Is nail lichen planus an incurable disease?

Generally, lichen planus is a common skin condition characterized primarily by flat, polygonal papules appearing on the skin, frequently found on the extensor surfaces of the limbs and sometimes accompanied by itching. For most patients with lichen planus, this disease is not incurable; however, some individuals may develop irreversible damage that is often difficult to reverse. If discomfort occurs, timely medical consultation is recommended. The detailed analysis is as follows:

For the majority of lichen planus patients, the condition is treatable. With comprehensive treatment—including topical medications such as corticosteroid creams, phototherapy, and oral immunomodulatory drugs—most patients can achieve symptom relief or even clinical remission. In addition, maintaining healthy lifestyle habits and avoiding triggering factors can also help control the disease.

The pathogenesis of lichen planus is multifactorial, involving genetic, immune, infectious, metabolic, and other factors. Some patients may experience irreversible complications, such as permanent hair loss due to scalp follicle involvement, or destruction of the nail matrix and permanent nail loss due to nail root involvement. Once such damage occurs, recovery is usually difficult.

In daily life, it is important to maintain a healthy diet, avoid spicy and irritating foods, and engage in regular exercise to enhance overall immunity.
