Hello
So I have been on propecia for 20 years, stopped for 3 years when trying to conceive a child and back on now for about 3 years.
I've have good results and minimal sides.
I took a covid MRNA vaccine (2 doses) the fall of 2021.
Propecia has not seemed to be as effective since taking the vaccine. My hair is not as full as it was.
I have read that propecia eventually loses its effectiveness for some, so it could just a coincidence, but curious to hear if anyone else had a similar experience.
