Hi! I'm using minoxidil 5 percent. It's mixed at the pharmacy as we can't buy 5 percent over the counter in Canada. I use the liquid but just ordered the foam from the US online in the 5 percent to save some money. It is About a third of the price per bottle.! I want to try the foam as well. I also am on spiro. Not quite a month on it. I have AGA... Likely exacerbated by heavy stress and medication. I did not experience shedding at all.
