Alright dude, if you’ve been confirmed of having miniaturization, you have male pattern baldness. It sucks but you are actually lucky compared to a lot of us here.
You caught it incredibly early, and like other people have said, you probably don’t have aggressive male pattern baldness and may keep your hair looking this way for YEARS without treatment.
Take a few photos now of every angle in specific lighting. A few months from now do the same thing, IN THE SAME LIGHTING, that’s extremely important. If you see a change, hop on finasteride and you’ll most likely maintain. Welcome to the club
