Fingernails are made of many layers of a hard protein called keratin and usually grow continuously throughout our lives. However, sometimes nails stop growing, which is known as onychomadesis. This can be caused by various factors, including trauma, disease, lifestyle changes, and certain medications. Nails that are slow-growing or refuse to grow can also be a sign of nutritional deficiency or poor health. To promote nail growth, it is important to maintain a healthy diet and take care of your nails through proper grooming and hydration.

What You'll Learn
Peripheral Artery Disease, poor blood flow, and nail growth
Peripheral Artery Disease (PAD) is a condition that affects the arteries outside of the heart, often in the arms and legs. It is caused by a buildup of fatty substances, such as cholesterol, in the arteries, which leads to narrowed arteries and reduced blood flow to the limbs. This results in a decreased supply of oxygen and nutrients to the tissues in the affected areas.
The impact of PAD on nail growth is significant. Poor blood flow to the fingertips or toes caused by PAD can slow down or even stop nail growth entirely. The nails may become brittle, change colour, or grow thicker. In severe cases, the nail plate may shed or fall off due to the lack of nutrition and oxygen supplied to the nail bed.
The treatment for toenails affected by poor circulation due to PAD is to address the underlying PAD itself. This may include lifestyle changes, such as exercising and eating a healthy diet, as well as medications to improve blood flow, such as antiplatelet medications (blood thinners) and medicines that relax blood vessel walls. Vascular surgery may also be an option to improve blood flow, including bypass grafts, angioplasty, and stents.
It is important to note that PAD can lead to more severe complications if left untreated. Poor circulation can result in wounds that don't heal, leading to tissue death and gangrene. Therefore, it is crucial to seek medical advice if you suspect you have PAD or if your nail growth has stopped, as it may indicate underlying medical conditions.
While PAD is a common cause of poor blood flow and nail growth issues, there are other factors to consider as well. These include fungal infections, radiation treatments, nail bed injuries, and other underlying medical conditions. A thorough medical evaluation is necessary to determine the exact cause and appropriate treatment options.

The impact of chemotherapy on nail growth
Chemotherapy is an endurance test for the body, where drugs target fast-growing cells, such as cancer cells, to prevent their growth. However, these drugs also target hair follicles and nail matrices, leading to hair loss and interrupted nail growth. This interruption in nail growth is called onychomadesis, which is characterised by a cessation of activity in the nail matrix. Chemotherapy can cause a variety of nail changes, including changes in colour or texture, nail weakness, nail loss, Beau's lines, and onycholysis.
Beau's lines are horizontal grooves that form across a person's nail, indicating periods of interrupted nail growth. A 2018 case study found that Beau's lines were relatively common in people who had received chemotherapy. Onycholysis is damage to the tissue in the nail bed that keeps the nails in place. This can lead to discomfort and infection, especially if coupled with a low white blood cell count.
The type of nail change a person experiences can depend on the type of chemotherapy drug used to treat them. These changes can take several weeks to develop and generally disappear once treatment is over. A 2020 study found that 38% of people experienced nail-related changes, with melanonychia being the most common side effect, affecting 84% of people.
Toenails can also be affected by chemotherapy, and they may take up to 1.5 years to regrow. Toenail problems may seem minor, but they can reduce a person's quality of life and potentially raise the risk of infection. It is important to practice good nail care during chemotherapy to prevent and manage nail changes. This includes trimming nails carefully, keeping them clean, and avoiding injuries.
In summary, chemotherapy can have a significant impact on nail growth and health. Nail changes can be distressing to patients, and it is important to seek advice from a healthcare professional to manage these changes effectively.

Nail care practices to encourage growth
Nail growth can be influenced by a variety of factors, including age, gender, and health status. While there is no scientifically proven method to accelerate nail growth, certain nail care practices can help strengthen nails and promote healthy growth. Here are some nail care practices to encourage growth:
Maintain a Well-Balanced Diet
Nails are primarily composed of a hard protein called keratin, and their health is often reflective of overall nutritional well-being. Consuming a diet rich in fresh fruits and vegetables, lean proteins, carbohydrates, and healthy fats can contribute to stronger and healthier nails. Additionally, ensuring adequate intake of biotin, a B vitamin, can help strengthen nails and promote growth.
Moisturize and Nourish Your Nails
Keeping your nails moisturized can prevent them from becoming brittle and prone to breakage. Use a good hand lotion and massage it into your fingernails, especially the cuticle area. Natural oils like jojoba oil are highly recommended as they can penetrate the layers of keratin, helping to keep the nail flexible and strong.
Practice Proper Nail Grooming
Regular nail grooming can help boost nail strength and reduce breakage. Trim your nails straight across using sharp manicure scissors or clippers, then gently round the tips into a soft curve. Avoid filing the sides of your nails excessively, as this can weaken them.
Protect Your Nails
When cleaning or using harsh chemicals, wear rubber gloves to protect your nails from exposure to substances that can cause dryness and weakening. Additionally, limit the use of hand sanitizers as the alcohol can dry out your nails. If you use shampoo for oily hair, consider switching to a milder alternative, as shampoos designed to strip oils can also dry out your nails.
Avoid Damaging Nail Treatments
Certain nail treatments, such as gel manicures and acrylic nails, can damage the nail bed and hinder growth. If you choose to polish your nails, opt for regular nail polish and remember to remove it periodically to allow your nails to breathe.
While these practices may not yield immediate results, consistent care and patience can help promote nail growth and overall nail health. If you have persistent concerns about your nail growth, consider consulting a dermatologist or healthcare professional for personalized advice and treatment options.

