Reductase inhibitors finasteride and dutasteride are considered hormonal treatments. Ketoconazole has some estrogen aspects. Minoxidil has traditionally been considered non-hormonal and viewed as a vasodilator. There is also some evidence of it having a means of providing palliative relief due to hormonal influences but I wouldn't worry about it in that sense, and really not Keto either. Bottom line? Nobody feminizes on Keto or Minoxidil; dutasteride? Eh maybe depending upon one's point of view. I have never noticed feminization from reductase inhibitors nor do most as they raise T.
