I read somewhere that propecia doesnt prevent baldness it just slows down the process.I am using propecia since i was 19, so should i expect to get bald sooner or later one day even though i continue to use propecia? If yes,on an average at what age will get bald?

Everyone is different and reacts differently to medication. Some people have a strong and aggressive hair loss pattern and Propecia will slow it down, but not by much. Other people have a not-so-strong tendency to bald and it may slow it down for years and years. Others will reverse the balding process. I have a number of patients who took it for crown balding when the drug was first released and the hair loss completely reversed and has stayed normal since 1998 (no evident balding to the naked eye, although it can be seen with some miniaturized hair when looked at under high magnification).
