How many years of MPB does one have to go through before considering an HT considering the following facts: I started to notice hair loss at age 17 and now am 20. I have been using Propecia for 2 years now and it has maintained most of my hair (temples and crown have thinned out a bit since then but nothing cosmetically significant). My father and my grandfather are both NW6 and my uncles are mostly NW5-6. I have been losing my hair for almost 4 years now, how much longer do I have to wait before I go for an HT?
It is not about how long you should wait, but rather it’s more about building a Master Plan with your doctor to address this concern. A good doctor will always work off a Master Plan that you and the physician will create. Your questions will then be answered, because you will have a customized plan to meet your exact problem and address the rate of your hair loss. As you were already prescribed Propecia, stick with it and hope the results continue to be positive.
I don’t know enough about your current hair loss, but hair transplant surgery at 20 years old is not usually recommended. There isn’t a real minimum age for having this procedure, but we generally don’t do these in men under 24 years old, because the hair loss pattern is not clearly defined.
