What You'll Learn
Toenails grow slower than fingernails
There are a number of factors that affect how fast your nails grow. Fingernails grow faster in the summer, and nails on the dominant hand tend to grow faster than nails on the non-dominant hand. Nails on the longest fingers also tend to grow faster. This is because fingers receive more blood flow because they are used more often, which likely contributes to faster fingernail growth.
Age, nutrition, and season are also major determinants of nail growth, with slower growth in older people, those who are malnourished, or those in cold climates. Nail growth can also slow down if you are sick or immunocompromised. However, during pregnancy, your nails might grow faster due to hormonal changes.
There are no scientifically proven methods to make nails grow faster, but there are ways to increase nail health and prevent them from breaking. Taking biotin supplements, for example, may improve the firmness, thickness, and hardness of nails.

Toenails grow at 1.62mm per month
Toenails grow at an average rate of 1.62mm per month, about three times slower than fingernails. This rate can vary from person to person, influenced by various factors such as genetics, overall health, age, nutritional deficiencies, and underlying health conditions. For example, younger individuals typically experience faster nail growth compared to older adults, and nails tend to grow slower in older adults and colder climates.
The exact mechanisms that control the speed of toenail and fingernail growth are unknown, but several theories attempt to explain the difference in growth rates between the two. One theory suggests that the more frequent use of our fingers leads to faster nail growth, as the body compensates for constant use. Another theory posits that nail growth rate is higher in fingers due to their proximity to the heart, resulting in increased blood circulation. Additionally, trauma or injury can increase the rate of nail regrowth due to increased blood flow to the affected area.
Practicing good nail hygiene and taking care of your overall health can positively impact nail growth. Maintaining a balanced diet rich in essential nutrients like biotin, protein, vitamins, and minerals is crucial for promoting healthy nail growth. Nails may grow slower if you are sick or malnourished, and hormonal changes during pregnancy can also affect nail growth rates.
While there are no scientifically proven methods to accelerate nail growth, you can improve the overall health and strength of your nails. Taking biotin supplements, for instance, promotes cell growth and helps your body metabolize protein-building amino acids, contributing to faster nail growth. Massaging the toenail and nail bed, keeping them clean and dry, and allowing them to breathe by wearing open-toe shoes are other ways to encourage nail growth and maintain their health.

Fingernails grow faster in summer
Fingernails and toenails grow at different rates, with toenails taking longer to regrow. On average, it can take up to 18 months for a toenail to completely regrow, compared to about 4 to 6 months for a fingernail. The reason for this discrepancy is not fully understood, but one theory suggests that it is due to the higher blood flow in the fingers since they are used more frequently.
Various factors influence nail growth rates, including age, gender, and seasonal changes. Interestingly, fingernails grow faster in the summer, and this is attributed to increased vitamin D exposure from sunlight and a higher consumption of fruits and vegetables during this season. The boost in vitamin D levels contributes to accelerated nail growth.
In addition to vitamin intake, blood flow also plays a role in nail growth. Higher body temperatures and increased circulation, which can occur during warmer months, lead to faster fingernail growth. This may explain why nails, including both fingernails and toenails, tend to grow more in the summer.
While the growth rate can vary among individuals, the standard rate of growth for a normal fingernail is between 0.5 and 1.2 mm per week, translating to approximately 0.1 mm per day. In contrast, toenails grow much slower, with an average growth rate of 1.62 mm per month.
Practicing good nail hygiene and maintaining a well-balanced diet can help support healthy nail growth. Additionally, taking biotin supplements can promote cell growth and contribute to faster nail growth by aiding in the metabolism of protein-building amino acids.

Toenails take 12-18 months to regrow
Toenails grow at an average rate of 1.62 mm per month, which is about three times slower than fingernails. This means that toenails take longer to regrow than fingernails. On average, it takes anywhere from 12 to 18 months for a toenail to completely regrow, while a fingernail takes about 4 to 6 months.
The rate of toenail regrowth can vary from person to person and can be influenced by various factors. These factors include age, health, individual biology, and certain circumstances such as trauma or injury. For example, toenails may fall off or become damaged due to stubbing your toe, dropping something heavy on your foot, or wearing ill-fitting shoes. In such cases, the regrowth process can take anywhere from 6 months to 2 years.
To speed up the regrowth process, it is recommended to practice good nail hygiene and keep the toenail area clean, dry, and protected. Applying olive oil or vaseline may also help accelerate regrowth. Additionally, taking biotin supplements can promote cell growth and contribute to faster nail growth.
It is important to note that nails grow from underneath the skin at the matrix, which is the root of the nail. New cells form in the matrix, and as these new cells grow, older cells move up and push through the skin. This process of nail growth can be slower in older adults, during illness or malnutrition, and in colder climates. On the other hand, nails tend to grow faster in the summer and on the dominant hand.

Toenail growth slows with age
Toenails grow at an average rate of 1.62 mm per month, which is significantly slower than the growth rate of fingernails. Toenails take longer to regrow, with the process taking anywhere from 12 to 18 months. In comparison, fingernails typically take 4 to 6 months to regrow.
Several factors influence the rate of toenail growth, including age, sex, season, exercise level, diet, and hereditary factors. One of the critical factors affecting toenail growth is age. As people get older, their toenails tend to grow slower. Bruce Robinson, a clinical instructor of dermatology, noted that nail growth reaches its peak during the second and third decades of life, with a slight decline in growth rate thereafter. This decline in growth rate with age may be attributed to decreased blood flow and medical conditions that can affect circulation, such as Raynaud's phenomenon.
The exact mechanisms behind the varying growth rates of fingernails and toenails with age are not fully understood. However, it is speculated that the slower growth of toenails in older adults could be related to the reduced blood flow associated with aging. As blood circulation decreases with age, it may impact the rate at which toenails grow. Additionally, older adults may experience a decline in overall health, which can also contribute to slower nail growth.
Good nail hygiene practices and a balanced diet rich in essential nutrients can help support healthy toenail growth. Biotin supplements, vitamin C, vitamin E, iron, zinc, and calcium are recommended to promote nail growth and overall nail health. It is also important to protect the toenails from trauma and injury, as these can further slow down the regrowth process.
While toenail growth may slow down with age, maintaining overall health and practicing proper nail care can help support optimal toenail growth and health as people age.
