Dermatitis is an umbrella term that covers a range of inflammatory skin conditions, including eczema, psoriasis, contact dermatitis, and seborrheic dermatitis. It is important to note that these conditions can and do vary in severity from person to person.
The short answer is that dermatitis can potentially go away in some cases, depending on the underlying cause. For many people, dermatitis is a chronic condition that can wax and wane over time or may even remain present for years. If the cause of the dermatitis is identified and treated, it can often be brought under control and the symptoms can improve or even disappear. For example, if contact dermatitis is caused by an allergen, then removing the allergen from the person's environment can often resolve the dermatitis.
However, the process of treating dermatitis can be long and complex, and the condition may not go away completely. Depending on the type and severity of the dermatitis, it may be necessary to use a combination of topical medications, lifestyle changes, and other strategies to keep the condition under control.
In conclusion, dermatitis can sometimes go away, but it is not always easy to achieve this. Treatment for dermatitis is often a multi-pronged approach and may take time to be effective.
