Hyperhidrosis
"TO ANYONE FOR WHOM THIS HAS NOT WORKED WELL:  this didn&#039;t work for me at all...until I trimmed my armpit hair significantly. Try it! I did not shave it as I knew this would cause serious irritation. I just used hair trimming shears and trimmed it down to basically nothing. Now this has gone from doing nothing to working almost perfectly.  Before you give up hope (and I know how hopeless this condition makes one feel) give this a shot; I assume it works because the medicine is absorbed better."
