Vertical Ridges (Longitudinal Striations): These are thin, raised lines that run from the cuticle to the tip of the nail. They are common and often associated with aging.
Horizontal Ridges (Beau’s Lines): These are depressions that run across the width of the nail. They may indicate a disruption in nail growth.
Discolored Stripes: These can range from white to dark brown or black and might appear as a single stripe or multiple bands.
Muehrcke’s Lines: These are white, paired lines that do not move as the nail grows. They can be a sign of specific health conditions.
Understanding the type of stripe on your nails is the first step in identifying potential causes.
Causes of Striped Nails
Striped nails can result from various factors, ranging from benign to serious. Below are some common causes:
1. Aging
Vertical ridges are often a natural part of aging. As we grow older, the body produces less oil and moisture, which can affect nail health. These ridges are usually harmless and do not require medical attention.
