Lines on nails

Lines or ridges on nails? Here’s what you need to know

Lines or ridges in nails are common. Sometimes they are harmless, sometimes they indicate something else. In this overview, you’ll read about the possible causes, how to recognize them, and what you can do to treat or prevent them.

What are lines on nails?

Ridges or lines on the nail can run lengthwise or across. Vertical ridges usually develop with aging and are often harmless. Horizontal ridges are less common and may point to a disruption in nail growth, for example after illness or injury.

Possible causes of lines and ridges

One of the most common causes of vertical ridges is aging. As you get older, these lines become more visible. But deficiencies in vitamin B, iron, or zinc can also affect nail structure. Hormonal changes, such as during menopause, may also play a role.

Frequent exposure to water or cleaning products can dry out and weaken nails. Trauma or injury to the nail can cause temporary growth disturbances. Certain chronic conditions, such as diabetes or psoriasis, can alter nail growth. Medication use may also have an effect.

Dark lines can be caused by pigment cells in the nail. This is called melanonychia.

Vertical ridges on nails

Vertical ridges run from bottom to top across the nail. They are often caused by age, deficiencies such as vitamin B12 or iron, or repeated contact with water and soap. Hormonal fluctuations can also contribute.

Horizontal ridges on nails

Horizontal ridges, also called Beau’s lines, are transverse grooves and usually appear after fever, infection, or injury to the nail matrix. They can also indicate conditions such as kidney disease or diabetes.

White lines on nails

White lines on the nail, called leukonychia, often arise from minor damage to the nail matrix or from a zinc or calcium deficiency. Sometimes they can point to an underlying condition.

Dark lines on nails

Dark lines, known as melanonychia, deserve extra attention. If they become wider, change color, appear suddenly, or are painful, this may indicate melanoma or another serious cause.

What can you do about lines or ridges?

What you should do depends on the cause. If you suspect a nutritional deficiency, discuss with a doctor whether supplements are helpful. In cases of dryness or aging, nail oil or nourishing cream can make the nails more flexible. If symptoms persist or the lines change suddenly, it is wise to seek medical help. In case of injury, it’s most important to rest and protect the nail from further damage.

How to prevent ridges and lines

To prevent lines or ridges, you can follow a few simple habits. Wear gloves when doing household chores to protect your nails from moisture and harsh substances. Keep your cuticles soft with oil or cream. Avoid harsh nail polish removers and take occasional breaks from polish. Eat enough protein, iron, zinc, and B vitamins. File your nails gently and always in one direction to prevent splitting.

When to see a doctor

Visit a doctor if ridges appear suddenly or change quickly. If you also have pain, swelling, or discoloration, your nail should be properly examined. Dark, thick, or irregular lines are always a reason to seek advice. Especially if you have a condition like diabetes, it’s important to take nail changes seriously. Sometimes further testing is needed, such as bloodwork or a nail biopsy. Don’t ignore uncertainty.
