Your nails are more than just a canvas for nail art or a tool for scratching an itch. They protect your fingers and toes from injuries and help you grip, pick up, and feel objects. On average, fingernails grow about 3.47 millimeters a month or about a tenth of a millimeter per day. However, this growth rate can vary depending on factors such as age, hormone levels, overall health, and even the finger on which the nail is located. For instance, the nails on your dominant hand and longer fingers tend to grow faster, and a 2007 study found that the little finger's nail grows slower than the others. So, do nails grow every day, and is there a difference in growth rate between the pointer finger and other digits?

Factors affecting nail growth include hand, finger, age, hormones, and health
Fingernails grow on average about a tenth of a millimeter per day, but this rate can vary due to several factors. Nails on the dominant hand tend to grow faster, possibly due to increased usage, which may lead to more trauma and subsequent repair. Longer fingers also tend to have faster-growing nails. Additionally, the little finger's nail typically grows slower than other fingernails.
Age plays a significant role in nail growth, with older individuals experiencing slower growth rates due to reduced blood circulation. Hormone levels also influence nail growth, with pregnancy and puberty being associated with increased nail growth. However, during lactation, nail growth may decrease. Overall health and nutrient deficiencies can also impact nail growth and appearance. Certain conditions, such as diabetes and circulatory issues, warrant close monitoring of nail health.
Nail-biting, or onychophagia, has been linked to faster nail growth, possibly due to the trauma caused, which stimulates circulation in the nail bed. Frequent nail clipping may also contribute to slightly faster nail growth without the same risks as nail-biting. Toenails grow much slower than fingernails, taking up to a year and a half to fully regrow if lost.
Nail health is an important aspect of personal care, and certain disorders can affect nail growth and appearance. Onychomycosis, a fungal infection, is the most common nail disease, affecting 10-20% of adults, especially the elderly. Brittle nail disorder, characterized by increased nail fragility, is also prevalent, impacting around 20% of the population, with a higher incidence in women and older individuals. Proper nail care and monitoring are essential to maintaining nail health and identifying any potential issues.

Trauma to the nail can cause a temporary burst of circulation, speeding up nail growth
Fingernails grow at an average rate of about a tenth of a millimeter per day, but various factors can affect this rate of growth, including which finger the nail is on, your age, hormone levels, and overall health. For instance, the nails on your dominant hand grow faster than the rest, as do the nails on your longer fingers.
The severity of the injury determines the treatment required. Minor trauma may heal without intervention, but keeping the area clean can promote recovery. For significant changes or pain, it is recommended to seek help from a dermatologist. Severe cases might require draining blood from under the nail or even surgical procedures. While the nail may eventually return to its original appearance, profound matrix damage could necessitate ongoing care or reconstructive approaches.
To protect your nails from trauma, consider wearing protective gloves during repetitive tasks or heavy lifting. Keeping your nails trimmed and maintained also minimizes the chance of breakage.

Nails grow at 0.1 mm per day on average, but this varies across individuals
On average, fingernails grow at a rate of about 0.1 mm per day, or approximately 3.47 mm per month. This equates to about one-tenth of a millimeter each day. However, it's important to note that this growth rate can vary across individuals and even between different fingers on the same person. The nails on your dominant hand, for instance, tend to grow faster than those on your non-dominant hand. Similarly, the nails on your longer fingers, such as the pointer finger, typically grow more quickly than those on your little finger.
Several factors influence the rate of nail growth. Age is one of them; as you get older, your nail growth rate tends to slow down. This may be attributed to a decrease in blood circulation as you age. Hormone levels also play a role, with nail growth rates fluctuating during different stages of life, such as puberty and pregnancy. Overall health and nutrient deficiencies can also impact nail growth. For example, a fever, injury, chemotherapy, or significant stress can cause nails to grow slowly or even stop growing temporarily.
To promote healthy nail growth, it is essential to maintain overall health and practice good nail care habits. Eating a nutritious, well-balanced diet and ensuring adequate nail hygiene can support nail health and growth. While there are no scientifically proven methods to accelerate nail growth, frequent nail clipping can help them grow a little faster and is safer than nail-biting.
It's worth noting that toenails grow much slower than fingernails, with an average growth rate of 1.62 mm per month. If you lose a toenail, it can take up to a year and a half to fully regrow, whereas a fingernail typically takes about six months to regrow. Toenails are generally slower to regrow because they are less prone to trauma and have lower blood circulation than fingers.

Toenails grow at a slower rate than fingernails, taking 12-18 months to regrow
Fingernails grow at an average rate of 3.47 mm per month or about a tenth of a millimeter per day. The specific growth rate depends on factors such as age, nutrition, season, gender, and overall health. For instance, the nails on your dominant hand or longer fingers tend to grow faster, and nail growth is typically faster during the day and in the summer.
Toenails, on the other hand, grow at a much slower rate of 1.62 mm per month. This means that if you lose a toenail, it can take up to 12-18 months for it to completely grow back, which is three times longer than the regrowth period for a fingernail.
The difference in growth rate between fingernails and toenails is attributed to their different uses and the resulting trauma to the nail bed. Our fingers are constantly in use, and any trauma or injury to the nail bed leads to increased blood flow and nutrient supply to the area, promoting faster nail growth. In contrast, our toes are generally less active and protected by socks and shoes, resulting in less trauma to the toenail bed and, consequently, slower nail growth.
While there are no scientifically proven methods to accelerate toenail growth, maintaining overall nail health is beneficial. For example, taking biotin supplements has been shown to reduce nail breakage and enhance nail health. Additionally, regular toenail clipping can promote slightly faster growth without the same risks associated with nail biting.

Nail appearance can indicate nutrient deficiencies and overall health
Our nails can be a window into our overall health and nutrient deficiencies. While nail issues often occur due to injury or overexposure to moisture, they can sometimes indicate underlying health issues. Dr. Sara Norris, a naturopathic doctor, explains that "for the general population, nail health is most often an indicator of poor nutritional intake or poor digestion".
Nails that are brittle, weak, and peeling can be a sign of a poor diet or, in rarer cases, a systemic disease. A lack of zinc can cause scattered white spots on the nails, which usually start to appear around middle school. Small white spots on the nail bed (punctate leukonychia) can be caused by a deficiency of calcium, zinc, and B vitamins. White longitudinal bands (longitudinal leukonychia) and horizontal lines (transverse leukonychia) can also be caused by these deficiencies.
Spoon-shaped nails, where the nail curves downward and looks round at the edges, can be a sign of iodine deficiency. However, nail clubbing can also indicate more serious health issues, such as lung and heart problems. Anemia, or iron deficiency, is the most common cause of a pale nail bed. Soft and thin nails can be a sign of kwashiorkor, a nutritional syndrome caused by severe protein malnutrition and relative carbohydrate excess. This can lead to retardation of skeletal and mental development, muscular wasting, and fatty liver.
While nail issues can sometimes indicate nutrient deficiencies or underlying health issues, it is important to remember that nail issues often occur due to injury, overexposure to moisture, or anxiety. Dr. Mark Benor, a clinical assistant professor of family medicine, reassures people that "nail issues usually don't bespeak a serious underlying illness". If you are concerned about your nail health, it is always best to consult a healthcare professional.
