Types of Nail Stripes

Vertical Stripes

Longitudinal striations or vertical stripes, are common and typically run from the cuticle to the tip. They are often associated with aging, as nail ridges can become more prominent with age.

In some cases, they may be often a mirror of nutritional deficiencies, such as a lack of certain minerals or vitamins (vitamin B12, magnesium, or iron).

Vertical ridges are common with aging and are often harmless. However, if they appear suddenly or become more pronounced, it may be worth checking for conditions like anemia or thyroid issues.

Horizontal Stripes

Horizontal stripes or grooves, also called Beau’s lines, may show more specific health concerns.

These horizontal indentations can appear after physical trauma to the nail, or from serious illnesses or medical conditions, including malnutrition, uncontrolled diabetes, heart attacks or respiratory diseases.
