What condition may indicate an unhealthy nail?

The presence of ridges in the nail plate is often an indication of an unhealthy nail. Ridges can appear as either vertical or horizontal lines and may signal underlying health issues, nutritional deficiencies, or trauma to the nail. Changes in texture, including ridges, suggest that the nail has not grown properly or that its development has been disrupted.

A healthy nail typically exhibits a uniform color, smooth texture, and a strong structure. Therefore, the presence of ridges clearly stands out as a sign that warrants further examination and potential consultation with a professional. Understanding the condition of the nails is critical in determining overall nail health and the necessity for treatment or care.
