How is hair loss treatment done?

I feel like my hair is gradually thinning more and more.

I can't ignore the hair falling out either ㅜ

It comes off quite well even while wiping, but as it dries...

Losing a little more each time,ㅠㅠ

I'm curious about how hair loss treatment is typically administered.

And when treated, it is less likely to blink or dry out.

Is it falling out?

I'm very curious about the most important costs as well.
