I am 19 year old male, probably a Norwood 2-2.5 but not yet badly noticeable. If I start propecia now what are the chances that sometime in the future it will lose it’s effectiveness? I want to do somthing about my hair loss but I feel if I start propecia now, by the time I’m in my mid twenties it may lose it’s effectivness. Would it be wise to wait a few years before starting treatment due to my young age?

You need to see a doctor before starting any medication. I sympathize that hair loss can be emotional and stressful, but you will not know what you are treating without a good exam and a miniaturization study. I have an office in Newport Beach (where you indicated you’re from), so I’d suggest that you set up an appointment to see me or come to one of our free open house events and you will learn a great deal about the process and get examined. Assuming that you have the genetic hair loss gene(s), the earlier you start, the better. Propecia does not exactly lose its effectiveness, but what you see is that the progressive nature of hair loss just gets worse with age and even Propecia will eventually not stop the progression.
