Fingernails are an essential part of the body, serving as protective layers for the fingertips and reflecting our overall health. Nails that are slow-growing, weak, or cracked can be a result of various factors, including nutritional deficiencies, stress, underlying health issues, aging, lifestyle habits, and injuries. Nutritional deficiencies, such as a lack of biotin, vitamin E, iron, and zinc, can hinder nail growth. Stress, underlying health issues like psoriasis, thyroid problems, or anemia, and the side effects of aging can also contribute to weak and brittle nails. Additionally, lifestyle habits like frequent exposure to water, harsh nail products, and nail-biting can damage nails and make them prone to cracking. In some cases, injuries or trauma to the nail matrix, the area responsible for nail growth, can lead to irregular or slowed growth. Understanding and addressing these factors can help improve nail health and promote stronger, healthier nails.

Nutritional deficiencies, such as a lack of vitamins A, B, C, D, E, iron, zinc, or calcium, can cause nails to crack and not grow
Nutritional deficiencies can cause nail issues, including cracking and slow growth. Vitamins A, B, C, D, E, iron, zinc, and calcium are some of the essential nutrients that affect nail health.
Vitamin A is essential for nail health, and its deficiency can lead to soft nails, known as hapalonychia. Vitamin A deficiency has also been linked to longitudinal melanonychia, which is a blackish discolouration of the nail plate.
Vitamin B deficiencies can cause nail ridges and spoon nails, also known as koilonychia. Spoon nails are characterised by a depression in the centre, giving them a concave, spoon-like shape. They are often thin and brittle and can be a sign of iron deficiency anaemia. Vitamin B deficiencies can also cause transverse leukonychia, which is characterised by white nails.
Vitamin C is crucial for collagen production, and its deficiency can lead to nail deformities, including spoon-shaped nails and red lines or spots underneath the nail bed, known as splinter haemorrhages. Vitamin C deficiency is also associated with fatigue, easy bruising, and bumpy skin.
Vitamin D plays a role in nail health, and its deficiency can lead to longitudinal melanonychia of the nail plate. While vitamin E deficiency has not been directly linked to specific nail changes, it has been found to help improve the nail changes associated with yellow nail syndrome.
Iron is essential for nail health, and its deficiency can cause nail ridges and spoon nails. Anaemia, a condition caused by low iron levels, can lead to nail abnormalities, including pale or spoon-shaped nails.
Zinc deficiency can cause white spots and Beau's lines on the nails. Calcium is also crucial for nail health, and its deficiency can lead to thin, weak, and brittle nails that break easily and grow slowly.
Therefore, nutritional deficiencies in vitamins A, B, C, D, E, iron, zinc, or calcium can contribute to nail issues, including cracking and slow growth.
The Health Warning Your Fingernails May Be Issuing

Frequent exposure to water can weaken nails, making them more prone to cracking and slower to grow
Nails are highly porous, so when they come into contact with water, they absorb it and expand. When the water evaporates, the nail cells contract, and this puts a lot of strain on the nail, making it prone to weakening, peeling, and breakage. This process also exposes and enlarges any small fractures in the nail.
If you spend a lot of time with your hands in water, such as when washing dishes, your nails can start to split. This is known as "water damage" and is characterised by soft nails that split and peel easily. It can also lead to 'Green Nail Syndrome', where bacteria grow under the nail plate.
To prevent water damage to your nails, it is recommended to wear gloves when doing household chores or working with water. You can also oil your nails before putting on and after taking off the gloves. Keeping your nails and hands well-moisturised can also help prevent dryness, which makes nails more prone to breakage and infection.
If your nails are already damaged, you can try using a nail and skin oil or lotion to restore moisture. You can also try a nail strengthener to improve durability and encourage growth.

