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.
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:
Thyroid imbalance
Rheumatoid arthritis
Peripheral vascular disease
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.
