There are several factors that influence the rate of nail growth, including genetics, nutrition, blood circulation, hormones, overall health, age, exposure to injury or trauma, and the environment. Nails tend to grow faster in warmer climates, during the summer, and in individuals with certain medical conditions, such as hyperthyroidism, anemia, or diabetes. Additionally, nails on the dominant hand and longer fingers tend to grow faster, possibly due to increased blood flow and frequent use. While there are no scientifically proven methods to accelerate nail growth, maintaining healthy nails through proper nutrition, regular filing and trimming, and avoiding harsh chemicals can help prevent breakage and create the appearance of faster growth.

What You'll Learn
Genetics, health, and age
Several factors influence the rate of nail growth, including genetics, health, and age. While the average rate of fingernail growth is about a tenth of a millimeter per day, or 3.47 millimeters per month, individual growth rates can vary.
Genetics play a role in nail growth rate, with some people naturally experiencing faster or slower nail growth due to their genetic makeup. For example, a 2007 study found that the little finger's nail grows slower than other fingernails. Additionally, the nails on the dominant hand tend to grow faster, possibly due to more frequent use and increased blood flow to that hand.
Health and lifestyle factors also influence nail growth. Overall health and nutrition impact nail growth, with certain conditions affecting nail growth and recovery. For example, diabetes and circulatory issues can impact nail health and growth. Maintaining good overall health, including proper nutrition and managing any health conditions, can support nail growth.
Hormone levels are another factor that affects nail growth. Puberty, pregnancy, and lactation are associated with fluctuating hormone levels, which can influence nail growth rates. Nail growth is said to peak during puberty and decline as hormone levels stabilize with age.
Age is a significant factor in nail growth. As we age, our blood circulation slows down, which can lead to a decrease in nail growth rate. For example, a study by Dr. William Bean observed that his left thumbnail growth rate decreased from 0.123 mm per day at age 23 to 0.095 mm per day at age 67.
While there are no scientifically proven methods to make nails grow faster, certain practices can improve nail health and reduce breakage, allowing nails to grow longer. These include taking biotin supplements, using nail hardeners sparingly, avoiding glue-on nails and toxic polishes, and opting for non-toxic or water-based alternatives.

Trauma and injury
Nail injuries can result from various causes, such as a blow to the nail, catching the finger in a door or drawer, or ill-fitting shoes. These types of trauma can lead to blood under the nail (subungual hematoma), torn or split nails, or splinters under the nail. Repeated trauma to toenails can result in deformities, such as thickening, discolouration, or lifting away from the nail bed. Habits such as nail biting and cuticle biting can also cause trauma and increase the risk of infection.
Proper nail care and protection can help reduce the risk of trauma and injury. Keeping nails trimmed and maintaining them can minimise the chance of breakage. Wearing protective gloves during repetitive tasks or heavy lifting can also prevent nail injuries. Additionally, wearing properly sized shoes is essential, as tight shoes can cause toenail trauma and deformities.
If nail trauma occurs, treatment depends on the severity of the injury and the specific changes in nail growth. Minor trauma may heal without intervention, but keeping the area clean can promote recovery. In more severe cases, trimming damaged sections, draining blood under the nail, or surgical procedures may be necessary. It is recommended to seek help from a board-certified dermatologist or a doctor if the injury is severe or if there are concerns.
Overall, trauma and injury to the nail can have significant effects on its growth and appearance. Proper care and protection are essential to reduce the risk of trauma and promote healthy nail growth.

Environmental factors
Firstly, temperature and climate influence nail growth. Warmer climates and higher temperatures promote faster nail growth compared to colder environments. This is because heat increases blood circulation, delivering essential nutrients to the nail matrix and stimulating growth. As a result, nails tend to grow faster during the summer.
Secondly, your occupation and daily activities can impact nail growth. Jobs or hobbies that require frequent hand use, such as typing or playing musical instruments, can inadvertently stimulate nail growth due to the constant movement and stimulation of the fingertips.
Additionally, your nail care routine is an important environmental factor. Maintaining clean and well-groomed nails can prevent breakage and allow them to grow longer. Regular filing and trimming can help manage length and create the appearance of faster growth. It is also beneficial to keep nails hydrated with cuticle oils and hand creams, especially after using harsh chemicals or cleaning products.
Furthermore, geographical location and ethnic background can influence nail growth rates. Studies have shown variations in growth rates among different populations, with factors such as genetics and climate likely contributing to these differences. For example, a study of an Indian population found a slightly lower average growth rate than some reported averages in Western populations.
Finally, the time of year can also impact nail growth. Seasonal changes may affect growth rates, with nails potentially growing faster during certain seasons.
While these environmental factors are important, it is worth noting that individual genetics, overall health, diet, and age also play a significant role in nail growth rates, and the combination of these factors results in unique growth patterns for each person.

