Several factors influence nail growth, including age, genetics, lifestyle, and overall health. While fast-growing nails are often a sign of good health, they can also be a result of hormonal changes during puberty or pregnancy. On the other hand, slower nail growth can indicate nutritional deficiencies or medical conditions such as thyroid disease or diabetes. Although there are no scientifically proven methods to accelerate nail growth, certain habits like nail biting or using glue-on artificial nails can weaken nails and hinder their growth. Maintaining a well-balanced diet, proper nail care, and using supplements like biotin can help strengthen nails and promote healthier growth.

What You'll Learn
The impact of age on nail growth
The growth rate of nails is influenced by a variety of factors, including age, finger, overall health, and external factors such as temperature and lifestyle. Typically, nail growth slows down as we age. The average growth rate of nails is around 3mm per month, with a normal range of 1.8 mm to 4.5 mm. From as early as age 20, the growth rate slows by about 0.5% per year.
The nails on the dominant hand tend to grow faster due to more frequent use, which increases the risk of trauma and injury. This results in the body sending more blood and nutrients to the area, promoting nail growth. Similarly, jobs that require frequent hand use, such as typing or playing musical instruments, can also stimulate nail growth.
Hormones play a significant role in nail growth regulation. For instance, during pregnancy, increased estrogen levels lead to faster nail growth, while menopause is associated with decreased estrogen levels and a corresponding slowdown in nail growth. Puberty is another critical period for hormone fluctuations and nail growth, with nail growth peaking during this time.
In addition to slowing growth, aging can cause nails to become brittle, dull, and prone to breaking. They may also develop ridges, pits, or changes in shape and thickness, which could indicate underlying health issues. Conditions like psoriasis and rheumatoid arthritis can lead to thicker nails, while fungal infections, common in older adults, can cause nail thickening and discolouration.
While there are no scientifically proven methods to make nails grow faster, maintaining good nail hygiene and overall health can positively impact nail growth and strength. Keeping nails clean, trimmed, and moisturized can prevent breakage and support longer nail growth.

Hormones and their effect on nail growth
Hormones play a crucial role in regulating nail growth. Thyroid hormones, such as thyroxine and triiodothyronine, are particularly influential in nail growth regulation. Hormonal fluctuations can significantly impact the rate of nail growth.
During pregnancy, for instance, increased estrogen levels contribute to faster nail growth. On the other hand, menopause is associated with decreased estrogen levels and a corresponding slowdown in nail growth. This relationship between hormone levels and nail growth is also evident in conditions like thyroid disease, where hormonal changes can manifest as fragile, slow-growing nails.
Additionally, androgen hormones, such as testosterone and DHEA, are known to influence hair growth. Imbalances in these hormones can lead to hair loss and unwanted body hair growth. While the direct connection between androgen hormones and nail growth is less clear, healthy nails require adequate stomach acid for the absorption of amino acids and minerals, and testosterone plays a role in protein synthesis, which is essential for nail health.
Hormonal changes due to illness or medication can also impact nails. For example, chemotherapy affects the entire body, including hormonal balance, which can lead to changes in nail composition and growth. Similarly, menopause can cause nails to become drier and more brittle, affecting their overall health and growth.
While hormonal changes can influence nail growth and health, it's important to note that nail growth is also affected by various other factors, including age, overall health, lifestyle, and environmental conditions.

Trauma and its influence on nail growth
Trauma to the nail can cause a range of issues that affect nail growth and appearance. The most common cause of nail trauma is injury, which can result in blood under the nail, known as a subungual haematoma. This can be caused by stubbing a toe, catching a finger in a door, or hitting a nail on a hard surface. More severe trauma, such as crushing injuries or deep cuts, may result in long-term or permanent damage if the nail matrix is significantly affected.
The nail matrix, located at the base of the nail, is responsible for producing new nail cells. When new cells form, older cells are pushed outwards, hardening to form the visible nail plate. Trauma that damages the nail matrix can disrupt the normal growth cycle, leading to visible changes in the nail as it grows out. These changes may include thickening, ridging, discolouration, or a rough texture. In some cases, the nail may grow more slowly or even stop growing temporarily as it recovers from the injury. Severe injuries involving the nail matrix may result in long-term issues such as chronic thickening, uneven growth, or complete and permanent nail loss.
Following trauma, it is important to recognise changes in nail growth to guide treatment decisions. Minor trauma may heal without intervention, but keeping the area clean can promote recovery. Significant trauma or pain may require the help of a dermatologist. Treatment options can include trimming damaged sections, draining blood under the nail, or, in severe cases, surgical procedures.
Additionally, certain habits can cause trauma to the nails, such as nail biting, cuticle biting, and using nails as tools. These habits can lead to slower nail growth and other nail problems, such as short, uneven nails and missing or ragged cuticles. Therefore, it is important to break these habits to maintain healthy nail growth and appearance.
In summary, trauma to the nail can cause both short-term and long-term changes in nail growth and appearance. Recognising these changes and seeking appropriate treatment are crucial for restoring nail health and aesthetics.

