I get a haircut because of hair loss.

It seems that my hair loss has been worsening gradually over the past few years.

In the morning, I notice a lot of hair fallen on my pillow or beside my head, especially when I wash my hair, it seems like a lot of hair falls out.

So I can't grow my hair long.

When you have long hair, even a strand or two falling out makes it feel like more hair is coming out.

So, unintentionally, I am maintaining a bob haircut.

I'm curious whether supplements, foods, or shampoos that are good for hair loss are effective.
