I saw a dermatologist about finasteride/duta. He told me he flat-out refuses to prescribe oral finasteride, and said he'll likely put me on topical finasteride. Is there some amount of topical I could put on my scalp that would do me as well as 1mg oral? I only want to put it on once a day in the evening so that I can shower in the morning and avoid bad hair – I switched to oral minoxidil after a couple of weeks for the same reason.
