Fingernails grow at an average rate of about 0.1 mm per day or 3.47 mm per month. Toenails, on the other hand, grow at a slower rate of about 1.62 mm per month. Several factors influence the rate of nail growth, including age, hormones, overall health, nutrition, and the use of the dominant hand. While there is no magic formula to accelerate nail growth, maintaining strong and healthy nails through proper nail care, a balanced diet, and good hygiene can promote optimal growth rates.

Fingernails grow at an average rate of 3.47mm per month
Pregnancy can also cause an increase in nail growth due to hormonal changes, while lactation may have the opposite effect. The speed of nail growth can also be influenced by the season, with nails typically growing faster during the warmer months. However, this difference is usually quite subtle.
While there is no magic formula to accelerate nail growth, maintaining strong and healthy nails is essential. Proper nail care, such as regular trimming, cuticle care, and moisturization, can help support nail growth. Additionally, a well-balanced diet that includes protein, water, fruits, vegetables, vitamins, and minerals is crucial for healthy nails.
Certain dietary supplements, like biotin, have been found to improve nail health and reduce breakage. Moisturizing the hands and nails is another way to promote nail growth, as dry skin can lead to fungal and bacterial infections that impact nail health. Overall, focusing on limiting damage to your nails is more effective than solely aiming for faster growth.

While there is no magic formula to accelerate nail growth, maintaining strong and healthy nails is essential. Proper nail care and hygiene practices can help promote nail growth and overall nail health. This includes cutting nails straight across, rounding the edges, and ensuring there are no snags or tears. Keeping toenails trimmed can help minimise the risk of injury and trauma. Additionally, moisturising the hands and nails can be beneficial, as dry skin can lead to nail damage and increase the risk of fungal and bacterial infections.
A well-balanced diet that includes protein, water, fruits, vegetables, and essential vitamins and minerals is crucial for healthy nail growth. Nutritional deficiencies can impact nail health, so ensuring adequate nutrient intake is vital. Certain supplements, such as biotin, have been found to reduce nail breakage and improve overall nail health. However, it is always advisable to consult with a healthcare professional before starting any supplements.
While bitten nails may grow at a faster rate due to increased circulation in the nail bed, it is important to note that biting can damage the nails and lead to potential infections. Therefore, it is recommended to focus on limiting damage and maintaining overall nail health rather than solely aiming for faster growth. Regular nail grooming, such as keeping nails clean and trimmed, is essential for nail health. If nails are growing unusually slowly or displaying any unusual symptoms, it is recommended to seek advice from a healthcare professional to rule out any underlying conditions or nutritional deficiencies.

Nails on the dominant hand grow faster
On average, fingernails grow at a rate of about 3.47 millimetres per month or about a tenth of a millimetre per day. However, this rate can vary due to several factors, including age, sex, season, exercise level, diet, hereditary factors, and overall health. For example, nails tend to grow faster during the day and in the summer. Additionally, the rate of growth also depends on which hand and finger the nail is on.
Interestingly, it has been observed that the nails on the dominant hand tend to grow faster. This can be attributed to the increased use of the dominant hand, which leads to a higher risk of trauma, such as catching your nail on something or hitting it. When trauma occurs, the body naturally sends more blood and nutrients to the area to aid in repair, and this increased nutrient supply may contribute to accelerated nail growth.
The correlation between dominant hand use and faster nail growth is supported by anecdotal evidence. Some individuals have shared their experiences, noting that their dominant hand's nails seem to grow at a quicker pace. This observation aligns with the theory that increased hand usage stimulates nail growth.
While there is no magic formula for speeding up nail growth, maintaining strong and healthy nails is always beneficial. Proper nail care, such as regular trimming, moisturising, and cuticle maintenance, can contribute to overall nail health. Additionally, certain supplements like biotin have been found to enhance nail health and reduce breakage.
In summary, while nails on the dominant hand may grow faster due to increased usage and nutrient supply, promoting overall nail health through proper care and nutrition is essential for supporting nail growth and maintaining strong, healthy nails.

Nail growth slows with age
Fingernails grow, on average, about a tenth of a millimeter per day, or around three millimeters per month. However, there are several factors that can influence this rate of growth, including age, hand dominance, finger length, season, and overall health. While there is no magic formula for nail growth, maintaining strong and healthy nails can help encourage faster growth.
As we age, our bodies undergo various changes, and nail growth is no exception. The rate of nail growth slows down, and nails may become dull, brittle, and prone to fragmentation. This change in speed is likely due to the decrease in blood circulation that occurs with aging. For example, 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.
In addition to slower growth, nails may also exhibit changes in texture, thickness, color, and shape as we age. The curve of the nails may become more rounded, a condition known as clubbing, which can indicate long-term oxygen deprivation and underlying health issues. Nails, especially toenails, may thicken and become more susceptible to ingrown toenails, which can cause substantial pain and walking difficulties in older individuals.
The color of nails may also change with age, often turning yellow, gray, pale, or opaque. While some discoloration may be attributed to fungal infections, dark stripes or ridges on the nails could indicate a more serious condition, such as melanoma or skin cancer. It is important to consult a healthcare provider if you notice significant changes in your nails, as they can help determine if these changes are normal signs of aging or indicative of underlying health issues.
While nail growth slows with age, proper nail care and hygiene can help maintain strong and healthy nails. Trimming nails regularly, moisturizing, and using cuticle oil can help promote nail health and encourage growth. Additionally, addressing any nutritional deficiencies and maintaining a well-balanced diet can support overall nail health and growth.

Hormones, health conditions and nutrition affect nail growth
On average, fingernails grow about a tenth of a millimetre per day, but this can be affected by factors such as age, hormone levels, and overall health. For instance, blood circulation slows with age, which may cause slower nail growth.
Hormones
Hormones play a significant role in nail growth and health. For example, during pregnancy, when oestrogen and progesterone levels are at their highest, many women experience rapid nail growth. Conversely, lower oestrogen levels can lead to dull, yellowish nails, and women experiencing menopause or postpartum may notice changes in their nails due to hormonal shifts. Additionally, androgen hormones like testosterone influence hair growth, and imbalances can lead to hair loss and unwanted body hair.
Health Conditions
Certain health conditions and nutrient deficiencies can impact nail growth and appearance. For example, iron deficiency can cause nail abnormalities, such as concave-shaped nails, while a lack of magnesium can result in vertical ridges. Skin diseases like psoriasis, eczema, lichen planus, and lupus can also affect the nails, causing pits, grooves, or crumbling. Discolouration, thickening, and brittle nails are common with ageing, but any abnormal changes should be medically investigated as they may indicate underlying health issues.
Nutrition
Nutrition plays a crucial role in nail health. A nutrient-rich diet is essential for strong and healthy nails. Deficiencies in specific vitamins and minerals, such as biotin, zinc, vitamin B12, and folate, can negatively affect nail health and growth. Consuming a balanced diet that includes animal proteins, whole grains, dark leafy greens, nuts, and beans can provide the necessary nutrients for nail growth and strength. Additionally, taking biotin supplements has been shown to reduce nail breakage and improve overall nail health.
