I've been looking into getting into topical AAs in the next few months, and this one seems to be the weakest one and I don't want to adventure more than I have to into topicals. Has anyone here noticed any difference in conjunction with a 5-alpha reductase inhibitor (I know keto is very weak on its own, but if anyone has used ONLY keto the better), or is it just a step further from snake oil status? Thanks!
