A nail disorder is a condition in which the nails are affected by trauma, imbalance, or disease in the body. One such state is known as eggshell nails. People with this nail disorder have curved, thin, white, and very brittle nails, like the white of an egg. This article explores this topic, technically known as hapalonychia.
How Nails Become Fragile Like an Eggshell
A key part of the nail’s anatomy is the matrix. A nail rests on this tissue. This tissue contains blood vessels, lymph, and nerves. It is a part of the nail bed (the skin beneath the nail plate) that extends below the nail’s root. This tissue produces the cells that make the nail plate.
Factors like the matrix’s size, thickness, and length determine the nail plate’s thickness and width. The latter’s flatness or being arched by nature is decided by the shape of a finger’s tip. Proper nutrition and care of the matrix support healthy nail growth. In a healthy matrix, cells in the older nail plate are continuously replaced by new ones.
Nails similar to an eggshell are formed when a defect affects the matrix. As a result, the nails soften. They become prone to injury, and even slight pressure can bend or break them.
Eggshell nails can signal underlying health conditions. Hormonal imbalances, thyroid issues, or chronic stress may weaken the matrix. Recognizing these causes can lead to better management of nail health through targeted treatments.
Stresses, improper diet, usage of certain medications, presence of medical complications, or nervous disorders are some of the causes which lead to a defect in the nail’s matrix.
What Are the Symptoms of Eggshell Nails?
Eggshell nails are easy to spot once you know the signs. The nail plate turns thin and soft. They bend and break with very little pressure. Look for these signs:
- Thin, weak nails that split or tear easily
- Soft nails that bend with light pressure
- A white, pale, or bluish tint, sometimes see-through
- Nails that curve down at the free edge
- A rough or flaky nail surface
The problem can affect one nail or many. It shows up more on the fingers than on the toes.
What Causes Eggshell Nails?
Eggshell nails point to a problem in the nail matrix, the tissue where the nail grows. Many things can weaken it. The main causes fall into a few groups.
| Cause Group | Examples |
|---|---|
| Diet and deficiency | Low iron, vitamin B12, vitamin A, vitamin C, calcium, or protein |
| Health conditions | Thyroid problems, rheumatoid arthritis, poor circulation (Raynaud’s) |
| Medicines | Some long-term drugs, such as oral retinoids |
| Lifestyle and environment | Too much water, harsh cleaning chemicals, nail polish remover |
| Other | Long-term stress, nerve problems, or an inherited trait |
Since the cause can be inside the body, long-lasting eggshell nails are worth a check with a doctor.
Treatment of Eggshell Nails
The best home remedy for this nail disorder is to grow awareness of the role played by nutrition in nail care. Intake of appropriate nutrients through food can treat this condition naturally.
Vitamin A: The nutrient vitamin A is vital for its role in cell division all over the body. When the body lacks this nutrient and calcium, and vitamin D, the nails become brittle and dry.
Fresh Vegetables: Fresh vegetables, juices, cereals, milk, fish liver oil, and saltwater fish are rich sources of these micronutrients.
Vitamin B12: Lack of Vitamin B12 in the body can turn the nails dark, excessively dry, and with rounded or curved ends. The nails can develop vertical and horizontal ridges, too if this nutrient is taken below the recommended daily intake. Rich sources of this vitamin include animal kidney and liver, dairy products, and chicken.
Iron deficiency: While iron deficiency can leave the nails brittle and thin, they can easily split owing to the low levels of the substance Linoleic acid. Lower iron intake can also make the nail surface concave instead of convex. This, in turn, increases the chances of nail trauma.
Vitamin C: Vitamin C, protein, and fatty acids are the other essential nutrients required in adequate amounts for treating the symptoms of eggshell-type nails. Adopting good nail care practices like pedicures, manicures, and proper cutting and trimming of the nails from time to time can go a long way toward avoiding nail disorders.
Medications: Some of the prescribed medicines could also cause this problem. These medicines could hinder the flow of essential nutrients to the nails, which could cause this problem. Consult your doctor if you are taking medications.
Regular nail hydration with oils like almond or coconut strengthens brittle nails. Wearing gloves during chores also helps protect nails from harsh chemicals amd promotes healthier nails.
For those with recurring nail issues, biotin supplements help. Studies show biotin supports keratin production, which strengthens nails. Always consult a healthcare provider before adding supplements.
Eggshell Nails vs Other Nail Disorders
Eggshell nails are one of many nail problems, and they are easy to confuse with others. Here is how they compare.
| Nail Disorder | Main Sign | Common Cause |
|---|---|---|
| Eggshell nails (hapalonychia) | Thin, soft nails that curve down and bend easily | Poor nutrition, illness, or medicines |
| Spoon nails (koilonychia) | Thin nails that scoop inward like a spoon | Often iron deficiency |
| Brittle splitting (onychoschizia) | Nails that peel and split in layers at the tip | Too much water and harsh chemicals |
| Nail lifting (onycholysis) | Nail lifts away from the skin below | Injury, infection, or thyroid issues |
| Clubbing | Nails widen and curve over rounded fingertips | Heart or lung problems |
If your nails look scooped like a spoon, that points more to iron deficiency. You can read about spoon nails at the Cleveland Clinic.

What vitamin deficiency causes eggshell nails?
Low levels of iron, vitamin B12, vitamin A, vitamin C, and calcium are common triggers. A blood test can show if you are short on any of these.
