What You'll Learn
Fingernails grow at 0.1 mm/day
Fingernails grow at an average rate of about 0.1 mm per day, or 3.47 mm per month. This equates to approximately 0.7 mm per week. This rate of growth varies from person to person and is influenced by factors such as age, genetics, overall health, and nutrition. For example, children's nails grow faster than those of adults, with the growth rate slowing as a person ages. The nails on the dominant hand also tend to grow faster, possibly due to more frequent use.
Hormones can also affect nail growth rates. For instance, pregnancy can cause an increase in nail growth, while lactation may decrease it. Additionally, certain health conditions can impact nail growth, with some studies indicating that warm weather may contribute to increased nail growth.
To promote healthy nail growth, it is important to maintain proper nail care and hygiene. This includes regularly washing and drying the hands and nails to remove dirt and bacteria, using protective gloves when handling harsh chemicals, and applying nail oil or moisturizer to prevent dryness and brittleness. Trimming the nails straight across with rounded edges can also help maintain their health.
While there is no magic solution to speeding up nail growth, taking care of your overall health and nutrition can positively impact nail growth. Eating a nutritious diet, staying hydrated, and taking vitamins that target nail and hair growth can all contribute to stronger and healthier nails.

Toenails grow slower, at 1.62 mm/month
Fingernails and toenails are constantly growing, but at different rates. On average, fingernails grow about 3.47 mm per month, or about 0.1 mm per day. This rate of growth varies depending on factors such as age, health, genetics, nutrition, and hormone levels. For example, children's nails grow faster than adults' nails, and nails grow faster on the dominant hand and longer fingers. Pregnancy also accelerates nail growth due to increased metabolism and circulation. Conversely, health conditions like thyroid disease, diabetes, and osteoporosis can cause fragile and slow-growing nails. Environmental factors, such as warm weather, may also contribute to faster nail growth.
Now, let's focus on toenails, which grow at a slower rate of approximately 1.62 mm per month. This equates to around 0.4 mm per week. Toenails take a considerable amount of time to grow back, typically requiring a year to a year and a half to regenerate from the cuticle to the tip. Maintaining short toenails is essential to minimize the risk of injury and trauma. Additionally, cuticle care is crucial for toenail health, as cutting or pushing back the cuticles can increase the risk of bacterial infections. Applying cuticle oil daily helps keep the cuticles moisturized and prevents the buildup of dead skin on the nails.
The slower growth rate of toenails, at 1.62 mm per month, is influenced by similar factors as fingernails. Age plays a significant role, with nail growth slowing down as individuals advance in age. Health conditions, such as thyroid disease and diabetes, can also impact toenail growth, leading to fragile and slower-growing nails. Environmental factors, such as warm weather, may promote toenail growth, while cold environments tend to slow it down.
While toenails grow at a slower pace, it's important to prioritize their health and maintenance. Keeping toenails trimmed and short reduces the risk of injury. Additionally, maintaining proper cuticle care by avoiding cutting or pushing them back helps protect the nail root and prevents bacterial infections. Applying cuticle oil on a daily basis is beneficial for toenail health, as it ensures that the cuticles remain moisturized and discourages the accumulation of dead skin on the nails.
In summary, toenails grow at a slower rate of 1.62 mm per month, influenced by factors such as age, health conditions, and environmental factors. Proper toenail care, including trimming, cuticle maintenance, and the use of cuticle oil, is essential for maintaining healthy and strong toenails.

