When nails lose moisture, they become less flexible and more uneven. Keeping your nails hydrated with hand creams and cuticle oils can help improve their appearance over time.
Skin Conditions and Nail Changes
Certain skin conditions can influence nail growth and texture.
Conditions such as:
- Psoriasis
- Eczema
- Lichen planus
can affect the nail matrix (the area where new nail cells are formed). This may lead to ridges, thickening, or other changes in the nail surface.
If you notice ridges along with discoloration, nail separation, or skin irritation, it may be helpful to consult a healthcare professional.
What About Horizontal Lines?
Horizontal ridges, also called Beau’s lines, are less common but more significant.
They may occur when nail growth is temporarily interrupted due to physical stress or illness. Possible causes include:
- Severe infections
- High fever
- Surgery
- Major stress
- Certain medications
Because nails grow slowly—about 3 millimeters per month—these lines often appear weeks after the event that caused them.
When Should You Be Concerned?
Most nail ridges are harmless, especially vertical ones. However, you should pay attention if you notice:
- Deep horizontal grooves across multiple nails
- Sudden or dramatic changes in nail appearance
- Unusual discoloration
- Severe brittleness or splitting
These signs may indicate an underlying issue that deserves further evaluation.
