Which of the following conditions may indicate a need for specialized treatment by a healthcare professional?

Severe hangnails can lead to potentially serious complications if not addressed properly. Hangnails occur when the skin around the nail becomes torn or detached, and if they are severe, they can cause pain, inflammation, and even infection. Such conditions may require professional treatment to ensure that any underlying issues are properly managed, particularly to avoid worsening the situation and ensuring that the skin heals correctly.

In contrast, the other conditions listed either do not warrant professional intervention or can typically be handled with basic home care or standard nail care practices. Healthy nails do not require any treatment, minor nail breakage can often be managed with simple nail care techniques, and chipped nail polish can be easily repaired during a regular manicure or at home. Therefore, severe hangnails stand out as a condition that could necessitate a visit to a healthcare professional to prevent complications.
