if you continue to lose hair having taken propecia for one year, i think it's safe to assume that your hair loss is pretty aggressive. however, you shouldn't dismiss propecia as ineffective, it could still work for you past one year mark.

Usually if you start losing hair when you are 16, and by 19 your hair is approaching an M shaped hairline..you know its aggressive. Aging, stress, fungal infections, overall health, etc can speed up hairloss in some cases.
