Eggshell nails are characterized as:

Eggshell nails are defined by their very thin and soft structure, making them particularly vulnerable to damage and breakage. This condition can arise due to various factors, such as nutritional deficiencies, overexposure to moisture, or improper nail care practices. Because eggshell nails lack the strength and sturdiness found in healthier nails, they require special attention to maintain their appearance and protect them from further deterioration.

Thick and strong nails, which are often healthy and resilient, differ from the fragile nature of eggshell nails. Similarly, curved and raised nails typically indicate a different condition, and ridged nails are associated with other types of abnormalities, each signifying distinct issues that do not align with the characteristics of eggshell nails. Understanding the specific attributes of eggshell nails is crucial for providing proper care and treatment in a cosmetology context.
