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 behavioral disorder that may not seem serious at first glance. However, it can lead to significant damage to the nails and surrounding skin, resulting in potential infections or other complications that require medical attention. Nail biting can expose the nail beds to bacteria and other pathogens, and chronic cases may lead to deformities or scarring of the fingers.

Given the potential for underlying health issues, such as anxiety or stress-related disorders, along with the risk of infections, it is important for a nail specialist to recognize when a condition is beyond their scope of practice. Referring a client with onychophagy to a physician allows for a thorough evaluation and appropriate treatment, ensuring the client receives the best care for both their physical and mental health.

In contrast, onychorrhexis (brittle nails), onychauxis (thickened nails), and onychoptosis (nail shedding) are typically conditions that, while they may require attention or treatment, can be managed by a nail technician within the safe practice protocols, unless they present with severe symptoms that warrant medical intervention.
