Hello Doctor ,
I have been taking propecia for 6 years with a great success , but i am close to 30 years now , and i was wondering if i could stop it now. Don’t you think that with our Testo levels decreasing over age (about 2% per year after 30) , the DHT levels will decrease too, so that we could stop the propecia by getting older ?
Good thought, but taking Propecia is not directly related to testosterone levels. Propecia affects DHT levels, and even DHT levels do not tell the full story. For example, even with high testosterone levels, you can have NO hair loss. Conversely even with low testosterone levels you can have massive hair loss.
The root of the problem (pardon the pun) for hair loss in men is genetic, not DHT. As such, there is no definitive cure. But if Propecia is working well for you to this point and you have no problems, why stop it? In reality, you should never stop taking it, as long as you wish to retain your hair.
