various drug (finasteride, spirinolactone and recently dutasteride) from reddit

As a clinical scientist, I am not clear about your results. I would suspect that if there is a change and you have been on finasteride for a long time until you switch to dutasteride 1 month ago, that the benefits you see are related mostly to the finasteride and not either the dutasteride or the spirinolactone. This is important information for the readers, listening to an expert address your results. I wish you had comparable pictures because the longer hair makes a huge difference in the appearance and although it does look like there is hair where there was none before, the results may not be as dramatic as you may appear.
