hyperhidrosis
"My sweating is confined to my head and face. I must be the only one because the posts I've read is under arms, feet and hands. So I went to my dermatologist. I wanted Hypercare but he opted for the slightly weaker medication Xerac to start. It really stung my forehead the first  time, I left it on for three hours and had to wipe it off my face. Scalp was okay. Next day head sweat cut by 75 % I'd say. So last night it did not sting at all on my face. Left it on all night. Will see how I do today."
