Have you ever noticed those thin, raised lines running from the base to the tip of your nails? These are called vertical ridges (also known as longitudinal ridges), and while they’re common and often harmless, they can sometimes signal something more. Let’s break down the real reasons why they appear and when you should pay attention:
One of the most common causes of vertical ridges is simply aging. As we grow older, the natural renewal of skin and nail cells slows down, leading to subtle changes like thicker or brittle nails and visible ridges or lines. This is perfectly normal and nothing to worry about.
2. Dehydration of the Nail
Lack of moisture, both in the nail and cuticle, can make the ridges more prominent. Causes of dehydration include frequent handwashing, cold, dry weather, and use of harsh soaps or chemicals.
3. Nutrient Deficiencies
Certain vitamin and mineral deficiencies may contribute to vertical ridges, such as iron deficiency (mild anemia), vitamin B12 deficiency, and magnesium or zinc deficiency. If ridges appear suddenly and are accompanied by other symptoms like fatigue, pale skin, or brittle hair, it’s a good idea to check your nutrient levels.
4. Health Conditions
Though less common, persistent or severe vertical ridges could signal underlying health conditions, such as thyroid imbalance (hypothyroidism), digestive issues affecting nutrient absorption, or rheumatoid arthritis.
5. Trauma to the Nail
Repeated minor trauma like nail biting, manicures, or pressure can temporarily disturb nail growth, resulting in ridges.
