What You'll Learn

Nails grow about 1-2 millimetres a week
Nails grow relatively slowly, at a rate of about 1-2 millimetres a week, or 0.1 to 0.15 millimetres per day. This equates to around 2-3.5 millimetres per month, or 3.47 millimetres per month according to one source.
The rate of growth depends on several factors, including age, genetics, overall health, and nutrition. For example, nail growth slows with age due to a decrease in blood circulation. Hormones can also affect nail growth; for instance, pregnancy results in rapid nail growth, while lactation decreases the rate of growth.
Nutrition is another important factor in nail growth. A diet low in biotin, iron, zinc, protein, magnesium, and other nutrients can lead to weak and brittle nails. Taking a biotin supplement or consuming foods rich in biotin, such as fish, nuts, eggs, and green vegetables, can help to maintain healthy nails and promote stronger nail growth.
In addition to nutrition, protecting your nails from damage and keeping them healthy can help them reach their maximum growth potential. This includes keeping your nails dry to avoid weakening them, wearing rubber gloves when washing dishes or gardening, filing your nails into a rounded or squared-off shape to prevent snags and breaks, and moisturizing your cuticles with oils such as apricot, coconut, or sweet almond oil.

Keep nails dry to avoid tearing
On average, fingernails grow about a tenth of a millimeter per day, but this can vary depending on various factors, such as age, genetics, overall health, and nutrition. To promote nail growth, it is essential to maintain a healthy lifestyle and ensure proper nutrition.
Now, onto the focus of this discussion: keeping nails dry to prevent tearing. Here are some detailed tips to help you achieve this:
Keep Nails Moisturized:
Hydration is crucial for nail health. Dry nails are more susceptible to breakage, so regular moisturizing is essential. Use a good quality hand cream or cuticle oil to keep your hands and nails hydrated. Cuticle oil helps maintain moisture, preventing dryness and brittle nails.
Nail-Friendly Diet:
Your diet directly impacts the health of your nails. Incorporate foods rich in biotin, vitamin E, and omega-3 fatty acids. These include eggs, nuts, avocados, and salmon. These nutrients promote nail strength and growth, helping to keep your nails strong and less likely to tear.
Avoid Harsh Chemicals:
Be cautious when using nail polish removers and cleaning products, as they often contain harsh chemicals that can weaken your nails. Opt for acetone-free nail polish removers, and always wear gloves when handling household cleaning products to protect your nails from exposure to harsh chemicals.
Gentle Nail Handling:
Avoid using your nails as tools for tasks like opening cans or scratching off stickers. Treat your nails gently and avoid picking or biting them. Nail biting can damage not only your nails but also the surrounding skin, making your nails more prone to tearing.
Protect Nails During Household Chores:
When performing tasks that can be harsh on your nails, such as dishwashing or gardening, wear gloves to protect your nails from excess water exposure and potential damage. This simple step can make a significant difference in keeping your nails strong and healthy.
By following these tips, you can effectively keep your nails dry and reduce the risk of tearing. Remember, maintaining healthy nails is more important than their growth rate, so take care of your nails and provide them with the nourishment and protection they need.

Take biotin supplements to strengthen nails
On average, fingernails grow about a tenth of a millimetre per day, but this can vary depending on several factors, including age, genetics, overall health, nutrition, and hormone levels. For example, the nails on your dominant hand tend to grow faster, and nail growth is typically faster during the summer.
To achieve stronger and healthier nails, it's important to maintain a healthy lifestyle and ensure you have a nutritious diet. A balanced diet that includes vitamins like A, C, E, and biotin can help maintain healthy nails. Biotin, also known as vitamin B7, is an essential nutrient that supports your metabolism and promotes healthy skin, nails, and hair. While biotin deficiency is rare, taking biotin supplements or including biotin-rich foods in your diet can help strengthen your nails and prevent them from breaking.
Some individuals have reported faster nail growth when taking biotin supplements. In a 2007 study, researchers found that taking 2.5 milligrams of biotin daily reduced nail breakage and improved overall nail health. However, it's important to note that there is limited scientific research to support the claim that biotin directly enhances nail growth.
Biotin is found in various foods, including fish, meat, eggs, liver, salmon, pork, nuts, seeds, and certain vegetables like sweet potatoes and green vegetables. Adult daily multivitamins and prenatal vitamins typically contain the recommended daily value of biotin. If you choose to take biotin supplements, it is recommended to consult with your doctor first, as excessive biotin intake may interfere with certain lab tests.
In addition to biotin, there are other ways to strengthen your nails. Nail hardeners can be used sparingly to reduce breakage, but prolonged use may break down the nail over time. Grooming your nails regularly and maintaining proper nail hygiene are also essential for nail health. This includes washing and drying your hands and nails, using a nail brush, trimming your nails, and applying nail oil or moisturiser to prevent dryness and brittleness. Additionally, gel nails can be considered as they harden your natural nails and make them less prone to damage.

