What Causes Vertical Ridges on Nails?

Table of Contents

A frequent alteration that many individuals notice over time is the development of vertical ridges on their nails. These are the small lines that extend from the cuticle to the tip of the nail. The majority of the time, they are completely innocuous and are merely a normal part of the process of aging. However, there are occasions when they might also be a warning that your body requires a little bit of additional attention.

Here’s what you need to know about these nail changes:

 Natural Aging

As we age, our body’s ability to renew skin and nail cells slows down. Vertical ridges, also called longitudinal striations, often appear more prominently with age. This is usually nothing to worry about and just reflects changes in nail texture.

Nutritional Deficiencies

A lack of certain vitamins and minerals can affect nail health:

Iron deficiency (anemia) may cause more noticeable ridges or brittle nails.

Low levels of vitamin B12, magnesium, or zinc may also contribute.
Eating a balanced diet with leafy greens, nuts, seeds, and lean proteins can help support nail health from the inside out.

 Dehydration or Dryness

Dry skin and nails can make ridges stand out more. This can happen due to:

Not drinking enough water

Frequent hand washing without moisturizing

Cold or dry climates

Applying a good natural hand cream or nail oil (like coconut oil or vitamin E) can soften the nails and improve their appearance.

Health Conditions

In some cases, vertical ridges might be linked to underlying health issues such as:

If the ridges come with other symptoms—like nail discoloration, pain, or changes in shape—it’s worth discussing with a doctor.

The vast majority of vertical ridges are perfectly natural and do not give rise to any anxiety. However, your nails can provide you with a number of subtle signs about your general health. Your nails will be grateful to you if you take care of your hands, drink plenty of water, and consume meals that are rich in nutrients.
