Allergic reactions may occur suddenly, or develop after months or years of exposure. Contact dermatitis often occurs on the hands.

The rash usually doesn’t start until a day or two later, but can start a soon as hours or as late as a week. Allergic contact dermatitis is not usually caused by things like acid, alkali, solvent, strong soap or detergent.