Nutritional factors that affect nail health
Nutritional factors play a significant role in nail health, and deficiencies in certain vitamins, minerals, and nutrients can negatively affect nail appearance and strength. Here are some nutritional factors that can influence nail health:
Biotin
Biotin, also known as vitamin B7, is essential for nail health. It helps strengthen brittle nails and improve their growth. Biotin is found in organ meats, egg yolk, dairy products, yeast, salmon, avocado, sweet potato, nuts, seeds, and even cauliflower. A 2007 study found that taking 2.5 milligrams of biotin daily reduced breakage and improved overall nail health.
Iron
Iron is crucial for providing cells with adequate oxygen, which is necessary for healthy nails. An iron deficiency can affect the shape and appearance of nails, and it may lead to a condition called spoon nails, where the nail appears concave horizontally or vertically. Consuming iron-rich foods, such as animal sources like beef, chicken, fish, and eggs, or plant sources like dark leafy greens, peanuts, seeds, and beans, can help maintain nail health. Additionally, pairing plant-based iron sources with vitamin C-rich foods, such as oranges and strawberries, improves iron absorption.
Magnesium
Magnesium is involved in numerous bodily reactions, including protein synthesis, which is essential for nail growth. Vertical ridges in nails may indicate a magnesium deficiency. Including magnesium-rich foods in your diet, such as leafy greens, nuts, seeds, and beans, can support nail health.
Vitamin B12
Vitamin B12 plays a vital role in iron absorption and red blood cell development. Both iron and B12 are necessary to keep nails strong and healthy. A deficiency in vitamin B12 may lead to changes in nail colour and other issues. Foods rich in vitamin B12 include animal sources like meat, poultry, fish, dairy, and eggs, as well as plant-based sources like nutritional yeast and fortified foods.
Collagen
Collagen is a popular supplement that has gained attention for its potential benefits for nail health. Studies have shown that ingesting Bioactive Collagen Peptide (BCP) daily can improve nail growth rate and strengthen brittle nails.
While these are some key nutritional factors, it is important to remember that maintaining a well-rounded and nutrient-rich diet is the best way to support nail health. Additionally, environmental, behavioural, and genetic factors can also influence nail growth rate and overall health.

Environmental factors that affect nail growth
Several environmental factors can influence nail growth rates, including temperature, climate, and geographical area. Warmer climates tend to promote faster nail growth compared to colder climates due to increased blood circulation, which delivers essential nutrients to the nail matrix. Geographical area has also been shown to impact nail fluoride concentrations, with varying water fluoride levels influencing nail growth.
Lifestyle factors, such as the type of work an individual does, can also play a role in nail growth. Jobs that require frequent hand use, like typing or playing musical instruments, can stimulate nail growth due to the constant movement and stimulation of the fingertips. Additionally, nail care practices, including regular filing, trimming, and maintaining clean and well-maintained nails, can prevent breakage and facilitate longer nail growth.
Hormonal changes throughout an individual's lifespan can also influence nail growth rates. For example, during puberty and pregnancy, hormone levels can cause rapid nail growth, while menopause and lactation may correspond with slower nail growth.
Certain medical conditions, such as thyroid disease, hypopituitarism, diabetes, osteoporosis, onychomycosis, pulmonary tuberculosis, and syphilis, can also impact nail growth and strength. Skin conditions like severe eczema and psoriasis can affect the nail matrix, leading to temporary nail growth interference and changes in texture or colour.
Overall, while there are various environmental factors that can influence nail growth, it is important to note that individual factors, such as age, genetics, and overall health, also play a significant role in nail growth rates.
