Treating onychotillomania can be challenging as no evidence-based treatment options are available
Onychotillomania is a chronic psychodermatological disorder characterized by a repetitive, compulsive urge to pick nails that causes temporary or permanent trauma to the nail unit. Physical barrier methods, cognitive behavioural therapy and pharmacotherapy with psychotropic medications have shown some benefits in case reports, but no large clinical trials have been conducted to assess their efficacy. As a result, evidence-based treatment options for the management of onychotillomania are currently lacking.
