Lots of Propecia questions this week…
I am 21 and notice that my hairline is going. Should I start taking Propecia?
There are many important elements to your question and like all good questions, the answer may be more complex than you were expecting. There are many reasons for the hair line to move, the most common reason is the transition from having a youthful hairline to acquiring a mature hairline. This frontal change in the hairline occurs in 95% of young men and it is not reflective of the balding process. I can not tell you if Propecia will stop or slow this process down, but I suspect that it might considering that this is probably a DHT induced manifestation.
With regard to early genetic balding, I would get a good doctor to examine your hair looking for miniaturization of the hair shafts. The finding of miniaturization is an absolute sign of genetic hair loss, If you have it, Propecia is recommended to be started at the earliest appearance of genetic hair loss in the post pubescent male. Since genetic hair loss is a progressive process, the earlier you get a good diagnosis, and begin Propecia, the better your chance is to keep your hair for a longer period of time.
