Nail growth is influenced by several factors, including age, sex, season, exercise, diet, genetics, and overall health. On average, fingernails grow around 3 millimetres per month, while toenails typically take 12 to 18 months to regrow completely. The rate of nail growth is also impacted by habits such as nail-biting, which can increase circulation to the nail bed, leading to faster growth. Proper nail care, including cutting, filing, and moisturising, can help promote healthy nail growth and prevent breakage. Additionally, taking supplements like biotin and using nail hardeners sparingly can contribute to stronger and healthier nails.

What You'll Learn
Nail growth is influenced by overall health, age, hormones, and habits
Nail growth is influenced by a combination of factors, including overall health, age, hormones, and personal habits. On average, fingernails grow approximately 3.5 millimetres each month, while toenails grow at a slower rate of around 1.6 millimetres per month. However, this timeline can be affected by various factors.
Overall Health
The health of an individual's nails can often be an indicator of their overall health and nutritional intake. For example, brittle, weak, or peeling nails can be a sign of a poor diet or a vitamin deficiency, such as a lack of iron or biotin. Certain chronic conditions, such as hypothyroidism, can also affect nail health. Therefore, maintaining a balanced diet rich in whole foods or taking targeted supplements can promote healthier nail growth.
Age
Age is another factor that influences nail growth. As individuals age, they may notice changes in the texture, thickness, colour, and shape of their nails. These changes can be natural signs of ageing or indicators of underlying health conditions. For example, longitudinal melanonychia commonly develops in darker-skinned individuals as they age, and in rare cases, it could indicate skin cancer. Additionally, vertical ridges on the nails are common in older adults.
Hormones
Hormones also play a significant role in nail growth. During pregnancy, the high levels of oestrogen and progesterone can lead to rapid nail growth. On the other hand, nail growth tends to decline as hormone levels balance out with age. Oestrogen, in particular, is associated with strong and healthy nails, as it promotes collagen production and skin hydration.
Habits
Personal habits can also impact nail growth and health. Biting nails or picking at cuticles can damage the nail matrix and hinder growth. Maintaining good nail hygiene, such as keeping nails clean, trimmed, and moisturized, can support healthier nail growth. Massaging the cuticles can increase blood flow to the nail matrix and stimulate growth. Additionally, using nourishing oils and moisturizers during the massage can enhance nail flexibility and hydration.

Bitten nails grow faster than healthy nails
Fingernails grow at an average rate of about 3.47 millimetres per month or 0.1 millimetres per day. However, this rate can vary due to several factors, including age, sex, season, exercise level, diet, hereditary factors, and overall health. For instance, the nails on your dominant hand tend to grow faster because you use that hand more, increasing the risk of trauma to the nails.
One interesting phenomenon is that bitten nails seem to grow faster than healthy nails. Onychophagia, or chronic nail-biting, has been associated with a faster nail growth rate. This is because biting causes trauma to the nail, stimulating circulation in the nail bed underneath. This increased circulation delivers more blood and nutrients to the area, aiding in repair and accelerating nail growth.
While nail-biting may lead to faster regrowth, it is important to note that it can also damage the nail bed and negatively impact nail health. Maintaining good nail hygiene and overall health is crucial for supporting nail growth. This includes keeping your nails clean, trimming them regularly, and avoiding harmful practices such as using glue-on nails or toxic polishes. Additionally, taking biotin supplements and using nail hardeners sparingly can help strengthen nails and prevent breakage.
If you are struggling with onychophagia and want to grow healthy nails, there are several strategies you can try. Firstly, keeping your nails polished can deter biting, as you may be hesitant to ruin a nice manicure. You can also try using products like Nutra Nail Stressed Nail Formula, which can help your nails grow longer and faster. Additionally, addressing the underlying causes of nail-biting, such as stress or anxiety, through therapeutic interventions or lifestyle changes, may be beneficial.
In summary, while bitten nails may exhibit faster growth rates due to increased circulation and trauma, prioritizing nail health through proper care, nutrition, and stress reduction is key to achieving strong and healthy nails.

