What nail disorder can be serviced by a nail specialist in the absence of infection or inflammation?

The correct answer is that a nail specialist can service onychophagy in the absence of infection or inflammation. Onychophagy, commonly known as nail biting, does not typically involve an infection or significant inflammation that would prohibit professional nail care. Nail technicians can provide services such as nail shaping, polish application, and advice on how to stop the habit, focusing on the appearance and health of the nails as they grow out.

In contrast, phylogenic granuloma is a growth that often occurs as a response to irritation, trauma, or inflammation, making it a condition that typically requires medical attention rather than treatment by a nail technician. Onychorrhexis, characterized by brittle and split nails, might be addressed by a nail technician but could have underlying causes that may need medical evaluation. Onychauxis refers to thickened nails, which can also indicate underlying conditions; thus, treatment should be approached with caution and may often require a healthcare professional's intervention.