Nails grow faster in summer and during the day
On average, fingernails grow about a tenth of a millimeter per day, or 3.47 millimeters per month. However, there are several factors that influence the rate of nail growth, including the time of day, season, genetics, diet, overall health, age, and hormone levels.
Firstly, nails grow faster during the day and in the summer. This may be due to increased exposure to sunlight and warmer temperatures, which stimulate nail growth by enhancing blood circulation and nutrient delivery to the nail matrix. Warmer climates and higher sun exposure are associated with faster nail growth.
Secondly, genetics play a significant role in nail growth rates. Some individuals are genetically predisposed to faster nail growth, while others may have slower-growing nails due to their genetic makeup. Additionally, the size and shape of nail beds are largely determined by genetics.
Thirdly, diet and nutrition are crucial factors in nail growth. Essential nutrients such as protein, biotin, vitamins A and D, zinc, and iron promote stronger and faster nail growth. A balanced diet rich in these nutrients can contribute to overall nail health and faster growth.
Age is another factor influencing nail growth. Generally, younger individuals experience faster nail growth compared to older adults. This is because the nail matrix, responsible for producing nail cells, becomes less active as we age, resulting in slower nail growth over time.
Lastly, hormone levels can affect nail growth rates. For example, during pregnancy, increased estrogen levels are associated with faster nail growth, while menopause is linked to decreased estrogen levels and slower nail growth. Conditions such as hyperthyroidism, anemia, or diabetes may also influence nail growth rates.
While these factors contribute to faster nail growth during the day and in summer, it's important to note that there are no scientifically proven methods to significantly accelerate nail growth. However, maintaining good overall health, practicing proper nail hygiene, and ensuring adequate nutrient intake can help support the growth and strength of your nails.

Nail biting harms nails and cuticles
On average, fingernails grow about a tenth of a millimeter per day, but this can vary depending on several factors, including age, genetics, overall health, and nutrition. Nails grow at different rates depending on which finger they are on, with nails on the dominant hand and longer fingers growing faster.
Nail biting, or onychophagia, is a common habit that can be challenging to break. Up to 30% of the population bites their nails, and it often starts in childhood as a coping mechanism for emotions like nervousness, boredom, loneliness, or hunger. While it may seem harmless, nail biting can have negative consequences for both your nails and cuticles.
For your nails, biting can damage the tissue that makes them grow, resulting in abnormal-looking nails. It can also increase the risk of breakage, leaving you with shorter nails than if you didn't bite them. Additionally, biting your nails can introduce bacteria and viruses from your mouth to your fingers and face, potentially leading to skin or nail infections.
Nail biting can also harm your cuticles and the surrounding skin. Repeated biting can make the skin around your nails sore and create tiny fissures that can become infected. Over time, this can affect the overall health and appearance of your nails and cuticles, leaving them weak and prone to breakage.
If you want to quit nail biting, there are several strategies you can try. Identifying triggers and finding replacement behaviors, such as using a stress ball or fidget toy, can be helpful. Keeping your nails trimmed short and applying bitter-tasting nail polish can also reduce the temptation to bite. For some, nail biting may be a sign of a more serious psychological or emotional issue, and it's recommended to consult a doctor if you've repeatedly tried to quit without success.
