What can I do to prevent hair loss?

Even though it is a natural phenomenon that occurs with aging, I am still concerned about hair loss. I want to delay it if possible and prevent it as much as I can. Currently, I am using anti-hair loss shampoo and trying to consume a lot of black beans, black sesame seeds, and other similar foods. However, it seems like these efforts are not very effective, and I feel anxious, so I want to try other preventive methods if there are any. I prefer methods I can do personally rather than going to a hospital or clinic. I have no intention of visiting a hospital.
