A person's nails grow at different rates depending on various factors, including age, sex, season, exercise level, diet, and hereditary factors. Nails grow faster in children and young teens than in adults, with growth peaking during puberty and slowing down as hormone levels balance out with age. The nails on the dominant hand and the longer fingers tend to grow faster, and nails also grow faster during the day and in warmer months. While there are no scientifically proven methods to accelerate nail growth, maintaining good nail hygiene, taking biotin supplements, and using nail hardeners can help strengthen nails and prevent breakage.

What You'll Learn
Nail growth slows after puberty
While there are many factors that affect how fast your nails grow, age is one of the most significant. Nails grow faster as a child than as an adult, with children and young teens experiencing quicker nail growth and recovery. This is because nail growth slows down after puberty, when growth slows to about 50% of its previous rate.
Puberty is a time of tumultuous hormone levels, and nail growth is said to peak during this stage of life. As hormone levels balance out with age, nail growth declines. From the age of 20 onwards, the growth rate slows by about 0.5% per year.
The average adult's fingernails grow at a rate of around 3mm per month, or 0.7mm per week, although anywhere between 1.8mm and 4.5mm per month is considered normal. Toenails grow much slower than fingernails, at an average rate of 1.62mm per month, or 0.4mm per week.
There are some ways to increase the overall health of your nails, which can help them grow longer and stronger. Taking 2.5 milligrams of biotin every day has been shown to reduce breakage and increase overall nail health. Using nail hardeners can also strengthen nails, but they should be used sparingly as prolonged use can break down the nail over time.
Good nail hygiene can also help the growth process along. Keeping nails nicely trimmed, moisturising nails and cuticles, and regularly getting manicures and pedicures can all contribute to nail health.

The nails on your dominant hand grow faster
The growth rate of nails is influenced by several factors, including age, sex, season, exercise level, diet, and genetics. Typically, nails grow faster during childhood and puberty, then slow down as we age. While there are no scientifically proven methods to accelerate nail growth, certain practices can improve nail health and prevent breakage. These include taking biotin supplements, using nail hardeners sparingly, and maintaining good nail hygiene.
Interestingly, some people have observed that their dominant hand's nails grow faster. This phenomenon may be attributed to increased usage, leading to a higher risk of trauma. When trauma occurs, the body responds by increasing blood flow and nutrient delivery to the affected area, promoting repair and potentially influencing nail growth.
The nails on your dominant hand are more susceptible to catching on something or being hit, which can cause trauma and trigger the body's repair mechanism. This increased activity and risk of injury on your dominant hand may contribute to the perception that the nails on this hand grow faster.
It is worth noting that nail growth rates can vary between individuals and even between different hands. While the nails on your dominant hand may appear to grow faster, this could also be influenced by factors such as nail care, exposure to environmental conditions, and daily activities that involve using your hands.
Additionally, it is important to pay attention to any changes in your nails or their growth rate. If you notice any unusual symptoms or slow growth, it is recommended to consult a doctor. They can help identify any underlying causes, such as nutritional deficiencies or other health conditions, and provide appropriate advice or treatment options.

Toenails grow slower than fingernails
Fingernails grow at a rate of about one-tenth of an inch or 2.5 to 3 millimetres each month. This means that a lost fingernail will take around three to six months to completely grow back. On a weekly basis, fingernails grow at a rate of around 0.7 millimetres.
Toenails, on the other hand, grow at a slower rate of about 1/16 of an inch or 1.62 millimetres per month, or 0.4 millimetres per week. This means that toenails can take between a year to a year and a half to grow from cuticle to tip.
The difference in growth rates between fingernails and toenails can be attributed to various factors, including age, nutrition, season, gender, heredity, and nail use. Age plays a crucial role, with nail growth peaking during puberty and then slowing down as hormone levels stabilise with age. Children and young teens experience faster nail growth compared to adults. Additionally, nails tend to grow faster during warmer months and in individuals with dominant hand use.
While there are no scientifically proven methods to accelerate nail growth, certain practices can improve overall nail health and reduce breakage. These include taking biotin supplements, using nail hardeners sparingly, avoiding glue-on nails and toxic polishes, and maintaining good nail hygiene through regular grooming and moisturisation.

