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 .
Visible defects on the nails
Do you eat on the go and forget vegetables or iron-rich foods? Your nails can suffer the consequences . A deficiency in nutrients such as iron, zinc, or biotin can weaken the nail matrix. The result: ridges, as well as brittle, soft, or uneven nails.
Consider incorporating foods like lentils, eggs, nuts , and leafy greens into your meals. It’s not a cure-all, but your nails (and hair!) will thank you.
The influence of age (and a bit of genetics)
Yes, over time, our nails become less hydrated and their growth slows down. This isn’t inevitable, but rather a natural process . At the same time, genetics can also play a role : some people are simply born with nails that are more prone to ridges from a young age.
Instead of letting them disappear at all costs, it’s better to learn how to care for them carefully . Because smooth and healthy nails are, above all, a matter of daily attention.
These very trendy (but effective?) natural tips
There’s no shortage of tips on TikTok and Instagram for smoothing your nails. Between the three-sided buffer and castor oil , it’s easy to get lost. While these methods can improve the appearance of your nail surface, they’re no substitute for a healthy lifestyle .
Any advice? Use a buffer once a month, no more often . And opt for natural oils (jojoba, sweet almond) to deeply nourish the nail bed, especially in winter.
When should you consult a professional?
Some ridges may indicate a more serious imbalance . If your appearance suddenly changes, your nails become sore, discolored, or are accompanied by other symptoms (persistent fatigue, unexplained weight loss), medical advice is necessary . Sometimes a simple blood test is enough to resolve any concerns .
Care for your nails every day
Preventing the appearance of ridges doesn’t require complicated rituals. Eat a balanced diet, moisturize your hands and nails regularly (especially after washing), and limit the use of harsh nail polish or acetone-based nail polish removers . And, above all, avoid nail biting : This seemingly harmless action weakens the matrix and promotes ridges.
