Severe hair loss started in my twenties, what should I do?

Hair loss has become more and more serious in the past year, and my hair is getting thinner and thinner. I’m so afraid of becoming bald, ah~
I wonder if anyone has the same situation as me?
Hair falls out everywhere in the toilet every day. When I look in the mirror and see myself, I feel anxious. I have also used many anti-hair loss shampoos on my hair, and I have also seen doctors using anti-hair loss lotions and hair growth lotions, but none of them worked.
What should I do? Is there any recommended solution for hair loss or hair growth?
