myhairr..... There is no drug other than Propecia/Avodart/Proscar for slowing down hair loss in the top/crown area of the hair, but that's a good place to start. Unfortunately, there's nothing proven to re-grow or even stop hair loss in the front--yet. At only 19 years old you will most certainly be encouraged to start on one of the three meds that I mentioned and of course Rogaine can be applied to the head as a topical foam together, again, with one of the three. The path that is the best, generally speaking, is to start that regime and see how your loss slows down, hopefully, then because of your young age wait to see even further how and if your loss is progressing and eventually get a consult with a doctor who will map out a long-term plan for the best use of your finite donor hair. There's way more to learn about so when others chime in you'll get their advice and directions. Good luck!!
