How did I dismiss it? I literally said if he is having side effects he should stop taking it. In fact I had mild sexual side effects myself and I eventually stopped taking finaseride. I have posted that information about myself on this forum many times over the years.
I don't currently take any hair loss meds because I decided I didn't want to continue on meds forever. I tried minoxidil many years ago and had heart palpitations. Then I tried finasteride and was taking that for about 11 years until I noticed I had been losing hair anyway and as I said, with some sexual side effects and that fact that I would rather not stay on it forever, especially if it wasn't keeping my hair anyway, I decide to stop. However both finasteride and minoxidil do work for a lot of people, so I do think people with hair loss should seriously consider trying them or perhaps dutasteride or something else to see if and how well it works for them. If you are just beginning to lose your hair and can keep it or even get most of it back without having surgery then that is the way to go.
