Fingernails are constantly growing at a rate of about 0.1 millimetres per day, or 3.47 millimetres per month. This growth rate varies from person to person and can be influenced by factors such as age, gender, season, exercise, diet, and genetics. For example, nails tend to grow faster during the summer and on the dominant hand, especially the longer fingers. Toenails, on the other hand, grow at a slower rate, typically taking up to a year and a half to fully regrow if lost. While there is no magic solution to speed up nail growth, maintaining strong and healthy nails through proper nail care and a nutritious diet can help encourage growth.

What You'll Learn
Fingernails grow at 3.47mm per month on average, and toenails at 1.62mm
On average, fingernails grow at a rate of 3.47mm per month, while toenails grow at a slower rate of 1.62mm per month. This equates to about 0.1mm or 0.7mm of growth per day for fingernails and toenails, respectively.
Several factors influence the rate of nail growth, including age, health, and seasonality. Children and teenagers tend to have faster-growing nails than adults, with growth rates slowing down after puberty. Pregnant women also experience accelerated nail growth due to increased hormones, metabolism, and circulation.
Nail growth is also impacted by overall health and nutrition. Certain medical conditions, such as immunocompromised states, paralysis, malnutrition, infections, and specific drug therapies, can slow down nail growth. Additionally, nails tend to grow faster during the warmer months, possibly due to increased Vitamin D absorption from sun exposure.
The rate at which nails grow can vary slightly from person to person, and it is worth noting that nails on the dominant hand and longer fingers tend to grow faster. On average, it takes about four to six months for a fingernail to regrow completely, while toenails can take up to 12 to 18 months.

Nails on your dominant hand grow faster
Fingernails grow at an average rate of about three millimetres per month, while toenails grow at about one-third of that rate, or one millimetre per month. The rate of growth decreases by about 0.5% per year after the age of 25.
Several factors affect the rate of nail growth. For instance, nails on the dominant hand tend to grow faster, as do nails on the longer fingers. This is because the dominant hand is used more often, leading to increased blood circulation in that hand's fingertips. Similarly, nails grow faster during the day and in the summer.
Nail growth is also influenced by age, sex, exercise level, diet, hereditary factors, and seasonal changes. For example, nail growth peaks during puberty and gradually declines as hormone levels stabilise with age. Certain conditions, such as diabetes or circulatory issues, can impact nail growth and increase the risk of nail disorders.
Trauma to the nail, such as biting or clipping, can stimulate circulation in the nail bed and lead to faster nail growth. However, nail biting can pose risks, while regular nail clipping is generally safer and can still promote growth. Maintaining good nail hygiene and overall health can also contribute to stronger and healthier nails.

Nail growth is impacted by age, gender, and health
Fingernails grow at an average rate of around 3mm per month, with toenails growing about a third to half as quickly. However, nail growth is impacted by several factors, including age, gender, and health. Starting at age 25, the rate of nail growth decreases by approximately 0.5% per year. Additionally, nails may become thicker or thinner with age, and conditions like psoriasis and rheumatoid arthritis can contribute to thicker nails.
Ageing nails can exhibit changes in growth rate, texture, thickness, shape, and colour. For example, longitudinal melanonychia, characterised by dark stripes or ridges along the length of the nail, is more common in darker-skinned individuals as they age. Nails may also become more brittle and prone to breaking with age, exacerbated by repeated wetting and drying or exposure to harsh chemicals.
Gender also plays a role in nail growth, with nails growing faster on larger fingers and during the summer and daytime. Right-handed individuals tend to have faster nail growth on their right hand, while the opposite is true for left-handed people.
Nail growth is also influenced by overall health and nutritional status. Internal processes, nutritional deficiencies, and external factors like long-term exposure to chemicals or ultraviolet light can impact nail growth over time. Certain medical conditions, such as heart and lung disease, anemia, liver and kidney problems, and diabetes, can manifest as changes in the texture, thickness, colour, or shape of nails.
Fungal infections, common in older adults, can cause nail thickening and discolouration. Toenails are particularly susceptible due to the warm, moist environment created by shoes. Therefore, maintaining strong and healthy nails is crucial for encouraging optimal nail growth. Proper nail care, including cutting nails straight and rounding the edges, can help prevent snags and tears, while avoiding cuticle trimming can lower the risk of bacterial infections.

Frequent nail clipping makes nails grow faster
While there are no scientifically proven methods to make nails grow faster, frequent nail clipping can help maintain their length and prevent them from becoming overly long and fragile. Regular nail trimming also helps to give the illusion of faster growth.
Nail growth is influenced by various factors, including genetics, overall health, age, nutrition, blood circulation, hormones, exposure to injury or trauma, and the environment. For example, younger people tend to experience faster nail growth than older adults, and nails grow faster during the day and in warmer climates.
To promote nail health and support faster nail growth, it is important to take care of your body and maintain a well-balanced lifestyle. This includes having a balanced diet rich in essential nutrients like biotin, protein, and vitamins A, D, E, and C, as well as minerals like zinc, iron, and calcium. Additionally, keeping your nails clean, moisturized, and well-maintained can prevent breakage and allow them to grow longer.
It is worth noting that there are some misconceptions about nail growth. For instance, while special treatments, products, or home remedies are claimed to accelerate nail growth, there is little evidence to support their effectiveness. Instead, the key to achieving faster-growing nails is to focus on limiting damage and maintaining overall nail health.
In conclusion, while frequent nail clipping alone may not significantly increase nail growth rate, combining it with proper nail care practices, a well-balanced diet, and a healthy lifestyle can contribute to stronger and healthier nails that are less prone to breakage and can grow longer.

Nails grow faster in the summer
It's a well-known fact that nails grow faster in the summer. While there is no definitive scientific explanation for this phenomenon, several factors may contribute to it.
Firstly, it is believed that the increase in temperature during the summer months stimulates nail growth. This is supported by the observation that nails tend to grow faster in hotter countries or regions. The warmth may increase blood circulation in the body, including the hands and feet, providing more nutrients to the nails and promoting their growth.
Secondly, summer activities and lifestyle changes can play a role. People tend to be more active during the summer, engaging in outdoor pursuits and water-based activities, which can stimulate nail growth. The increased exposure to sunlight and higher vitamin D levels can also contribute to overall health, including nail health, leading to stronger and possibly faster-growing nails.
Additionally, it is worth noting that nails on the dominant hand, typically the hand we use the most, tend to grow faster. This is because the dominant hand is more prone to trauma, such as catching or hitting your nails, which increases blood flow and nutrient delivery to the area, promoting repair and growth. During summer, people are generally more active and tend to use their hands more, especially when participating in outdoor activities, which could contribute to faster nail growth on the dominant hand.
While the exact mechanism behind faster nail growth in the summer is not fully understood, a combination of environmental and lifestyle factors is likely at play. It is important to note that while nails may grow faster during this season, maintaining healthy nails is also influenced by factors such as diet, medical conditions, and proper nail care. Taking care of your nails and providing them with the necessary nutrients will help keep them strong and promote optimal growth, regardless of the season.
