What You'll Learn
Factors that influence nail growth
Several factors influence the rate of nail growth, which is about 3.5 millimetres per month for fingernails and 1.6 millimetres per month for toenails. Firstly, age plays a role, with younger individuals tending to have faster-growing nails that slow down as they get older due to a decrease in the activity of the nail matrix, the part of the nail responsible for producing new cells. Hormone levels are also a factor, with nail growth peaking during puberty and declining as hormone levels stabilise with age. In addition, pregnancy can cause rapid nail growth, while lactation may decrease the rate of growth.
Health and lifestyle factors can also influence nail growth. For example, individuals with diabetes or circulatory issues may experience differences in their nail growth and should closely monitor their nails. Certain health conditions, such as severe eczema, psoriasis, and subungual melanoma, can also interfere with nail growth by affecting the nail matrix. Additionally, trauma or injury to the nail bed can impact nail growth, with nail-biting, using nails as tools, or picking at cuticles potentially leading to slower growth or nail problems. Environmental factors may also play a role, with warm weather associated with increased nail growth.
Nutrition is another factor that can influence nail growth. A diet lacking sufficient vitamins and minerals can impact nail health, and specific supplements such as biotin, vitamin C, vitamin E, iron, zinc, and calcium can promote healthy nail growth. Proper nail care, including regular cleaning, trimming, and moisturising, can also contribute to optimal nail growth and overall nail health.
While there are many factors that influence nail growth, it is important to note that individual variations exist, and some factors may be outside of one's control. Consulting with a healthcare professional can provide personalised insights and recommendations for maintaining healthy nail growth.

How to make your nails grow faster
While there are no scientifically proven methods to make nails grow faster, there are several ways to increase the overall health of your nails. Here are some tips to help you achieve stronger and healthier nails that can grow longer:
Diet
Diet is crucial for promoting steady nail growth. A well-balanced diet comprising fresh fruits and vegetables, lean proteins, adequate carbohydrates, and healthy fats is essential for maintaining strong and healthy nails. Additionally, consider taking supplements like biotin, vitamin C, vitamin E, iron, zinc, and calcium if your diet lacks these essential nutrients. Biotin, in particular, has been shown to increase nail thickness and smoothness while reducing nail splitting, thereby supporting faster growth.
Nail Care
Proper nail care and grooming techniques can help strengthen nails and prevent breakage. Keep your nails clean and dry to prevent bacterial growth. Use sharp manicure scissors or clippers to trim your nails straight, rounding the tips into a soft curve. Avoid cutting your nails too short to prevent injury to the nail bed, which can affect nail growth.
Moisturise
Moisturising your hands and nails with lotion or oil is crucial for maintaining nail health. Pay special attention to the cuticles by ensuring they remain well-moisturised, as this will help preserve the cuticle seal and strengthen the nail.
Avoid Nail Biting
Nail biting can cause trauma to the nail bed, stimulating circulation and resulting in faster nail growth. However, this can lead to nail problems and an increased risk of infection. Instead, opt for regular nail clipping or filing to maintain nail length and shape.
Nail Hardeners
Using nail hardeners can help strengthen nails and reduce breakage. However, it is essential to use these products sparingly and avoid prolonged use, as they can break down the nail over time.
Environment
Nail growth tends to be faster during the summer or in warmer environments. This may be due to the increased circulation associated with higher temperatures.
Health and Hormones
Overall health and hormone levels influence nail growth. Younger individuals, particularly men and pregnant women, tend to experience faster nail growth. Certain health conditions, medications, and nutritional deficiencies can contribute to slower nail growth, so it is important to maintain a healthy body to support nail growth and overall well-being.

