Fingernails grow faster than toenails, and the nails on your dominant hand grow faster than the rest, as do the nails on your longer fingers. This is due to an increased likelihood of trauma to the nails on your dominant hand, which increases blood flow and nutrient delivery to the area. Additionally, frequent nail clipping and biting can stimulate nail growth, as can taking biotin supplements and using nail hardeners.

What You'll Learn
The dominant hand's nails grow faster
The rate at which fingernails grow is influenced by a variety of factors, including genetics, nutrition, circulation, and trauma. Nails grow from the nail matrix, the pale, half-moon-shaped section at the base of the nail hidden under the cuticle.
The nails on the dominant hand are said to grow faster, supported by both scientific studies and several personal accounts. This is likely because the dominant hand is used more frequently, increasing the risk of trauma to the nails. When trauma occurs, the body sends more blood and nutrients to the affected area to aid in repair, stimulating nail growth.
The correlation between nail growth and trauma was explored by dermatologist Rodney Dawber, who conducted an experiment after injuring his left ring finger. He hypothesized that the nail on his splinted finger would grow slower due to reduced fingertip use. Indeed, his left ring fingernail grew 25% slower during the three months it was splinted compared to the subsequent three months after the splint was removed.
Additionally, frequent nail clipping and biting have been associated with faster nail growth. Nail biting, or onychophagia, can cause trauma to the nail, stimulating circulation in the nail bed. Regular nail clipping is a safer alternative to achieve faster nail growth without the same risks associated with nail biting.
While there are no scientifically proven methods to accelerate nail growth, maintaining overall health and proper nail care can strengthen nails and prevent breakage, allowing them to grow longer. Taking biotin, for example, has been shown to reduce breakage and improve nail health. Proper nail care includes keeping nails clean and well-groomed to prevent the accumulation of dirt, bacteria, and fungi that can lead to infections.

Trauma stimulates nail growth
Nail trauma can lead to changes in nail growth, including temporary or long-term alterations in their shape, texture, and colour. These changes can be observed in the form of thickening, ridging, discoloration, or a rough texture. Trauma can interfere with the production of healthy cells, causing the nail to grow unevenly or distortedly. In some cases, the nail may grow more slowly or even stop growing temporarily as it recovers from the injury.
The risk of nail trauma is higher on the dominant hand, as it is used more frequently. This increased use results in greater blood circulation in the fingertips of the dominant hand, contributing to faster nail growth. Trauma can occur through various everyday activities, such as catching your nail on something, hitting it with a hammer, or closing your finger in a door or drawer. Nail biting and cuticle biting are also common habits that can cause trauma to the nails.
To promote nail health and reduce the risk of trauma, it is important to keep your nails trimmed and avoid biting them or their cuticles. Wearing protective gloves during repetitive tasks or heavy lifting can provide additional protection against nail injuries.
While minor nail traumas may heal without intervention, keeping the affected area clean can aid in recovery. For more severe cases, it is recommended to seek help from a board-certified dermatologist. They can advise on the best course of treatment, which may include trimming damaged sections or draining blood that has accumulated under the nail.
In summary, trauma stimulates nail growth by increasing blood circulation in the affected area and disrupting the normal growth cycle. This can lead to changes in the speed and quality of nail growth, with potential temporary or long-term alterations in shape, texture, and colour. Protecting nails from trauma and seeking appropriate treatment are important for maintaining nail health.

Fingernails grow faster than toenails
Additionally, it is believed that the growth rate of nails is influenced by how often a fingertip is used. This is supported by the observation that people who type a lot have faster-growing nails on their dominant hand. Furthermore, nail-biting and frequent nail clipping are associated with faster nail growth, possibly due to the stimulation of circulation in the nail bed caused by biting or clipping.
While there may be variations in growth rates between different fingers and individuals, the consensus is that fingernails generally outpace toenails in growth. Genetics, nutrient deficiencies, and overall health also play a role in nail growth rates and strength. Proper nail care, including the use of biotin, nail hardeners, and avoiding toxic polishes, can help improve nail health and prevent breakage.

Nail growth peaks during puberty
Several factors influence nail growth, including age, hand dominance, finger length, season, and overall health. One of the most significant factors is age, with nail growth typically peaking during puberty and gradually declining as individuals age.
Puberty is a time of fluctuating hormone levels, which contribute to faster nail growth. As hormone levels stabilise with age, nail growth tends to slow down. By the age of 20, the growth rate slows by approximately 0.5% per year, and nails may undergo changes in appearance and texture.
The nails on the dominant hand also tend to grow faster, as they are more prone to trauma and injury due to frequent use. This increased risk of trauma stimulates circulation in the nail bed, promoting faster nail growth. Similarly, nails on longer fingers may experience faster growth for the same reason.
While there are no scientifically proven methods to accelerate nail growth, maintaining overall health, proper hydration, and a balanced diet can positively impact nail health and strength. Additionally, protecting nails from damage and practising proper nail care can help optimise their growth and prevent breakage.
In summary, nail growth is at its peak during puberty due to fluctuating hormone levels. As individuals age, hormone levels stabilise, leading to a gradual decline in nail growth. The dominant hand and longer fingers may exhibit faster nail growth due to increased circulation and trauma associated with frequent use. Maintaining overall health and proper nail care are key to supporting nail growth and strength.

Nail biting can increase growth rate
It is true that nail-biting can increase nail growth rates. Onychophagia, or the chronic habit of biting one's nails, has been associated with faster nail growth. While the exact mechanism is unclear, researchers propose that nail biting stimulates the growth plate of each finger, increasing metabolic activity and resulting in quicker nail formation. Additionally, nail biting can be considered a form of trauma to the nail, which increases circulation in the nail bed and promotes nail growth.
Nail growth is influenced by various factors, including age, medication, diseases, nutritional status, injuries, temperature changes, and genetics. For instance, nails tend to grow faster during the summer due to increased circulation at the fingertips. Similarly, the nails on the dominant hand typically grow faster because it is used more often, leading to a higher risk of trauma and subsequent increased blood flow to the area.
To promote nail health and stronger nails, it is recommended to take biotin supplements, use nail hardeners sparingly, and avoid glue-on nails and toxic nail polishes. Maintaining good nail hygiene, such as regular trimming, cuticle care, and moisturization, is also essential for overall nail health.
While nail biting may lead to faster nail growth, it is important to consider the potential negative consequences. Nail biting can contribute to infections in the surrounding skin and nail bed, such as paronychia. Additionally, it can increase the likelihood of transferring bacteria from the hands to the mouth and nose, potentially leading to common infections like the cold. In some cases, compulsive nail biting may be indicative of underlying anxiety, stress, or obsessive-compulsive disorder. Therefore, while nail biting may stimulate nail growth, it is important to weigh the potential risks and consider alternative methods to promote nail health and growth.
Quitting nail biting can lead to healthier nails and nail beds. Former nail biters have shared their experiences and strategies for growing out their nails and recovering their nail beds. Some recommend keeping the white part of the nail short to prevent breakage and avoid the temptation to bite. Others suggest avoiding detaching the nail bed by refraining from picking at the nails or getting things underneath them. Regular nail painting can also provide protection and strength, reducing nail flexibility and bending. It is important to note that recovering from nail biting and growing out nail beds takes time, and individuals should be patient during the process.
