If you notice changes in the pigmentation of your nails, it's essential to consult a healthcare professional for an accurate diagnosis.
3. **Nail Fungus:**
- Fungal infections can cause discoloration of the nails, including the appearance of dark lines. Fungal infections may also lead to changes in nail thickness and texture.

- Moles or nevi under the nail can sometimes appear as dark lines. While most are benign, any changes in size, shape, or color should be examined by a healthcare professional.
5. **Nutritional Deficiencies:**
