Which nail disorder is too serious for a nail specialist to work on and should be referred to a physician?

Onychophagy, commonly known as nail biting, is considered a serious nail disorder due to its potential for significant damage to the nail bed and surrounding tissue. While nail technicians can often address minor nail concerns and provide treatments for aesthetic purposes, conditions like onychophagy involve behavioral issues and may be compounded by underlying medical problems, such as anxiety or stress-related disorders. Because of the risks associated with injury, infection, and further complications, a nail technician should refer clients with onychophagy to a physician for a comprehensive assessment and appropriate treatment options.

In contrast, other disorders like onychorrhexis (brittle nails), onychauxis (thickened nails), and onychoptosis (nail shedding) are generally more manageable within a nail salon setting. These conditions can often be treated or improved through topical applications and proper nail care techniques, making them suitable for a nail specialist to address without the need for medical intervention.
