Several factors influence nail growth rates, which vary from person to person. Fingernails grow faster than toenails, with an average growth rate of 3.47-3.5 mm per month, while toenails grow at 1.62 mm per month. Nails on the dominant hand tend to grow faster, and nails also grow faster in warmer climates. Age, sex, diet, overall health, and medical conditions can all impact nail growth, with older adults experiencing slower nail growth than younger individuals. Immunocompromised individuals may also experience slower nail growth. Maintaining a balanced diet, practicing good nail hygiene, and keeping nails moisturized can promote healthy nail growth.

What You'll Learn
Toenails grow slower than fingernails
One theory suggests that the more frequent use of our fingers compared to our toes leads to faster nail growth in the fingers. This is supported by the observation that nails on the dominant hand, which is more often used, tend to grow faster. The increased use of the dominant hand also results in a higher risk of trauma, which further stimulates nail growth.
Another factor influencing the growth rate is proximity to the heart, the source of blood circulation. As the fingers are closer to the heart than the toes, it is believed that the nails on the fingers receive more blood circulation, contributing to their faster growth.
Additionally, toenails are generally subjected to less trauma than fingernails. While stubbing a toe can cause a temporary increase in circulation, it typically does not have a lasting impact on toenail growth. In contrast, injuries to fingernails, such as a subungual hematoma, can take two to three months to heal, whereas toenails can take up to nine months to recover from similar trauma.
It is worth noting that nail growth rates can be influenced by various factors, including age, sex, season, exercise level, diet, and hereditary factors. For example, nails grow faster during the summertime and in warmer climates, and men's nails typically grow faster than women's, except during pregnancy and old age. Maintaining good nail hygiene and addressing any nutritional deficiencies can also promote healthy nail growth.

Nails grow faster in the summer
Fingernails grow at an average rate of about a tenth of a millimeter per day, or about 3.47 millimeters per month. Toenails, on the other hand, grow much slower, at a rate of about 1.62 millimeters per month.
There are several factors that can affect the rate of nail growth, including age, sex, season, exercise level, diet, hereditary factors, and overall health. For example, nails tend to grow faster in the summer and slower in the winter. This may be due to the increase in temperature and circulation during the warmer months.
Additionally, the nails on your dominant hand tend to grow faster, as do the nails on your longer fingers. This could be because these nails are used more often and the body compensates by increasing the nail growth rate.
While there are no scientifically proven methods to make nails grow faster, you can increase the overall health of your nails by taking biotin supplements and maintaining good nail hygiene. This will help strengthen your nails and prevent them from breaking, allowing them to grow longer.
By understanding the factors that affect nail growth, you can optimize the conditions for healthy nail growth and maintain the length and shape of your nails.

Nail biting and trauma slow growth
Nail biting and trauma can slow nail growth, and in some cases, cause permanent cosmetic changes. Trauma to the nail can occur in many ways, from a blow to the nail to closing your finger in a door or drawer. Repeated trauma to toenails, caused by ill-fitting shoes, can lead to deformities in the nails. Nail biting is a form of trauma that can cause acute paronychia, a type of infection where bacteria get underneath the tissue at the side of the nail, causing swelling and irritation.
Nail biting can also increase the likelihood of developing common infections, such as a cold, by facilitating the transfer of bacteria from your hands to your mouth and nose. In addition, nail biting can contribute to infections in the surrounding areas of skin and nail bed. An infection of the nail bed, known as paronychia, may require medical attention.
Aside from the health risks, nail biting can also slow nail growth by damaging the nail matrix, which is the tissue inside the cuticle where new nails are formed. If the nail matrix is injured, a ridge or split can develop, and the nail may be malformed or cracked when it grows back. In severe cases, the nail may fail to regrow.
To promote healthy nail growth, it is important to practice good nail hygiene and address any underlying nutritional deficiencies or health conditions that may be affecting nail growth. While there are no scientifically proven methods to make nails grow faster, taking supplements such as biotin, vitamin C, vitamin E, iron, zinc, and calcium can promote healthy nail growth. Keeping your nails trimmed and avoiding nail biting or cuticle picking can also help prevent trauma and slow nail growth.

Age, hormones, and health influence growth
Age, hormones, and overall health are key factors influencing nail growth. Fingernails grow at an average rate of 3.47mm per month, or about a tenth of a millimeter per day. Toenails grow slower, at around 1.6mm per month. However, these rates vary from person to person and are influenced by age, hormones, and health.
Age plays a role in nail growth, as blood circulation slows with age, affecting the speed of nail growth. A 2007 study found that the growth rate of a thumbnail decreased from 0.123mm per day at age 23 to 0.095mm per day at age 67.
Hormone levels also impact nail growth rates. For example, pregnancy can cause rapid nail growth, while lactation may decrease nail growth. Puberty is another period of fluctuating hormones, with nail growth peaking during this time and declining as hormone levels balance out with age. The menopausal transition, characterised by changing hormone levels, can also affect nail health, with some women experiencing menopause brittle nails.
Overall health and nutrition are crucial factors in nail growth. Nutritional deficiencies, such as vitamin B12 or iron deficiency, can cause changes in nail appearance, such as spoon nails or discolouration. Chronic conditions, such as inflammatory skin diseases, hypo- or hyperthyroidism, or autoimmune disorders, may also impact nail health. Additionally, environmental factors like temperature and climate can influence nail growth, with warmer climates promoting faster nail growth.
While some factors influencing nail growth are beyond our control, maintaining good nail hygiene and a healthy diet can help support nail health and growth.

Good nail hygiene promotes growth
Good nail hygiene is essential for promoting nail growth and maintaining overall nail health. Nails grow at different rates, influenced by factors such as hand dominance, season, age, hormone levels, and overall health. While some of these factors are beyond our control, adopting good nail hygiene practices can significantly impact nail growth and overall nail health.
One crucial aspect of nail hygiene is keeping nails clean and dry. Bacteria and fungi thrive in moist environments, so maintaining clean and dry nails helps prevent bacterial growth. Scrubbing the underside of the nails with soap and water or using a nail brush during handwashing is an effective way to ensure proper nail hygiene. Additionally, it is recommended to cut nails straight across using sharp nail scissors or clippers and then slightly round the tips for enhanced strength.
Protecting nails from water exposure is another important consideration. Excessive water exposure can weaken nails, leading to splitting, peeling, or breaking. Wearing gloves while performing tasks like cleaning or washing dishes can help minimize water contact. It is also beneficial to moisturize the hands after washing them.
Nail biting, using nails as tools, or picking at cuticles should be avoided as these habits can slow nail growth and cause various nail problems. Instead of biting, it is advisable to clip hangnails with clean and sanitized nail trimmers. Regular nail trimming is essential, especially for toenails, as it helps minimize the risk of trauma and injury.
Good nail hygiene also extends to properly caring for nail grooming tools. It is important to clean and sanitize items such as nail clippers and files before each use to prevent the spread of germs and potential nail infections. Additionally, maintaining overall hand and nail cleanliness by washing hands regularly and keeping nails short can help prevent the spread of certain infections.
