One Side of My Hairline Regrew from Propecia, So Will The Other Side Regrow Too?

Dr. Rassman, I have been on propecia for nearly a year and half. I started to take the drug at age 27 when I noticed that my hairline receded to a norwood 2.5 pattern. I have noticed that on the right side on my hairline near the temples in addition to the frontal region above the forehead there has been significant regrowth in terms of length and also thickness. However the left side has remained stagnant for the most part. In your practice have you seen this often in young men and what may I expect in the coming months or year?

I as well thought I have suffered from from side effects due to the drug. I had some erection issues and also some gynocomastia develop. A blood test reveal that I had lower testosterone levels and started a strength training and weight loss program and both of the side effects went away while staying on the drug. Many of the users who suspect side effects need to check other health issues.

Thank you so much for taking the time to answer my question.

We see hair loss that is not symmetrical, so I would not be surprised that one side reacted differently to Propecia than the other side; however, you are the first person to have reported this to me. I would go back to your prescribing doctor to have measurements done (assuming you had measurements taken before starting the drug, you can have comparisons made).

With the side effects that you reported, most people would just assume it was Propecia and not even consider any other possibility. It just goes to show that there are other possible reasons for effects that people see, and deciding on your own about the causes of the issues without a medical exam may not be in your best interest.
