What are ridged nails often mistaken for?

Ridged nails are often mistaken for lengthwise grooves due to their visual similarities. Both conditions can present with lines or variations in texture running along the length of the nail. Lengthwise grooves specifically refer to the pronounced lines that can occur as a result of various factors, including genetics, aging, or nail trauma. In contrast, ridged nails may also develop as a result of nutritional deficiencies or systemic health issues and typically show a more subtle unevenness in their surface as compared to distinct grooves. Recognizing this similarity helps in differentiating between various nail conditions, allowing for better assessment and appropriate treatment.
