Low levels of iron can cause vertical lines on nails and sometimes nails that look like spoons.
3. Dehydration is when your body loses too much water.
Not drinking enough water can impact your whole body, including your nails. If you don’t drink enough water, your nails can become weak and have lines on them. It’s important to drink enough water to keep your nails and skin healthy.
4. Injury to a fingernail.
Injuries like crushing or constantly picking at your nails can create lines on them. These injuries can harm the skin under the nail and affect how the nail grows.

Some skin problems, like psoriasis or eczema, can lead to changes in the nails, like ridges, especially around the cuticles or the skin near the nail.
