Is hair loss treated by dermatology?

Is hair loss treated at the dermatology clinic?

I think it would be best to take medication, but I'm not sure which hospital I should visit;;

Mom heard somewhere to go to the urology department;;

There is a men's prostate medication that is good for hair loss~

If you go and talk, you can get medication to prevent hair loss. Does anyone know about this?

Can I just say I came to urology because of hair loss?ㅠ