Nail biting can slow nail growth
Fingernails typically grow about one-tenth of an inch (2.5 to 3 millimetres) per month, or 0.7 millimetres each week. Toenails, on the other hand, grow at a slower rate, averaging around 0.4 millimetres weekly. Nail growth is influenced by a variety of factors, including age, health, and season. Children and adolescents experience faster nail growth than adults, with the rate decreasing by half after puberty.
Nail biting, or onychophagia, can negatively impact nail growth and lead to nail deformities. It can damage the tissue responsible for nail growth, resulting in abnormal-looking nails. Additionally, it can introduce harmful bacteria and viruses from the mouth to the fingers and face, increasing the risk of infection. To promote nail growth, it is important to address the habit of nail biting. This can be achieved through gradual behaviour changes, such as trimming nails short, applying bitter-tasting nail polish, or finding alternative ways to manage stress and boredom.
Breaking the nail-biting habit can be challenging, but it is possible with persistence and the right strategies. One approach is to gradually stop biting specific nails, such as thumb nails, and then move on to other nails once successful. Keeping nails well-maintained and trimmed can also reduce the temptation to bite them. Painting nails or getting them professionally done can serve as a deterrent, as the desire to preserve their appearance may outweigh the urge to bite.
In addition to behavioural strategies, certain products can help. Applying gel nail extensions can provide a protective barrier, allowing natural nails to grow longer and stronger underneath. However, it is crucial to ensure proper application and removal to avoid further damage. Bitter-tasting nail polishes, available over the counter, can also act as a deterrent by creating an unpleasant taste sensation when nails are bitten.
While nail biting can hinder nail growth, adopting these strategies can help break the habit and promote healthier, stronger nails over time. It is important to note that everyone's experience with nail growth and breaking habits may vary, so patience and persistence are key.

Good nail hygiene can help growth
Good nail hygiene can help nails grow faster and stay strong. Nails grow about one-tenth of an inch (around 2.5 to 3 millimetres) each month. However, this growth rate can vary depending on age, health, and other factors. For example, children and young teens experience faster nail growth than adults, with puberty being the peak time for nail growth. After puberty, nail growth slows down, and it may seem like broken nails take forever to grow back.
To maintain good nail hygiene and promote healthy nail growth, it is important to keep nails clean and dry. Bacteria and fungi thrive in moist environments, so ensuring nails are dry can prevent bacteria from growing underneath them. Regularly washing the hands with soap and scrubbing the underside of the nails can help keep nails clean. Additionally, it is recommended to trim nails straight across and slightly round them at the tips for maximum strength. Using sharp nail scissors or clippers is essential, and it is important to clean nail grooming tools before use.
Protecting nails from water exposure is also important. Excessive water exposure can weaken nails, causing them to split, peel, or break. Wearing gloves while cleaning or washing dishes can help minimise water exposure. Moisturising the nails and cuticles is another crucial aspect of nail hygiene. Using a hand lotion or moisturiser can keep the nails hydrated and healthy.
Certain habits, such as nail-biting, can damage nail health and increase the risk of infections. Avoiding nail-biting and not removing the cuticle can help maintain good nail hygiene. Additionally, it is advisable not to use nails as tools, such as opening cans, as this can cause chipping, splitting, or lifting of the nail bed. Keeping nails trimmed and shaped can help prevent biting and picking, reducing the risk of infections.
While there are no scientifically proven methods to accelerate nail growth, some practices can increase overall nail health and prevent breakage. Taking biotin supplements, for instance, has been shown in studies to improve nail health and reduce breakage. Using nail hardeners sparingly can also strengthen nails, but prolonged use may break down the nail over time. Avoiding glue-on nails and toxic polishes is recommended to lower the risk of breakage. Instead, opting for nontoxic or water-based polishes is a better alternative.
