Propecia Worked Great for 10 Months, Then It Got Worse Than Before

Hi doc. I am a 22 year old male and I have been on propecia now for about 13 months. It has been working very well for me, and I was even getting some regrowth at my temples and along my hair line. however, around the tenth month my hair started to get worse, and I started to loose more hair and my hair looks as though it is miniaturizing especially along the hairline and my temples. This has been occurring for the past 3 months and my hair does not seem to be improving at all. Is it possible that propecia is causing my hair follicles to become more sensitive to DHT or that my body has up regulated androgen receptors in the hair follicles to make up for the low amount of circulating DHT? I just wanted to know what I should do? Thanks.

It would be highly unlikely that Propecia would be causing your hair loss. The most likely explanation is that your genes are causing your balding process to continue, and Propecia can only do so much to arrest the process. It is possible that the hair loss process has itself, accelerated.

Since you are using Propecia, you must have a prescribing doctor. You should ask him/her to do a miniaturization study of your scalp to get some metrics knowing at least from this point forward, where your miniaturized hairs are and to what degree they are miniaturized.
