A narrow black line that has formed vertically underneath your nails is called a splinter hemorrhage.

In some cases, these lines are harmless.

But they can also be a sign of a serious health condition.

You might have noticed these black lines.

And now you are wondering how to get rid of black lines on nails.

Read on to understand the causes and the natural treatments for the condition.

What are the black lines on nails?

The condition is known as splinter hemorrhage.

It looks like a wood splinter under your nails.

Caused by damaged small blood vessels underneath your nail, the characteristics of the condition include:

  • Black or reddish brown lines in color
  • It doesn’t change appearance when you apply pressure to the nail
  • It appears on one or more places on your nails

What is causing your black lines on nails?

There are common, and safe conditions that cause black lines, and some not so safe.

The black lines can be a result of many different health conditions.

One of the most is trauma, when something hurts your nail bed and bursts a blood vessel under your nail.

You might even experience nail trauma without knowing.

For example, when you squeeze something very tightly.

With that in mind, let’s break down the causes.

Common and safe causes

In addition to trauma, a common cause of black lines on nails is a nutritional deficiency.

This happens when you are not consuming enough healthy and nutrient dense foods.

Nutritional deficiency is considered rather safe and easy to treat the condition.

Fungal infections due to poor hygiene or exposure to dirty surroundings also fall into this category.

In terms of trauma, you can experience black lines after hitting hard surfaces or squishing your fingernails between a door.

Not cause for an alarm

During pregnancy, the black lines are normal as they happen due to hormonal changes.

Black lines can also appear as you age.

They are more common in dark-skinned people.

So these are health conditions that should not alert the red panic button.

Serious causes

Some of the more severe conditions include melanoma.

Black lines are a common symptom of melanoma, which is a condition in which your body produces an excessive amount of melanocytes.

While the condition is not malignant, you should check with a physician.

Endocarditis is a health condition that can also cause splinter hemorrhages.

In fact, 15% of patients with the condition have black lines on nails.

Endocarditis happens when the inner chambers or valves of the heart have an infection.

Psoriasis is another serious health condition that can cause splinter hemorrhage.

The chronic skin condition manifests as silvery plaques or scales on the skin.

Statistics show that 50% of those with psoriasis have black lines and other nail conditions.

Some other serious health condition causes include lupus, vasculitis, infections, nail fungus, lichen planus, Raynaud’s disease, kidney diseases, lung diseases, circulatory diseases, or as a side effect of chemotherapy.

How to remove black lines naturally

You need to consume more nutrient-dense foods.

If you are deficient in some nutrients and it shows on your nails, it is time to eat more fruits and veggies.

Some of the best healthy foods include dark greens, eggs, fish.

Other foods that are rich in iron, zinc and vitamin C are also required.

Coconut oil also has some potent antifungal properties.

More importantly, the oil will create a barrier on your nail to protect against moisture.

We all know that moist areas are perfect breeding ground for bacteria and fungus.

All you have to do is apply coconut oil directly on the nail three times per day.

Lemon for fungus infections

This citrus fruit is perfect for this condition.
