There are many reasons why your nails may not be growing. Nails serve important functions as protective layers for the fingertips as well as general indicators of health and well-being. A lack of nail growth could be due to a variety of factors, including trauma, disease, lifestyle changes, or simply the process of aging. Nails are made of a protein called keratin, and a well-balanced diet full of fresh fruits and vegetables, lean sources of protein, carbohydrates, and healthy fats can help support nail growth. Additionally, maintaining proper nail hygiene, such as keeping nails dry and clean, using proper tools for trimming, and moisturizing, can also promote nail health and growth. In some cases, nail growth issues may be a sign of an underlying medical condition, and it is recommended to consult a dermatologist or healthcare professional for further advice and diagnosis.

What You'll Learn
Peripheral artery disease
Fingernails serve important functions as protective layers for the fingertips and as general indicators of health and well-being. Poor health can cause nails to grow abnormally. Nails that stop growing can be a sign of underlying medical conditions. One such condition is peripheral artery disease (PAD).
The blockages in the arteries in the legs can also affect other areas of the body, such as the arteries supplying the heart and brain. Peripheral artery disease can lead to poor blood flow in the arms or legs, resulting in poor nutrition and oxygen supply to the fingertips. This, in turn, slows down or even halts nail growth entirely and, in the worst cases, leads to shedding of the plate. Toenails affected by peripheral artery disease may become brittle, change color, or grow thicker.
If you suspect that you have peripheral artery disease, vascular testing can help determine if you have the condition. One common method is vascular testing, which is quick and non-invasive. During this test, your doctor fits you with blood pressure cuffs on your arms and lower legs to compare your ankle-brachial index (ABI). If your ankle reading is significantly lower than your arm reading, it suggests PAD. Your doctor may also perform a pulse volume recording (PVR) test to help determine if your blood flow is limited and, if so, by how much.
Treatment for peripheral artery disease typically involves lifestyle changes, such as exercising and eating a healthy diet, as well as medication. Regular exercise and not smoking are the main lifestyle changes that can ease the symptoms of PAD and reduce the chances of it getting worse. It is also important to address underlying causes, including high blood pressure, high cholesterol, and diabetes.

Poor diet
A well-balanced diet that includes a variety of fruits, vegetables, nuts, seeds, and protein is crucial for nail health. For instance, vitamin A is essential for nail growth, and foods like carrots, sweet potatoes, bell peppers, and spinach are excellent sources of this nutrient. Vitamin C, found in strawberries, kiwis, and citrus fruits, helps produce collagen, boosting nail strength. Iron-rich foods such as broccoli, kale, spinach, and other green leafy vegetables are also vital for maintaining strong nails.
Protein is another key component of a nail-friendly diet. Animal proteins provide zinc, an essential mineral for nail growth. Eggs, a source of protein, offer biotin, which has been scientifically proven to reduce nail brittleness and increase nail thickness. Salmon, a fatty fish, provides healthy fats and omega-3 fatty acids, which contribute to shiny, strong nails. Lean meats like chicken and turkey are also good options, as they provide collagen and protein.
While a plant-based diet can provide adequate nutrition for nail health, it is important to ensure sufficient protein intake. Nuts, seeds, and avocados are excellent sources of healthy fats, supplying the body with magnesium, which is crucial for nail health. Additionally, calcium and vitamin D, found in dairy products, play a role in growing strong, healthy nails.
Overall, a balanced and nutritious diet that includes a variety of food groups is the best way to promote nail health and support their growth.

Hormones
Sex hormones, such as estrogen, progesterone, and testosterone, also influence nail growth and health. Estrogen, in particular, helps maintain hydration in body tissues, including nails. Therefore, lower estrogen levels can contribute to dull, yellowish fingernails. During pregnancy, the surge in estrogen and progesterone levels leads to rapid nail growth in many women. However, some women may experience increased nail splitting and grooving during this time.
Hormonal fluctuations during menopause can also impact nail health, causing nails to become drier and more brittle. Additionally, high levels of androgen hormones like testosterone, which is common in conditions like PCOS, can affect nail growth and health. PCOS, combined with hypothyroidism or blood sugar irregularities, can lead to the nail plate separating from the nail bed, a condition called onycholysis.
Stress can also influence nail health, as chronically high levels of stress hormones like cortisol may have an impact. Furthermore, dramatic illnesses or thyroid problems can cause hormonal changes that eventually affect the nails. While hormonal birth control pills can alter hormones, their impact on nail growth may take 4 to 6 months to become apparent.

Trauma
When trauma occurs, the impact can disrupt the normal growth cycle of the nail, which begins in the nail matrix, the region responsible for producing the cells that form your nails. Minor injuries can cause noticeable changes in the nail's appearance, such as bruising, ridges, or discoloration. Severe trauma, such as crushing injuries or deep cuts, may result in long-term or permanent effects if the nail matrix is significantly damaged.
In the case of severe trauma, it is recommended to seek professional care. A doctor may decide to perform a procedure called nail trephination, which involves draining the blood trapped under the nail to relieve pressure and aid in the correct growth of the new nail. This procedure must be done within 48 hours of the injury. In some cases, the doctor may need to remove the nail to repair the nail bed and matrix.
To promote healing and reduce the risk of future trauma, it is essential to keep the area clean and protect your nails. This can include wearing protective gloves during repetitive tasks or heavy lifting and maintaining well-trimmed nails.
While nails are replaceable and can usually regrow after trauma, severe cases of matrix damage may result in permanent nail loss or deformities. Therefore, it is important to prioritize the prevention of nail trauma and seek appropriate care when necessary.

Chemotherapy
Nail changes during chemotherapy can be more than aesthetic. Chemotherapy can weaken the immune system, making it less able to fight off bacteria and other invaders. Nails may become brittle and thin, growing slowly and breaking easily. Nails may also lift away from the nail bed or fall off completely, leaving the site open to infectious bacteria. Beau's lines, or horizontal ridges, can also form across nails, indicating that something has interrupted nail growth. Nails may also become dry and develop fungal infections.
To reduce the risk of infection, it is important to treat nails with extra care throughout the course of chemotherapy treatments. Nails should be kept clean and trimmed to help them grow back stronger and more quickly. A biotin supplement may also help strengthen fragile nails, but it is important to consult an oncologist before starting any new vitamins or supplements.
After chemotherapy, nails should begin to grow back, but this can take up to six months for fingernails and a year and a half for toenails. In rare cases, nails may not grow back at all.

Frequently asked questions
There could be several reasons for this. Nails are an important indicator of your overall health and nutrition. Poor health, nutritional deficiencies, hormonal changes, or even certain medications can cause nail growth issues.
Some common health issues that can affect nail growth include peripheral artery disease, psoriasis, and onychomycosis (nail fungus infection). Additionally, conditions like onychomadesis can cause a cessation of nail growth due to various factors such as trauma, disease, or lifestyle changes.
Maintaining nail hygiene, moisturising your hands and nails, and avoiding nail-biting are some good practices to keep your nails healthy and promote growth. You can also try home remedies like cuticle oil and taking supplements like biotin, folic acid, and vitamins to boost nail strength and growth.
If you are concerned about your nail growth, it is best to consult a dermatologist or medical professional. They can examine your nails, provide advice, and recommend appropriate treatments to improve nail health and promote normal nail growth.
