Sorry, what I said was a bit ambiguous. The spironolactone is the topical. The dutasteride I munch. I did experiment with a bit of topical dutasteride, but I gave that up because I suspected it was a bit of a waste. I think the uptake rate of chemicals from the skin has the potential to be very low, and I'm not precisely sure what Dutasteride molecules look like, but I'd wager that they're pretty big = less absorption.
