My Doctor Diagnosed Me with MPB Right Away

Hey Doctor Rassman, I have a question regarding early MPB. I’m 19 years old and my hair recently started thinning at the hairline and my temples have very slightly receded. It’s not at a stage where the untrained eye would notice, and my friends who I’ve pointed it out to think I’m crazy, to give you a picture of how early it is right now. But my dermatologist diagnosed it as early stage MPB right away when I asked her about it and she prescribed me propecia. So my question is:

Does thinning/receding at such an early age usually indicate a more serious case of balding? Does it generally mean more aggressive balding as well as a eventual higher NW# pattern? I know it can all be so very random sometimes, but I’m just wondering what the average case comparable to mine usually ends up at, if there is such a thing.

Starting age of your hair loss doesn’t indicate degree of future balding. You could start early and get to your pattern quickly… then stop losing hair. It’s different for each person, obviously.
