Could Propecia Have More Impact as You Age?

Hi Dr.Rassman,

Thank you for this great blog. I have found it to be very honest and informative. My question is regarding Propecia. I hear everyone talk about how it is wearing off or losing its effectiveness, etc. It is possible that Propecia works better for some over time? I have been on the drug for 8 years and i notice from pictures my crown looks better than it did 3-4 years ago. Keep in mind, I never did an actual hair count, but I take pictures in identical settings (same spot, lighting, no flash) every year to keep track of my hair loss.

Even in that small 10 year study, there was a significant portion of people who actually looked better than the 5 year mark. They’re reasoning that MPB is a slow progressive process, reversing it can be a slow process also. Or something along those lines. I’m 38 years old and I know that MPB starts to slow down at this age. I was just also wondering if Propecia would have more impact as the person gets older?

Thank you so much.

We actually do not know the answer. People respond in different ways. Some people remain sensitive to the drug for years and they are the ones that probably get the best results. If it is working, just stay on the plan to keep taking it. When and if it should reduce its effectiveness, certainly go back to your doctor and get his/her advice.
