Hi Dr Rassman, I thought I recently heard you say on this site that minoxodil stays effective for 22 hours, did I hear you right? Because my thoughts are that I would like to cut down my use of minoxodil to once a day if it would have the same effect and save $ or did I misunderstand what you may have been saying? Thank you. Great blog.
Minoxidil is a twice daily treatment for best results. You might get benefit once a day, but why take it once if twice a day is better (and the recommended dosage). It is not a very expensive medication, so go for it the right way.