Diet and nutritional deficiencies impacting nail growth
Diet and nutritional deficiencies can significantly impact nail growth. Nails can act as a window to our internal health, reflecting our nutritional status and overall well-being. Nutritional deficiencies can lead to various nail changes, and a balanced diet is crucial to ensuring nail health.
Vitamin deficiencies, especially a lack of B vitamins, can cause nails to become brittle, weak, and rough, impeding proper nail growth. B vitamins play a vital role in promoting cell growth, and their deficiency can result in thin, soft, and extremely brittle nails, also known as eggshell nails or hapalonychia. Additionally, vitamin C deficiency can lead to splinter hemorrhages, presenting as thin red, brown, or blackish lines under the nails.
Iron deficiency is another common nutritional deficiency that can impact nail health. It can cause nail peeling, and in more severe cases, spoon nails, where the nail appears concave horizontally or vertically. Anemia, often associated with iron deficiency, can also lead to nail changes, including discoloration and slowed growth.
Protein deficiency, observed in conditions like Kwashiorkor, can also affect nail growth. Kwashiorkor is characterised by soft and thin nails, indicating a severe protein malnutrition state. Malnutrition, in general, can result in nail changes, with marasmus, a wasting syndrome, causing fissured nails and impaired nail growth.
Furthermore, restrictive diets that eliminate certain food groups can lead to insufficient intake of essential vitamins, impacting nail health. Conditions like malabsorption syndromes and medical issues affecting nutrient absorption can also contribute to vitamin deficiencies, affecting nail growth. Excessive alcohol consumption, as seen in chronic alcoholism, can interfere with nutrient absorption and lead to nail abnormalities.
To promote nail growth and overall nail health, it is essential to address any nutritional deficiencies. This can be achieved through a balanced diet rich in essential vitamins and nutrients, ensuring adequate intake of B vitamins, vitamin C, and iron. In some cases, nutritional supplements or specific dietary adjustments may be recommended to target specific deficiencies effectively.

Medical conditions causing nails to stop growing
Onychomadesis, or the cessation of nail growth, can be caused by various factors, including trauma, disease, or lifestyle changes. While it is not a disease in itself, it can indicate underlying medical conditions. Here are some medical conditions that can cause nails to stop growing:
- Chemotherapy: Chemotherapy targets rapidly dividing cells, including cancer cells, hair follicles, and nail matrices. As a result, it can lead to hair loss and interrupted nail growth.
- Peripheral Artery Disease: This condition is caused by narrowed arteries, often due to fatty buildup, which leads to poor blood flow in the arms and legs. Consequently, the fingertips receive inadequate nutrition and oxygen supply, slowing down or halting nail growth.
- Psoriasis: Psoriasis is a common chronic autoimmune disease where triggers cause the immune system to attack healthy tissues in the skin, fingernails, and toenails.
- Onychomycosis: Also known as a nail fungus infection, onychomycosis occurs when dermatophytes, yeasts, or molds invade the nail plate and/or nail bed. While often treatable, if left untreated, the infection can worsen, leading to nail detachment and halted nail growth.
- Onycholysis: Onycholysis is characterized by the nail lifting up and detaching from the nail bed. It often occurs due to injury, such as cleaning under your nails with a sharp object.
- Paronychia: Paronychia is an infection characterized by redness and swelling around the nail.
- Onychotillomania: Also known as "washboard nails," onychotillomania is characterized by grooves and ridges in the center of the thumb, resulting from picking or pushing back the cuticles.
- Clubbing: Clubbing causes nails to curve downward, often accompanied by fingertip swelling and spongy-feeling nails.
It is important to note that any changes in nail color, texture, or shape can be a sign of an underlying disease. Therefore, it is advisable to consult a dermatologist if you notice any unusual changes in your nails.
