In the vast majority of cases, they are nothing to worry about. However, they may become more noticeable during periods of fatigue, stress, or when the nails lack hydration. A well-nourished nail is usually smoother.
Horizontal Ridges: When the Nail Hits Pause
Less common, horizontal ridges tend to attract more attention. They usually correspond to a temporary slowdown in nail growth. This can occur after a period of significant stress, a short illness, or a physically demanding time for the body.
The nail eventually resumes its normal growth, and the ridge gradually moves toward the tip of the nail. If this happens only occasionally, there is usually no reason for concern, though it is still wise to keep an eye on it.
Diet and Nails: A Connection Often Overlooked
Ridged nails can also reflect a slightly unbalanced diet. When the body lacks certain essential nutrients, nails may become duller, more fragile, or more marked.
A varied diet rich in vegetables, fruits, proteins, and healthy fats can help improve nail quality. Drinking enough water also plays an important role: dehydrated nails tend to show marks more easily.
