Tried spironolactone on the crown, way to messy for me . Same with minoxidil. I'm testing it in the front now because it's easier for me to apply.
If i get ANY kind of success with it I'll do it in the crown too , because it's supposed to be better there.
However I stopped the spironolactone completly because it reeks like rotten car tires (was using the newest batch from dr.lee)
