I started to post this in the Ladies Forum but then I thought this might happen to guys too on their necks. In the hottest part of the year I often get a nasty heat rash under my arms when I shave there. It's not a red razor burn kind of rash. It's lots of tiny little white bumps that pop up right after I shave and then the area gets really tender and red. The hotter the day the worse the rash. Going sleeveless helps some but then people can see it and that's embarrassing because it looks awful. If I use baby powder or corn starch after the bumps come up that just makes it worse like I'm dusting the area with sand. Is there anything I can do pre- or post-shave that will prevent the bumps from coming up at all?