Nails on the dominant hand grow faster
On average, fingernails grow around 3 millimetres per month, while toenails grow much more slowly, taking between 12 and 18 months to regrow completely. The rate of nail growth is influenced by various factors, including age, sex, season, exercise level, diet, and hereditary factors.
Interestingly, the nails on your dominant hand tend to grow faster than those on your non-dominant hand. This is because you use your dominant hand more often, increasing the risk of trauma to the nails. When trauma occurs, your body sends more blood and nutrients to the area to aid in repair, stimulating nail growth. Similarly, people who type a lot may experience faster nail growth on the fingers they use for typing.
Nail growth can also be influenced by habits such as nail-biting or nail clipping. Biting your nails can increase the growth rate by three times compared to a healthy nail, as it causes trauma to the nail bed, stimulating circulation. Regular nail clipping has a similar effect, as it creates micro-traumas that encourage the nail to grow faster.
To promote healthy nail growth, it is important to practice good nail hygiene and ensure adequate nutrition. Keeping your nails clean, trimming them regularly, and using nail hardeners sparingly can help prevent breakage and maintain nail health. Additionally, taking biotin supplements and applying cuticle oil daily can strengthen your nails and enhance their growth.

Good nail hygiene helps speed up growth
Good nail hygiene is essential for maintaining nail health and promoting faster growth. While there are many factors that influence nail growth, such as age, sex, season, exercise, diet, and genetics, practicing good nail care can help support the process.
One aspect of good nail hygiene is keeping your nails clean and well-groomed. This includes regularly trimming your nails with a clean pair of clippers and filing them to ensure a smooth edge. Proper nail grooming can help prevent snagging or breaking, which can impact nail growth. Additionally, maintaining short and rounded nails can reduce the risk of trauma to the nail, such as catching your nail on something or hitting it accidentally.
Moisturizing your hands and nails is another important component of good nail hygiene. Dry skin can affect nail health, as very dry skin can crack and expose the nails to fungal and bacterial infections. By moisturizing regularly, especially during winter, you can help prevent nail damage and create an optimal environment for nail growth. This is particularly important for individuals with eczema, who should use highly moisturizing, eczema-friendly creams.
Good nail hygiene also involves taking care of your cuticles. Cuticles protect the nail matrix, so it is recommended to leave them intact and avoid cutting them too short. Instead, gently push them back and moisturize them regularly. Applying cuticle oil daily can help keep them healthy and prevent dead skin from growing on the nails.
In addition to external care, good nail hygiene includes considering your diet. Nails require a balanced diet with adequate protein, water, fruits, vegetables, and essential vitamins and minerals. For example, a deficiency in iron can lead to brittle or dented nails. Taking supplements or consuming a varied and nutritious diet can help ensure your body has the nutrients it needs to support nail growth.
While practicing good nail hygiene may not immediately speed up nail growth, it can help strengthen your nails, prevent breakage, and create the optimal conditions for healthy growth. By combining proper nail care techniques with a balanced diet, you can promote faster and healthier nail growth over time.

Biotin and nail hardeners can strengthen nails
While there is no magic solution for speeding up nail growth, maintaining strong and healthy nails can help encourage growth. One way to do this is by taking biotin supplements. Biotin is a B vitamin that promotes healthy cell growth and aids in the metabolism of protein-building amino acids, which are essential for nail growth. While biotin deficiency is rare, it can lead to brittle nails.
A 2007 study found that taking 2.5 milligrams of biotin every day reduced nail breakage and increased overall nail health. Another study of 35 people with brittle nails found that 2.5 mg of biotin per day for six weeks to seven months improved symptoms in 63% of participants. However, it's important to note that biotin is not a cure-all for nails, and it may not work for everyone.
In addition to biotin supplements, you can also find biotin naturally in certain foods. Biotin-rich foods include organ meats such as liver, egg yolk, dairy products, yeast, salmon, avocado, sweet potato, nuts, seeds, and even cauliflower. Consuming a variety of fruits, vegetables, nuts, and seeds can also help promote strong and shiny nails.
Another way to strengthen nails is by using nail hardeners. Nail hardeners may help reduce nail breakage and strengthen the nail. However, experts recommend using these products sparingly as prolonged use can break down the nail over time. It is also important to limit or avoid strengtheners that contain formaldehyde or formalin.
By incorporating biotin supplements or biotin-rich foods into your diet, as well as using nail hardeners sparingly, you can help strengthen your nails and encourage healthy nail growth.
