Several factors can cause nails to stop growing, including trauma, disease, lifestyle changes, and nutritional deficiencies. Nutritional deficiencies, such as a lack of biotin, zinc, iron, or vitamin B7, can weaken nails and slow their growth. Additionally, certain medical conditions like diabetes, hypothyroidism, and peripheral artery disease can impair blood flow to the extremities, leading to poor nail health and slow growth. Understanding the underlying cause of nail growth issues is crucial for addressing the problem and restoring healthy nail growth.

What You'll Learn
Biotin (vitamin B7) deficiency
Biotin, also known as vitamin B7, is vital in converting food into energy and is necessary for producing fatty acids, sugar, and amino acids. A deficiency in biotin can lead to a range of issues, including problems with nail growth.
When the body has lower levels of biotin, it experiences slower cell growth and division, which can manifest as a lack of nail growth. This is because biotin is essential for producing fatty acids, sugar, and amino acids, which are all necessary for healthy cell growth. Nails, primarily made of keratin, are not living tissue, but they still require proper nutrition to grow and remain strong. Biotin deficiency can disrupt this process, leading to slower or stalled nail growth.
In addition to biotin, other nutritional deficiencies can also impact nail health and growth. For example, a lack of zinc can cause nail dystrophy, which is characterized by nail discoloration, distortion, and brittleness. Similarly, iron deficiency can lead to nails becoming spoon-shaped, and vitamin B12 deficiency can cause hyperpigmentation and bluish discoloration of the nails.
It is important to note that nail growth issues can have various causes, including trauma, disease, lifestyle changes, and infections. Certain medical conditions, such as diabetes, hypothyroidism, and peripheral artery disease, can also impair blood flow to the extremities, resulting in poor nail health and slow growth. Maintaining a balanced diet and consulting with healthcare professionals can help address potential deficiencies and promote healthy nail growth.

Folate (vitamin B9) deficiency
Folate, or vitamin B9, is an essential nutrient for nail growth and health. It contributes to red blood cell formation and the development of new cells, which are necessary for nail production. The cells of the nail matrix are some of the fastest-dividing in the human body, and folate plays a crucial role in cell division and DNA synthesis.
A deficiency in folate can cause several issues with nail health and growth. One of the most common signs of folate deficiency is a change in nail pigmentation. Nails may also become rigid and brittle, making them more susceptible to breakage. Additionally, folate deficiency can disrupt the normal growth pattern of the nail, leading to conditions such as onychomadesis, where nail production stops, or the nail plate falls off completely.
The recommended daily intake of folate for adults is 400 mcg, but pregnant women have an increased requirement. Ensuring an adequate intake of folate through a balanced diet or supplements can help prevent deficiencies and maintain nail health. Food sources of folate include leafy greens, citrus fruits, beans, and nuts.
It is important to note that nail problems can also arise from other factors, such as trauma, disease, or lifestyle changes. In some cases, nail issues may be an indication of underlying health conditions. Therefore, if nail problems persist or are accompanied by other symptoms, it is advisable to consult a healthcare professional for personalized advice and treatment options.
Overall, maintaining adequate levels of folate through a well-balanced diet or supplements is crucial for supporting nail growth and overall nail health.

Zinc deficiency
Zinc is an essential nutrient that plays a crucial role in human metabolism and contributes to hair, skin, and nail health. A deficiency in zinc can be caused by a lack of zinc in the diet or an underlying medical condition. It is commonly seen in developing regions due to malnutrition and is associated with aging and chronic illnesses in developed regions.
Zinc is necessary for the body to grow and maintain strong nails. Without sufficient zinc, the rate of nail growth decreases, and nails become fragile. This can lead to various nail conditions, including Beau's nails and onychorrhexis.
To address zinc deficiency, one can increase their intake of zinc-rich foods, such as whole grains, poultry, beans, and beef. Additionally, zinc supplements can be taken under the guidance of a healthcare provider. It is important not to exceed the recommended dosage of zinc supplements unless instructed by a doctor.
Other nutrient deficiencies, such as a lack of biotin (vitamin B7) and folate (vitamin B9), can also contribute to nail health issues. A balanced diet should typically provide all the necessary nutrients for nail health. However, if deficiencies persist, it may be advisable to consult a healthcare professional.

Iron deficiency
Iron is necessary to make new red blood cells. A deficiency in iron may cause nail abnormalities such as spoon nails (koilonychia). Spoon nails are indented nails that look like spoons. They occur when the center of the nail becomes sunken, giving a spoon-like appearance. Spoon nails can also be thin and brittle. Iron deficiency is the most common cause of spoon nails in children.
If you think you have an iron deficiency, it is recommended that you add iron-rich foods to your diet, such as beans, lentils, dark chocolate, fortified foods (bread or breakfast cereal), iron-rich fruit (dates, figs, prunes, and raisins), leafy greens (spinach or kale), meat and seafood rich in iron, and nuts and seeds. If symptoms continue, talk to your doctor.

Vitamin B12 deficiency
While vitamin B12 deficiency is not the only cause of nail growth cessation, it can indeed cause nail growth issues. Vitamin B12 is important for making DNA and red blood cells, as well as for the growth of the central nervous system. A deficiency in vitamin B12 can affect your bones, hair, skin, nails, energy levels, mood, and memory.
In terms of treatment, correcting a vitamin B12 deficiency through supplementation or dietary adjustments may improve overall nail health. However, it may not necessarily lead to a significant increase in nail growth beyond what is considered normal for a specific individual. It is important to note that nail growth is influenced by various factors, including genetics, age, hormonal factors, and overall health.
Other causes of nail growth cessation include fungal infections, trauma, disease, lifestyle changes, and imbalances in the body due to certain diets, drinks, or supplements. In some cases, nail growth issues may be caused by underlying conditions such as psoriasis, endocarditis, or nail melanoma.

Frequently asked questions
There are a few nutritional deficiencies that could be the reason for your nails to stop growing. These include deficiencies in biotin (vitamin B7), zinc, iron, vitamin B12, and selenium.
Biotin is necessary for the process of converting food into energy and is used in the production of fatty acids, sugar, and amino acids. Lower biotin levels in the body can mean slower cell growth and division, which can affect nail growth.
A zinc deficiency can cause nail dystrophy, which is the discoloration and distortion of nails. This includes brittle nails and lines appearing on the nail, such as Beau's lines, which are horizontal ridges.
Iron deficiency can cause nails to become spoon-shaped, a condition called koilonychia. It can also cause nail pallor or pale nails.
Vitamin B12 deficiency can cause hyperpigmentation of the nails with bluish discoloration, blue-black pigmentation, and darkened longitudinal streaks.
