Would my beard hair be considered terminal? Have been using Minoxidil to enhance facial hair. (photos)

I used minoxidil to enhance facial hair and I’ve heard many different outcomes regarding stopping the use of minoxidil. One outcome is that you’d have to wait til hair becomes terminal to cease use and the other is no matter how long you use it’ll fall regardless when stopped. What outcome is true ? Also is minoxidil safe for prolonged use? ex; 2-3 years
