Dr Peter H. Proctor, PhD MD answered: "The amount varies , but is typically about 2%. For people who have not been on minoxidil previously, it lossk as though it makes no difference whether we add minoxiidl to the formulation or not. Most likely, htis is because something in the formulat substitutes for it. I leave it in for two reasons: 1) I get tired of explaining why it is not present and 2) In theory, someone who has been on minoxidil previously may be somewhat dependent upon it. If somoen wishes to use our formulation along with minoxidl, say substitutiong it for one of the daily applications, this is fine.