Nail growth slows with age
On average, fingernails grow about 3.47 millimeters per month, or about 0.1 millimeters per day. Toenails grow at a much slower rate, averaging 1.62 millimeters per month. However, these rates can vary depending on several factors, including age, hand dominance, finger length, season, and overall health.
As we age, our nail growth tends to slow down. Researchers estimate that by age 20, the growth rate of nails may decrease by approximately 0.5% per year. This deceleration is attributed to various factors. One factor is the increased prevalence of health conditions that impact nail growth in older individuals, such as fungal infections known as onychomycosis. Additionally, changes in hormone levels with age can influence nail growth rates, as seen during pregnancy and lactation.
The curve of nails may also change over time. A significant shape alteration, such as very rounded nails, is called clubbing, indicating long-term oxygen deprivation. It can be a sign of underlying diseases, including kidney, liver, or endocrine disorders, warranting medical attention.
Moreover, nails may exhibit discoloration with age, turning yellow, gray, pale, or opaque. While some discoloration is natural, it can also be a sign of fungal infections or more serious health issues like heart and lung disease, anemia, liver and kidney problems, or diabetes.
To promote healthy nail growth as we age, it is essential to maintain overall health and practice good nail hygiene. Eating a nutritious diet, taking vitamins, and keeping nails clean and trimmed can support nail health and growth. Additionally, addressing any underlying health conditions or hormone imbalances can help mitigate their impact on nail growth.

Hormones and health affect growth
On average, fingernails grow about a tenth of a millimeter per day, but this rate can vary depending on factors such as age, hormone levels, overall health, and even the finger on which the nail is located. The nails on the dominant hand tend to grow faster, as do the nails on longer fingers. Additionally, nail growth is typically faster during the day and in the summer.
Hormones play a crucial role in nail growth and health. Oestrogen, for example, helps keep water in body tissues, contributing to nail hydration. Higher levels of oestrogen during pregnancy can lead to rapid nail growth, while lower levels during menopause or postpartum can result in brittle nails and thinning hair. Androgen hormones like testosterone and DHEA also influence hair growth, and an excess of these hormones can lead to unwanted body hair.
Health conditions and nutrient deficiencies can significantly impact nail growth and appearance. Nails can develop white lines or spots due to injury, and more severe illnesses may cause nail growth to temporarily halt, resulting in horizontal lines known as Beau's lines. Changes in nail colour, such as yellowing or redness, can indicate underlying health issues like liver or kidney problems, respiratory conditions, or even heart disease. Additionally, conditions such as psoriasis, lichen planus, and dermatitis can affect the nails.
Stress levels can also influence nail growth. High-stress situations, such as a serious injury, infection, or fever, can cause nails to stop growing temporarily.
To promote nail growth and health, it is essential to take care of your overall health and well-being. Maintaining a healthy diet, managing stress, and ensuring adequate nutrient intake can all contribute to stronger and faster-growing nails.

Nail care tips for stronger nails
On average, fingernails grow about a tenth of a millimetre per day, but this can vary depending on several factors, including age, hormone levels, overall health, and nutrition.
Keep your nails clean and dry
Bacteria and fungi thrive in a moist environment, so maintaining clean and dry nails is essential to prevent bacteria from growing underneath your nails. Use a clean pair of clippers to trim them regularly, and round the nails slightly at the tips for maximum strength.
Avoid harmful chemicals
Many everyday products, such as hand sanitizers, cleaning products, and shampoos, contain chemicals that can dry out and weaken your nails. Try to avoid getting hand sanitizer on your nails, and always wear rubber gloves when cleaning.
Practice good nutrition
Nutritional deficiencies can lead to brittle nails. Ensure you are drinking enough water and eating a nutrient-dense diet high in protein. Some specific vitamins and nutrients that promote nail health include biotin, collagen, and vitamins A, C, and D.
Protect your nails
Avoid using your nails as tools, such as opening cans, as this can cause damage like chipping or splitting. Additionally, do not bite your nails or remove the cuticle, as this can also weaken the nail.
Consider nail care products
Nail hardeners can strengthen nails and reduce breakage, but they should be used sparingly as prolonged use can break down the nail. Look for nontoxic or water-based polishes, and avoid glue-on nails, as these can increase the risk of breakage.
See a professional if needed
If you have tried various remedies and lifestyle changes without success, consider consulting a dermatologist or healthcare professional. They can help identify any underlying conditions causing nail issues and prescribe appropriate treatments.
