When you shower, you should be certain that the affected area
is fully dry prior to putting on
clothing. You should pat rather than rub the area dry, so as not to make itching worse. You can even use a fan, or a blow dryer on a cool setting to dry the area first prior to getting dressed.
If you get frequent outbreaks, you can use an antifungal cream or powder, or even corn starch or baby powder, once a day, to get rid of jock itch more permanently.
