Pediatric gray nails should be treated in time, mainly eliminated by medication, including local and systemic treatment, and using surgery when necessary. 1. Medication: local medication includes amorolfine application, cyclopiazone application, etc., which can effectively inhibit fungus and is suitable for white superficial and distal lateral subnail type damage. Anti-fungal drugs such as terbinafine and itraconazole can also be taken orally, and the efficacy can be improved by combining with topical drugs. Specific medication should be used under the guidance of a doctor. 2. Surgical treatment: when the effect of drug treatment is not good, surgical treatment can be used, including nail extraction or nail removal. When children have gray nails, they should consult the doctor in time, treat under the doctor’s guidance, pay attention to personal hygiene, and pay attention to the disinfection of shoes to avoid the transmission of gray nails.
