theres nothing you can do mate, its purely genetic, no matter how much you want to hear there is a cure its not going to happen, mpb starts around the age you have stated, classic sign is receding hairline followed by balding in the crown, yours sounds quite aggressive, and if especially the proscar hasn't helped after 2 years i personally would discontinue it, your still young and risk permanent side effects, do NOT get a hair transplant at your age, shave you freaking head and get on with your life
