I use spironolactone 2%, but I use it in conjunction with minoxidil 5 and I have great results. I do have regrowth, but it is nothing dramatic... just a slight rounding off of the edges of my balding temples. However, this plus some spectacular improvement in my existing, but previously thinning hair areas has left me very happy with my results. Can't tell if it's the spironolactone, the minoxidil, or both, but I ain't quitting any of them!
Hair McNair - Hilarious avatar! However, I suspect that Canadian Alberta and all of Illinois outside of metropolitan Chicago would probably go Jesusland too... but the US of Canada would probably claim metropolitan Atlanta, and Miami.
