2-4 weeks: Contact dermatitis won't clear up until the allergic trigger is removed. For example, if the cause if nickel allergy you may have to change jewelry and the front closure on your jeans. Untreated the rash resolves in 2-4 weeks. Oral Prednisone will usually clear the rash in 5-7 days.

The time it takes contact dermatitis to clear depends on the severity. Wihtout treatment 2 to 4 weeks is not unusual. Topical steroids can also be very effective treatment for this condition with minimal side effects.

Depends: Contact dermatitis usually takes several days to improve, assuming you are no longer being exposed to the trigger. If you continue to be exposed to the cause, the rash can be ongoing.

One month: It can last 2-4 weeks or longer after the cause of the rash is removed and avoided. If the cause of the contact dermatitis is not removed then the reaction can persist as long as you're in contact with the offending agent.
