Toenails grow at a slower rate than fingernails, taking up to 18 months to fully regrow. Fingernails, in comparison, take about 4 to 6 months to grow back. Toenails grow at an average rate of 1.62 mm per month, while fingernails grow at about 3.5 mm per month. Toenails are more susceptible to fungal infections due to the warm and wet environment of the feet. Factors such as overall health, nutrition, and proper nail care can influence the growth rate of toenails. Maintaining a balanced diet that includes biotin, a vitamin B complex, can promote nail health and strengthen brittle nails.

What You'll Learn
Toenail growth rate
Toenails grow at a rate of about 1.62mm per month, which is less than half the rate of fingernail growth, which is about 3.47mm per month. Toenails take 2-3 times longer to regrow compared to fingernails. On average, it takes up to 18 months for a toenail to completely regrow, whereas it takes about 4 to 6 months for a fingernail to grow back.
Toenail regrowth tends to be slower after an injury or trauma, taking anywhere from 6 months to 2 years. The rate of regrowth may also depend on the reason for the loss of the nail in the first place. If you are simply engaging in standard hygienic trimming practices with your toenails, you will likely notice them growing back at a faster rate than if an injury or nail fungus is involved.
Toenails are susceptible to fungal infections because fungi thrive in warm, wet environments. Symptoms of toenail fungus include yellow or dark discolouration, brittleness, and thickening of nails. Over-the-counter (OTC) and prescription products can treat nail fungus, but it can take 12 to 18 months for the fungus to grow out. Surgical removal of a nail might be necessary in severe cases of fungus, recurrent ingrown toenails, or when a large section of a nail is diseased or damaged. After medical removal, it can take up to 18 months for a nail to fully regrow.
To promote toenail growth, you can take biotin supplements, which promote cell growth and help your body metabolize protein-building amino acids. Consuming a nutrient-rich diet, taking collagen supplements, and practicing good hygiene and grooming can also help boost nail growth.

Toenail loss causes
Toenail loss is a common condition that can be caused by several factors, including trauma, infection, or other medical conditions. Here are some of the most common causes of toenail loss:
Trauma or Injury
Accidents, sports injuries, or dropping heavy objects on the foot can cause toenail trauma or injury. This can lead to a condition called subungual hematoma, where blood collects under the toenail, causing it to separate from the nail bed and eventually fall off. Wearing ill-fitting shoes that put constant pressure on the toes can also lead to toenail loss.
Fungal Infections
Fungal infections are a common cause of toenail loss. Symptoms include yellow or dark discolouration, brittleness, and thickening of the nails. Over time, the infection can cause the nail to become loose and eventually fall off. Fungal infections can be treated with over-the-counter or prescription medications, but severe cases may require surgical removal of the nail.
Medical Conditions
Certain medical conditions can increase the risk of toenail loss. For example, people with diabetes may experience slower nail growth and a higher susceptibility to infections, delaying the regrowth process. Psoriasis, an autoimmune condition affecting the skin and nails, can also cause toenail loss. Additionally, allergies to nail product ingredients and poor circulation due to diseases like Raynaud's can contribute to toenail loss.
Age, Health, and Individual Biology
Age, overall health, and individual biology play a role in toenail loss and regrowth. Nails tend to grow slower in older adults and those with malnutrition or certain hormone imbalances. Regrowth can also be influenced by factors such as the extent of the damage, individual biology, and climate, with nails growing slower in colder environments.

Toenail fungus
Toenails are particularly susceptible to fungal infections because fungi thrive in warm, wet environments. To prevent toenail fungus, it is important to keep your feet clean and dry. Wash your feet and toes with warm, soapy water and dry them thoroughly before putting on socks and shoes. Avoid keeping your feet covered with socks and shoes when at home. When cutting your toenails, trim them straight across, disinfect your nail-cutting instruments, and avoid cutting or pushing back your cuticles, as this can break the seal between the nail and the skin, allowing bacteria and fungus to enter.
If you do contract toenail fungus, over-the-counter treatments are available, and you should see a podiatrist for prescription treatments. However, even the best over-the-counter treatments may not prevent a fungal infection from recurring. In severe cases, surgical removal of the nail may be necessary to allow a fresh one to grow in. After medical removal, it can take up to 18 months for a toenail to fully regrow.

Toenail care
Toenails grow about 1.6 mm per month on average, which is less than half the rate of fingernails. Toenails take about 12 to 18 months to regrow fully after losing a nail.
- Wash your feet and toes regularly with warm, soapy water and a mild soap. Dry them thoroughly before putting on socks and shoes.
- Trim your toenails regularly, cutting straight across. Avoid cutting into the sides of your nails to prevent ingrown toenails. Finish with light filing to smooth out any rough edges.
- Avoid cutting or pushing back your cuticles. Cuticles protect your nail bed from infection. Instead, use a cuticle stick to gently push them away from the nail bed.
- Choose proper-fitting shoes to avoid friction and rubbing, which can lead to ingrown toenails and nail bed damage.
- Manage perspiration with medicated powders and moisture-wicking socks, such as those made from wool or bamboo.
- Avoid wearing nail polish constantly, as nails need airflow to stay healthy. Give your nails a break between pedicures and remove all old polish before applying a new coat.
- See a podiatrist if you have any concerns about your toenails or foot health. They can help treat issues such as nail fungus and ingrown toenails.
By following these toenail care tips, you can help ensure your toenails stay strong, smooth, and healthy.

Toenail regrowth tips
Toenail regrowth is a slow process and can take anywhere from 6 months to 2 years for the toenail to fully regrow. The rate of regrowth depends on various factors, such as age, health, and injury type. Here are some tips to help promote toenail regrowth:
Keep the Wound Clean and Covered
Clean and dry your nail bed daily and cover it with a bandage. Change the bandage once a day to keep the area clean and protected. You can also apply an antibiotic ointment to the damaged nail to prevent infection.
Take Biotin Supplements
Biotin supplements promote cell growth and help your body metabolize protein-building amino acids, contributing to faster nail growth. Talk to your doctor about using supplements to support the healing process.
Maintain Good Foot Care Habits
Wear shoes that fit well to avoid further injury. Wear breathable cotton socks instead of tight or pantyhose. Keep your toenail clean and moisturized. You can also soak your nail in a saltwater solution to moisturize the area and prevent infection.
Seek Professional Help
If needed, seek help from a podiatrist or a specialist in foot health. They can provide personalized care and support to ensure your nail grows back healthy and strong.
Support Your Overall Health
Good nutrition, exercise, and overall health can positively affect the speed of nail regrowth. Maintain a balanced diet and stay hydrated to support your body during the healing process.

Frequently asked questions
Toenails can take anywhere from 6 months to 2 years to grow back. The rate of growth depends on the cause of the loss of the toenail, the size of the lost toenail, and the health of the individual.
There are several things you can do to help your toenail grow back faster. You can take biotin supplements, which promote cell growth and help your body metabolize protein-building amino acids. You can also soak your foot in saltwater for the first 3 days after losing your nail, keep the nail bed clean and dry, and watch for signs of infection.
Toenails can fall off due to trauma, such as dropping something heavy on the toenail, stubbing your toe, or wearing poorly fitting shoes. They can also fall off due to fungal infections, which can be caused by poor circulation in the feet, a weakened immune system, or taking medications that suppress the immune system.
