(Concern) Early symptoms of hair loss??

I used to have a lot of hair, but due to various stresses, my hair started falling out significantly at some point.ㅠ

My hair falls out a lot when I wash it, and seeing hair scattered on the floor makes me so heartbroken ㅠ

I've tried black beans, of course, and also used hair loss shampoo. These days, I've been consistently using beer enzyme? The granule form of it for a few months.

I'm eating, and I think the effects are a bit subtle, but it's still not enough ㅠㅠ I saw someone on the street with long hair.

There are so many hairs that when I see the waves and shiny strands, I really envy them. Is a hospital the answer for hair loss? ㅠㅠ
