Is there treatment for hair loss?

There doesn't seem to be a specific treatment for hair loss.

I used to have severe hair loss, but these days I think it's normal.

A person I know has a bald spot on the crown of their head, so I'm asking.

I'm just wondering if anything new has come out lately.

There is still almost nothing besides planting, right?

Are the transplant recipients doing well?

Does it last long?

I heard that Jung Woo-sung, whom I like, also had an M-line transplant in the front, and he still looks fine.
