Concerns about taking hair loss medication

I'm not sure if I can take hair loss improvement products.

​

I'm thinking about taking medication because of hair loss these days.

I'm worried because I plan to keep eating it.

Is it okay to take hair loss medication?

I wonder if there are any side effects.

I also want to stop hair loss.

I'm worried because I don't want to miss out on the effects.

Anyone with similar experience, please give me some advice.
