I don't know how to explain exactly how or why they are attracted to the 5AR enzymes so strongly but they seem to have an attraction to those regions where 5AR enzymes are. OR I could just be confused to the expression these drugs have after AR binding, but I don't think that is the case. They really seem to stay active in the skin, this is why these drugs increase sebaceous gland excretion so much... It seems unlikely that their expression would produce that effect if they weren't attracted to 5AR regions..
DHN enhances the "androgenicity" sure.. But it has a much lower AR affinity..
