Is it common for women to manage hair loss by consistently taking medication?

Lately, I feel like my hair is thinning, so I'm looking into various things.

I initially thought of products like shampoo or scalp ampoules.
The more I looked into it, the more I found that the treatment method for hair loss can vary depending on the cause.

I was a little surprised to hear that there are cases where women also get a diagnosis at a hospital and manage it with medication.

I'm not even sure if I have hair loss yet, so...
I don't think taking medicine right away is a bad idea, so I'm planning to get tested first.

Have any of you received treatment for female hair loss?
Could you please let me know what explanation you received at the hospital?

I am also curious about what criteria are used to determine the treatment method in the beginning.
