Concern about baldness on the crown of the head ㅠ ㅠ

I haven't had a lot of hair since I was young, but it wasn't this much ㅠㅠ

As I get older, is it inevitable that my hair also gradually becomes thinner?

I'm going to become a bald eagle at this rate ㅠ

I'm getting more and more bald on the crown of my head, and it's stressing me out.

Male hair loss is stressful, but women experiencing hair loss... wow... suddenly feeling very depressed...

Will hair loss medication or treatment definitely be effective?

How long should I receive treatment? About 6 months? 1 year?

It's not a very old age, but it's not a young age either.

If the results are good, I want to consider long-term treatment.
