Why Might Propecia Not Work for Some Men?

Dear Dr. Rassman, I’m a 22 year old male and have been on Propecia for a little over a month now. I’ve heard you say that it takes 8-12 months to see if the drug is effective and I’m just curious, why would the drug NOT work for all men? We all have DHT and this drug has the ability to eliminate or reduce the amounts of it in our body. Do some men have larger amounts of DHT than others? Thank you for your time and thank you for your blog, I have to say it is the most helpful website on the Internet. Take care!

It is my belief that Propecia works in 100% of men your age. What I mean by “works” is that it will slow, stop, or reverse hair loss. As you have been taking it for only a month, it is far too early to judge just what your benefit is. Did you get your hair mapped out for miniaturization? Such mapping will give you a measurement by which to judge any benefit. The amount of DHT your body makes is a direct relationship to the testosterone made, as it is a breakdown product of the testosterone. Men with lower testosterone might have lower DHT levels.
