Wow I started to lose my hair at 15 aswell. You are too young to take finasteride or any hormone altering drug so if I were you I would start dermarolling because there are no side effects. look it up we have multiple threads on this site about it.
Damn lil dude, you skinny as f*** too eh. TIme to say bye to the hair and glasses, get some contacts, shoot up some steroids and get jacked as f*** lol. Actually youre young AF so your hormones are already shooting through the roof. Just eat like a beast, take sh*t tons of creatine, shave your head and go HAM in the gym. Seriously, if your that bad at that age just focus on being a bald stud.
