hair, so I never had to worry. However, seeing my parting line gradually widen—whether due to stress or the onset of genetic factors—has suddenly given me a scare. I have tried changing my shampoo and taking supplements, but it feels like home care alone has its limits. I am wondering if it is time to seek medical help for hair loss treatment. I have seen various programs available, such as follicular injections and laser therapy, and I am very curious to know if the effects of these treatments are actually visible. Has anyone experienced the benefits of hair loss treatment? I would appreciate your advice.
