Is It Possible To Stop My Maturing Hairline?

I am 18 years old and I am seeing my hairline rising. Can we stop this change with Propecia?

The mature hairline is present in about 90%+ of men as they mature. I don’t have any experience with stopping the hair loss in the very front of the hairline that is typical of children. At 18, without seeing you, I don’t know where you are in the process; however, I don’t believe that the zone between the leading edge of your juvenile hairline and the place where a mature hairline will end up (see reference above) is mediated by the balding gene as this is not balding in the typical sense of the word. These hairs undergo Apoptosis (cell death) and that is programmed into your genetics. I have had young men on Propecia in the past, and I do not remember any of them where the transition from juvenile hairline to mature hairline was stopped by this drug.
