The causes of nail peeling disease are complicated, mostly due to trauma, external chemical agents or fungal infections, etc. Patients can be treated by topical medication, stopping the application of chemical agents, oral medication, and so on. 1. Topical medication: If the disease is caused by trauma, the patient can cut off the peeled nails, and the new nails will grow against the flesh to achieve the effect of treatment. 2. Stop applying chemical agents: If it is caused by topical application of chemical agents such as nail polish, nail hardener, etc., just stop applying the relevant chemical agents immediately, and the nails will gradually return to normal. 3. Oral medication: If nail peeling is caused by fungal infection, anti-fungal treatment should be actively carried out, and patients can take oral terbinafine, itraconazole and other drugs for treatment. Patients who have nail peeling disease should go to the dermatology department in time for examination and treatment under the guidance of the doctor, to avoid unauthorized use of drugs on the body to cause serious harm.
