What You'll Learn
Toenails take longer to grow back than fingernails
Nails grow back at different rates depending on various factors. The growth rate of nails is influenced by age, nutrition, season, and nail use. Nails grow continuously, but the speed of growth varies between individuals and even between nails on the same hand. On average, fingernails grow at a rate of 3.47 mm per month, while toenails grow at a slower rate of 1.62 mm per month.
This difference in growth rate is more pronounced when a nail needs to regrow after being lost or detached from the nail bed. It takes approximately six months for a lost fingernail to completely grow back, while a lost toenail can take up to 18 months to fully regrow. This extended period is because toenails are generally subjected to less trauma than fingernails. Although stubbing a toe can cause temporary pain, it does not have a lasting impact on the toenail's growth. In contrast, injuries to the fingernails, such as smashing them in a door or cutting them, can result in more severe trauma and require a longer recovery period for the nail to regrow.
The growth rate of nails can also be influenced by dominant hand use, with nails on the dominant hand tending to grow faster. This is because the dominant hand is used more frequently, increasing the risk of trauma to the nails. Additionally, nails tend to grow faster during the summertime, although the reason for this seasonal variation is not well understood. While there are no scientifically proven methods to accelerate nail growth, maintaining good nail hygiene and overall health can help strengthen nails and prevent them from breaking.
To maintain nail health and promote growth, it is recommended to keep nails clean and trim them regularly, approximately once a week. Pushing back or trimming the cuticles is also important. Additionally, moisturizing the nails and surrounding skin can help maintain nail health. If you notice unusual discoloration or slow nail growth, it is advisable to consult a doctor, as these symptoms may be indicative of underlying nutritional deficiencies or other health conditions.

Fingernails grow about 3.5mm per month
Fingernails grow at an average rate of about 3.5mm per month, or approximately a tenth of a millimetre per day. This means that it can take up to six months for a lost fingernail to grow back fully. In contrast, toenails grow back much slower, taking up to three to four times longer to grow back than fingernails. This means that it could take up to a year and a half for a toenail to grow back completely.
The rate at which fingernails grow is influenced by various factors. For example, nails on the dominant hand tend to grow faster, as do the nails on longer fingers. Similarly, fingernails grow faster during the day and in the summer. This may be due to the increased circulation associated with higher temperatures and physical activity.
Although there are no scientifically proven methods to make nails grow faster, certain vitamins and nutrients are believed to benefit nail health. These include biotin, folic acid (vitamin B9), and vitamin D. Biotin can be found in foods such as liver, nuts, salmon, avocados, sweet potatoes, and cauliflower. Folic acid is abundant in leafy green vegetables, citrus fruits, beans, cereals, and rice, while vitamin D is found in dairy products, fatty fish, and eggs.
Maintaining good nail hygiene can also support nail health and prevent issues such as discolouration and breakage. This includes keeping nails clean, trimming them regularly, and moisturising the surrounding skin. Additionally, protecting the cuticles is crucial as they shield the nails and fingers from fungal and other infections.

Nails grow faster in the summer
Fingernails grow at an average rate of 3.47mm per month, or about a tenth of a millimetre per day. If you lose a fingernail, it can take up to six months to grow back. Toenails, on the other hand, grow much slower, at an average rate of 1.62mm per month, and can take up to 18 months to grow back.
There are a few factors that affect the speed of nail growth. Firstly, nails on your dominant hand grow faster than the rest, as do the nails on your longer fingers. This is because you use your dominant hand more. Secondly, your fingernails grow faster during the day and, interestingly, during the summer. While there is no scientific explanation for this, it could be related to the increase in temperature and circulation during the warmer months.
Puberty is the peak of nail growth, and it declines as hormone levels balance out with age. Nail growth may also be affected by nutritional deficiencies or underlying health conditions. For example, people with diabetes or circulatory issues may experience slower nail growth or have trouble recovering from common nail disorders.
To support nail health and prevent breakage, it is recommended to take biotin supplements, use nail hardeners sparingly, and avoid glue-on nails and toxic polishes. Keeping your nails clean and moisturized is also key to maintaining their overall health.

Nails on your dominant hand grow faster
It takes about six months or longer for a fingernail to grow back, and toenails can take up to 18 months. The nails on your dominant hand are said to grow faster, as well as the nails on your longer fingers. This is because you use your dominant hand more, so it is more susceptible to damage. When your nail is damaged, your body will send resources such as blood and nutrients to repair the damage, which can also increase nail growth.
People who type a lot have faster-growing nails, so those with office jobs may notice this more. One source suggests that the nails on the dominant hand grow at twice the rate of the non-dominant hand. Interestingly, males' nails tend to grow faster than females', except during pregnancy or puberty when higher hormone levels speed up nail growth.
Fingernails also grow faster during the day and in the summer. This may be because higher temperatures cause blood vessels to expand, increasing blood flow and nutrients to the nails. Toenails grow much slower than fingernails as they are generally subject to less trauma.
There are no scientifically proven methods to make nails grow faster, but there are ways to increase their overall health. Keeping your nails clean is key to their health, so trim them regularly with a clean pair of clippers and push back or trim your cuticles. You can also take biotin to strengthen your nails and prevent them from breaking.

Good nail hygiene helps the growth process
It takes about six months or longer for a fingernail to grow back, and it can take up to 18 months for a toenail to fully regrow. The rate of nail growth is about 3.47 mm per month or about a tenth of a mm per day. The nails on your dominant hand grow faster, as do the nails on your longer fingers. Your fingernails also grow faster during the day and in the summer.
If you experience a nail injury, such as smashing your finger in a door or cutting it with a sharp object, you may be able to care for it at home if you can quickly stop any bleeding, the nail is still attached to the nail bed, and you only have a minor bruise. Remove any jewelry from your injured hand, gently wash any cuts or scrapes, and apply a bandage if needed. For more serious injuries, go to an urgent care center or emergency room. They will stop any bleeding and clean the wound, usually numbing the nail and finger or toe before treatment.
If your nails change, swell, or cause pain, see your dermatologist, as these can be signs of serious nail problems. If you have diabetes, poor circulation, or an immune system problem, it is especially important to seek treatment for any nail problems, as untreated nail injuries can lead to infection, foot ulcers, and other serious complications.