Aging causes nails to dry out and become more fragile, which can result in cracking and slower nail growth
Aging can cause significant changes in the appearance and texture of your nails. One of the most common changes is the drying out of nails, making them more brittle and prone to cracking and breaking. This is due to a decrease in keratin production and thinning of the nail plate, which can result in slower nail growth.
As you get older, your nails may become more fragile and prone to cracking. This is because aging can affect the production of keratin, a protein that gives nails their strength and flexibility. The nail plate, which is made up of layers of keratin, can become thinner and more fragile with age, leading to nail splitting and breakage. This is known as brittle nail disorder, which is characterized by increased fragility of the nail plate and affects around 20% of the population, with a higher incidence in older individuals.
Additionally, aging can cause changes in the shape and texture of your nails. They may become thicker or thinner, with ridges or grooves along the length of the nail. Repeated exposure to water, harsh chemicals, and cosmetics can further contribute to nail dryness and brittleness. Therefore, it is essential to protect your nails by wearing gloves when doing household chores or working with chemicals.
To maintain nail health as you age, it is important to keep your nails moisturized, especially after washing your hands or doing tasks that involve water. Using a lotion with lanolin or alpha-hydroxy acid can help soothe and moisturize your nail area. It is also recommended to limit the use of nail polish and acrylics, as these can weaken the surface of your natural nails over time.
Furthermore, age-related health conditions can also impact nail growth and health. Conditions such as anemia, hardening of the arteries (atherosclerosis), hormonal problems, and thyroid issues can cause changes in nail texture and growth. It is crucial to consult a healthcare professional if you notice significant changes in your nails or suspect any underlying health issues.

Underlying health issues, such as diabetes, thyroid problems, anemia, or peripheral artery disease, can affect nail health and growth
Fingernails can act as a map to what's going on inside the body, revealing clues to one's overall health. While nail abnormalities are rarely the first sign of an underlying health issue, it is still important to be aware of the potential causes.
One underlying health issue that can affect nail health and growth is diabetes. Horizontal ridges, also known as Beau's lines, indicate a pause in nail growth that could be related to diabetes. Additionally, if the nails take on a bluish tinge, it may be a sign that the body lacks adequate oxygen, which can be linked to diabetes or other conditions such as heart disease and emphysema.
Thyroid problems can also impact nail health. Dry, brittle nails that frequently crack or split have been linked to thyroid disease. Thyroid issues can cause nail splitting and brittleness, and may also lead to horizontal nail ridges.
Anemia is another condition that can affect nail health. Anemia is a condition where the body does not have enough iron to produce healthy red blood cells, and one of the symptoms can be cracked nails. Very pale nails can also indicate illnesses such as anemia, as well as congestive heart failure or liver disease.
Lastly, peripheral artery disease can impact nail health and growth. Peripheral vascular disease is listed as one of the potential causes of horizontal ridges in the nails, which is a pause in nail growth.
While these underlying health issues can affect nail health and growth, it is important to remember that nail abnormalities can also be caused by other factors, such as nutritional deficiencies, aging, exposure to water, or certain nail products. If you are concerned about your nail health, it is always best to consult a healthcare professional.

Yeast or mold infections, known as onychomycosis, can invade the nail and cause it to crack and stop growing
Yeast or mold infections, known as onychomycosis, can invade the nail and cause it to crack and stop growing. Onychomycosis is a fungal infection that affects the toenails and, less commonly, the fingernails. It occurs when fungi enter through small cracks or cuts in the nail and the nearby skin, causing an infection that damages the nail by destroying keratin, a protein-rich tissue that forms the main structural material of nails.
The most common type of onychomycosis is caused by a mold called a dermatophyte, which needs keratin to grow. Other causes include nondermatophyte molds, yeast, and ringworm. The infection can start at the tip or sides of the nail and spread, or it can originate from the proximal nail fold. As the infection progresses, the nail may turn white, brown, or yellow, thicken, and separate from the nail bed.
If you suspect onychomycosis, it is important to see a healthcare provider for diagnosis and treatment. They may take a small sample from underneath the nail for analysis or send a scraping to see if the fungus grows in culture. Treatment for onychomycosis can be challenging, and the infection may recur even after successful treatment. Oral antifungal medications are typically prescribed, and in severe cases, surgical removal of the nail may be necessary.
To prevent and manage onychomycosis, it is essential to maintain proper nail care practices. This includes keeping your nails trimmed, washing and moisturizing your hands regularly, and avoiding harsh nail products. Additionally, if your hands are often exposed to water, consider wearing gloves to protect your nails and reduce their exposure to moisture, which can contribute to nail splitting.
