Toenails vs. fingernails
Fingernails and toenails are both made of a tough protective protein called keratin. They consist primarily of the nail plate, the nail matrix, and the nail bed below it, with the nail matrix being the part where nails start to grow. The nail bed is the vascular epidermis on which most of the nail rests, and it often has a longitudinally ridged surface that can be seen through the nail. The eponychium, or cuticle, is the thickened layer of skin surrounding fingernails and toenails.
Fingernails grow faster than toenails, with an average growth rate of 3.47 mm per month, compared to 1.62 mm per month for toenails. This difference in growth rate may be attributed to several factors. Firstly, the dominant hand's nails tend to grow faster due to increased usage, which leads to more trauma and an influx of nutrients to the area, promoting nail growth. Fingernails are also more susceptible to trauma and injury than toenails, which can stimulate circulation in the nail bed and accelerate nail growth. Additionally, the growth rate of nails is influenced by genetics, overall health, age, hormone levels, and diet.
The rate of nail growth can vary depending on the finger or toe. For example, the little finger's nail grows slower than the other fingernails, while the big toenail grows faster than the other toenails. The growth rate of nails also changes with age, typically slowing down as individuals get older due to a decrease in the activity of the nail matrix and blood circulation.
Nail care is important for both fingernails and toenails. Regular trimming and filing can help maintain their health and appearance. Fingernails have a functional purpose, protecting the fingertip and enhancing delicate movements, while toenails are less crucial for grip and precision. Toenails are more prone to specific conditions, such as ingrown toenails (onychocryptosis) and infections caused by dirty socks, aggressive exercise, tight footwear, or walking in unclean environments.
In summary, while both fingernails and toenails serve protective functions and share similar structures, their growth rates differ significantly. Fingernails grow faster and are more susceptible to trauma, while toenails have a slower growth rate and are less exposed to external factors. Nail health is influenced by various factors, including genetics, age, and overall health, requiring proper care and attention.

Diet and nutrition
Firstly, a diet rich in protein is essential for nail growth. Protein aids in the formation of keratin, a hard protein that makes up the layers of fingernails. Good sources of protein include salmon, eggs, meat, poultry, and dairy products. Additionally, nutritional yeast and lentils are excellent vegan sources of protein, which is necessary for keratin formation.
Secondly, vitamins and minerals are vital for nail health. Vitamin B12, found in salmon and other meats and dairy, is important for healthy red blood cell development and can prevent nail discolouration. Biotin, a type of B vitamin, helps convert food into energy and strengthens hair and nails. Eggs and lentils are good sources of biotin, which contributes to nail thickness. Vitamin D, found in salmon and eggs, is also important for nail health, and its deficiency can lead to dry and brittle nails. Omega-3 fatty acids, found in flaxseed, are beneficial for cell structure, leading to stronger nails. Iron is another critical mineral, and its deficiency can result in brittle or dented nails. Lentils and beans are rich in iron and help prevent anemia, which can affect nail health.
Thirdly, hydration is essential for nail growth. Water aids in delivering nutrients and oxygen to the cells, promoting nail health. Dehydration can cause brittle and dry nails, so it is important to stay properly hydrated by drinking water and consuming hydrating foods like fruits, vegetables, yogurt, and soups.
While there is no proven way to accelerate nail growth, a well-balanced and nutrient-dense diet can strengthen nails and promote their growth over time. Additionally, maintaining proper nail grooming habits and avoiding biting or picking can support nail health and growth.

Genetics
Genetic factors interact with other factors, such as overall health and lifestyle, to influence nail growth. For example, a balanced diet rich in essential nutrients like biotin, protein, vitamins A, C, D, E, and minerals like zinc and iron promotes nail growth. Good blood circulation also contributes to faster nail growth by ensuring the nails receive adequate nutrients and oxygen.
Age is another factor that impacts nail growth, with younger individuals typically experiencing faster nail growth compared to older adults. Hormonal changes, such as during puberty or pregnancy, can also affect nail growth rates. Environmental factors, such as temperature and climate, play a role as well, with warmer climates and seasons promoting faster nail growth.
While nail growth is influenced by various factors, genetics set the baseline and play a significant role in determining the speed at which nails grow. Maintaining good nail hygiene, a balanced diet, and overall health can help support optimal nail growth within the context of individual genetic factors.

Age and sex
The rate of nail growth depends on a variety of factors, including age, sex, handedness, season, exercise level, diet, hereditary factors, and overall health.
Age
Nail growth tends to peak during puberty and decline as hormone levels balance out with age. Bruce Robinson, a clinical instructor of dermatology, notes that fingernails "reach their peak growth in the second and third decades, with a slight decline thereafter." This decline may be attributed to a decrease in blood flow with aging. Dr. William Bean observed that his left thumbnail grew at a rate of 0.123 mm per day at age 23, but this rate dropped to 0.095 mm per day by age 67.
Sex
The sex of an individual may also influence nail growth rates, with some sources suggesting that men tend to have faster nail growth than women. However, it is important to note that nail growth can be faster in women during pregnancy due to hormonal changes.

Lifestyle factors
Diet and Nutrition
The food you consume has a notable impact on nail growth. A balanced diet rich in essential nutrients is key to supporting nail health and growth. Specifically, include nutrient-dense foods such as eggs, nuts, seeds, and legumes in your diet. These foods provide essential nutrients like protein, biotin, vitamins A and D, zinc, and iron, all of which promote stronger and faster nail growth. A modern diet, rich in protein from readily available sources like fish, meat, eggs, and poultry, may be a contributing factor to the increased trend in nail growth rate.
Exercise and Physical Activity
Physical activity and exercise levels can also influence nail growth. Good blood flow and circulation are essential for nail growth, as they ensure that your nails receive the necessary nutrients and oxygen. Exercise can promote healthy blood circulation, thereby supporting nail growth.
Sun Exposure and Seasonal Variations
Nails tend to grow faster in the summer, and this may be attributed to increased sun exposure and the resulting boost in vitamin D levels. Additionally, people tend to drink more water during warmer months, which can flush out toxins and contribute to overall health, positively impacting nail growth.
Nail Care and Grooming Habits
Practicing good nail hygiene and gentle nail care can promote nail growth and overall nail health. This includes keeping your nails clean, regularly trimming them with a clean pair of clippers, and maintaining your cuticles. While nail biting (onychophagia) has been associated with faster nail growth, it can damage the nail matrix and bed, leading to potential nail problems. Instead, regular nail clipping is recommended as a safer way to stimulate nail growth without the same risks as nail biting.
Stress and Lifestyle Choices
Lifestyle choices, including stress levels and manual labour, can impact nail growth. Higher stress levels can affect overall health, including nail growth. Additionally, manual labour or using your nails as tools can damage nails and slow their growth.
While some of these factors are beyond your control, adopting healthy lifestyle habits and nutritional practices can positively influence nail growth and overall nail health.
