In addition to their aesthetic function, our nails are a true indicator of our overall health. Sometimes, without warning, they change their appearance and display intriguing vertical or horizontal grooves. Should we be concerned? Is this a simple sign of fatigue or a symptom of a deeper imbalance? Follow the guide!
Vertical stripes, horizontal stripes: What do they mean?
Vertical ridges —running from the base of the nail to the tip—are the most common . The good news is that they’re often completely normal, especially with age . Like wrinkles on the skin, they develop when cell turnover slows. So, it’s more a matter of maturity than pathology.
However, if these grooves become more pronounced, if the nails become brittle or change color, this could indicate a mild deficiency (in iron, zinc, or vitamin B) or dehydration of the nail . Nothing serious, but it deserves a little nutritional boost .
Horizontal lines—so-called Beau’s lines—should be closely observed . They usually indicate a temporary slowdown in nail growth, often related to a significant event: a high fever, significant stress, or a recovery period. In short, they mark a “standstill” experienced by the body .