Diet and supplements
While there are no scientifically proven methods to make nails grow faster, certain dietary changes and supplements can help increase overall nail health and prevent breakage, allowing nails to grow longer.
Biotin
Biotin, also known as vitamin B7, is found in many hair, skin, and nail vitamins. It is most concentrated in organ meats, such as liver, but can also be found in egg yolks, dairy products, yeast, salmon, avocado, sweet potato, nuts, seeds, and even cauliflower. Biotin deficiency is rare, but consuming it through food or supplements may help strengthen brittle nails and improve their growth. A 2007 study found that taking 2.5 milligrams of biotin daily reduced breakage and increased overall nail health.
Vitamin A
Vitamin A is essential for strong, healthy, and accelerated nail growth. Orange and yellow vegetables, such as carrots, sweet potatoes, bell peppers, and squash, are excellent sources of vitamin A.
Healthy Fats
Adding more nuts, seeds, and avocados to your diet can help your nails grow shinier and stronger. Healthy fats help supply the body with magnesium, which is essential for nail health.
Zinc
Zinc is required for the healthy growth of nails. Animal proteins are a great source of zinc, but it can also be found in certain plant foods.
Collagen-Boosting Supplements
Collagen-boosting supplements have been shown to increase nail strength and growth. In a study, almost all participants reported stronger nails and faster growth after two to three months of taking collagen-boosting capsules.
Selenium
Some people claim that rubbing garlic on nails or painting nails with garlic-infused clear nail polish helps their nails grow longer and stronger. While no research has confirmed this, garlic is high in selenium, and some studies have linked low selenium levels to weaker nails.
Protein
A protein deficiency can lead to weakened, slow-growing nails. However, unless you are protein-deficient, increasing your protein intake is unlikely to strengthen your nails.
In addition to these specific nutrients, maintaining a nutrient-rich diet with a variety of fruits, vegetables, nuts, and seeds, as well as adequate protein and omega-3 fatty acids, is likely the best way to achieve strong, shiny, and healthy nails.

Nail care
Nail growth is influenced by various factors, including genetics, overall health, age, exposure to injury or trauma, and the environment. While there are no scientifically proven methods to make nails grow faster, maintaining strong and healthy nails can help encourage growth. Here are some tips for nail care:
Nutrition
A balanced diet rich in essential nutrients like biotin, protein, and vitamins is crucial for promoting nail growth. Biotin, also known as vitamin B7, helps strengthen brittle nails and reduce breakage. It can be found in dietary supplements or vitamins for skin, hair, and nail health. However, it is important to consult a dermatologist or doctor before taking large doses of any supplement.
Keeping nails clean and well-maintained is essential for preventing breakage and encouraging growth. This includes regular filing and trimming to manage length and shape. When cutting nails, it is recommended to cut them straight across, slightly rounding the edges to avoid snags or tears. For toenails, keeping them short minimizes the risk of injury and trauma.
Cuticle Care
Cuticles are a vital part of nail health, as they protect the nail root from germs and bacteria. It is important to avoid pushing or cutting cuticles as this can lead to infection. Instead, apply cuticle oil daily to keep them moisturized and prevent dead skin from growing on the nails.
Environmental Factors
Environmental factors such as temperature and climate can affect nail growth. Warmer climates tend to promote faster nail growth due to increased blood circulation, which delivers essential nutrients to the nail matrix. In cold weather, wearing gloves or mittens can help protect nails from drying out and splitting due to exposure to detergents and dish soap.
Lifestyle Factors
Lifestyle factors, such as frequent hand use and certain occupations, can also influence nail growth. Jobs that involve constant hand movement, like typing or playing musical instruments, may stimulate nail growth. Additionally, nail-biting, using nails as tools, or picking at cuticles can slow down nail growth and lead to other nail problems.
While there may not be a magic solution to speeding up nail growth, following these nail care tips can help promote stronger and healthier nails, allowing them to grow longer and at their optimal rate.
