Taking Propecia For Over 6 Years

I recently made a trip to my doc and he told me that he has known people that have been on propecia since it came out back in 97, and they are still on it and they still have their hair today. Can this be true, people taking it for over 6 years and it still being beneficial? I don’t think my doctor would lie, at least I hope not. What do you think. How come it only works for some patients and not for others? From your experience, those patients that have been on propecia for more than 6 years, have they retained all their hair?

Thank-you for answering my questions

Propecia will continue to work for as long as you take it. There is no guarantee that it will override the progressive nature of hair loss completely, but it will continue to help as long as you take it. If works better on some people than others, that is just the way it is. We are all different and we respond to our balding genetics differently.