Nail growth and nutrition
Nail growth rates vary from person to person and are influenced by various factors, including age, hormones, habits, and overall health. Generally, nails tend to grow faster in younger individuals and slow down as we age due to the decrease in activity of the nail matrix, where nail cells are produced. Puberty is typically when nail growth peaks, and it declines as hormone levels balance out over time. Additionally, nails on the dominant hand, usually the hand used most, tend to grow faster. Environmental factors also play a role, with warmer weather associated with increased nail growth.
Nail health and appearance can be indicators of nutrient deficiencies. Ensuring adequate nutrient intake can promote healthy and strong nail growth. Here are some key vitamins and minerals that play a role in nail health:
- Biotin: A rare deficiency, but consuming biotin through supplements or foods can help strengthen nails and improve growth.
- Vitamin B12: Plays a role in iron absorption and red blood cell development. It is necessary for strong and healthy nails, and a deficiency can cause colour changes in the nails.
- Folate (Vitamin B9): Contributes to red blood cell formation and new cell development. A deficiency can cause nail discolouration and make nails brittle.
- Magnesium: Involved in protein synthesis, crucial for nail growth. Vertical ridges in nails may indicate a magnesium deficiency. Whole grains, dark leafy greens, quinoa, almonds, and legumes are good sources.
- Vitamin C: Essential for collagen production, which provides strength and structure to nails. Found in citrus fruits, strawberries, bell peppers, and broccoli.
- Zinc: Required for the growth and division of cells, including nail cells. Inadequate intake can lead to white spots on nails and slow growth. Oysters, beef, pumpkin seeds, and chickpeas are good sources.
- Vitamin E: A powerful antioxidant that protects nails from damage and supports growth by improving blood circulation. Found in almonds, sunflower seeds, spinach, and avocados.
- Iron: Crucial for producing haemoglobin, which delivers oxygen to nail cells. Low iron can lead to brittle, ridged, or spoon-shaped nails. Include iron-rich foods like red meat, poultry, fish, lentils, and fortified cereals in your diet, along with vitamin C-rich foods to enhance absorption.
While these nutrients are essential for nail health, it is also important to maintain overall hydration by drinking enough water and consuming hydrating foods. Additionally, limiting high-sugar and processed foods can help reduce inflammation and strengthen nails.

Nail growth and age
Fingernails grow at a rate of about 3.47–3.5 millimetres per month or 0.1 millimetres per day. Toenails grow at a slower rate of around 1.6–1.62 millimetres per month. However, these rates vary from person to person and are influenced by factors such as age, health, hormones, and habits.
Nail growth is said to peak during puberty and then slow down as hormone levels stabilise with age. The nail matrix, where nail cells are produced, becomes less active over time, resulting in decreased nail growth. As early as the age of 20, the growth rate slows by about 0.5% per year. This change in speed may be attributed to the slowing of blood circulation with age.
In addition to age, various health conditions and external factors can affect nail growth and appearance. For example, conditions like anemia, hardening of the arteries, and hormonal imbalances can cause changes in nail texture. Nails may become thicker or thinner with age, and fungal infections, which are common in older adults, can lead to nail thickening and discolouration. Repeated exposure to moisture, harsh chemicals, or cosmetics can also impact nail health and growth over time.
Lifestyle factors, such as nail-biting, using nails as tools, or picking at cuticles, can also influence nail growth. Trauma or injury to the nail bed may result in slower nail growth or nail problems. Ingrown toenails, for instance, can be caused by tight shoes or foot deformities and are more common in older individuals, leading to pain and walking difficulties.
While there are no scientifically proven methods to accelerate nail growth, maintaining overall health and caring for your nails can promote stronger and healthier nails. Ensuring adequate vitamin and mineral intake, including biotin, vitamin C, vitamin E, iron, zinc, and calcium, can support nail growth. Additionally, taking biotin supplements has been shown to reduce nail breakage and improve overall nail health.

Nail growth and the seasons
Fingernails grow at a rate of about 0.1 millimetres per day, which is approximately 3.5 millimetres per month. Toenails, on the other hand, grow at a slower rate of about 1.6 millimetres per month. The exact mechanisms that control the speed of nail growth are unknown, but it is influenced by a variety of factors, including age, health, hormones, and habits.
Nail growth rates vary from person to person, but generally, nails grow faster in younger individuals and slow down as we age. This is because the nail matrix, where nail cells are produced, becomes less active over time, resulting in decreased nail growth. Puberty is a time when nail growth peaks due to fluctuating hormone levels, and it then declines as hormone levels stabilise with age.
The seasons can also impact nail growth. Nails typically grow faster during the warmer months of summer and at a slower rate during the colder months of winter. This may be attributed to the increase in blood circulation during warmer weather, providing more nutrients to the nail bed and accelerating nail growth.
Additionally, nails on the dominant hand tend to grow faster, possibly due to increased usage and subsequent trauma, which stimulates circulation in the nail bed. Similarly, nail growth can be influenced by overall health and nutritional status. For example, individuals with chronic conditions such as psoriasis, endocarditis, lupus, kidney disease, thyroid disease, or liver disease may experience inhibited nail growth. Maintaining a healthy diet with sufficient vitamins and minerals is essential for promoting healthy nail growth.
While there are no scientifically proven methods to accelerate nail growth, certain practices can strengthen nails and prevent breakage, allowing them to grow longer. These include taking biotin supplements, using nail hardeners sparingly, and practising good nail hygiene by regularly trimming and grooming nails.
