Has anyone been to a hair loss clinic?

Lately, I wonder if it's hair loss because even when I wash my hair, and on the floor, there are a lot of hair strands.

I regularly sweep my hair and remove the fallen strands, but when I vacuum, more come out again ㅠ

My younger brother also thinks he has hair loss, and he went to the hospital. He's currently undergoing treatment and was told it would cost 3 million won for six months.

They said they would think about it because it was burdensome, but they haven't even been to the hospital or have any knowledge about it.

Is 3 million won for six months expensive? Or is it reasonable?
