Toenails are made of keratin, the same protein that makes up our skin and hair. They protect the soft tissue beneath them and keep the tips of our toes safe. Losing a toenail can make walking or jogging uncomfortable. Toenails grow at about 1.62mm per month, taking anywhere from 6 months to 2 years to grow back fully. The rate of regrowth depends on several factors, including the reason for the loss of the nail, overall health, age, climate, and adequate intake of certain vitamins.

Toenail regrowth timeline
Toenail regrowth can take anywhere from 6 months to 2 years, depending on the reason for the nail loss and various other factors. Here is a detailed timeline of the toenail regrowth process:
Initial stages
In the beginning stages of toenail regrowth, it is important to keep the exposed nail bed clean and protected. This can be done by applying a thin layer of petroleum jelly to the nail bed, which helps keep the wound moist, promoting faster healing and preventing scabbing. A non-stick bandage can then be used to cover the area, protecting it from infection and reducing pain from friction with socks and shoes. It is recommended to change the bandage daily or whenever it gets wet or dirty.
First few months
During the first few months of toenail regrowth, the nail bed will start to heal, and a new nail will begin to form. Nails grow at an average rate of 1.62mm per month, so after about 4-6 months, a new nail should start to cover the nail bed. During this time, it is important to continue caring for the nail bed and new nail by keeping it clean, moisturized, and protected.
6 months to 1 year
At the 6-month mark, the new toenail should be more established, but it may still be thinner and more delicate than the surrounding nails. It is important to continue protecting the nail and encouraging healthy growth. This can include maintaining proper foot hygiene, trimming nails straight across, and avoiding tight-fitting shoes that can constrict the toes and slow nail growth.
1 year and beyond
After about a year, the toenail should be well on its way to full recovery. However, in some cases, it may take up to 2 years for the nail to fully regrow and regain its strength and smoothness. To support the final stages of toenail regrowth, maintaining overall health and addressing any underlying conditions that may impact nail growth is crucial. This includes managing conditions such as nail fungus, psoriasis, or hormone imbalances, which can affect the speed and appearance of nail regrowth.

Factors affecting toenail growth
Toenails take approximately 1.62mm per month to grow, which is slower than the growth rate of fingernails. Several factors influence the growth rate of toenails, and understanding these factors can help promote healthy nail growth.
Firstly, the health and strength of the nail itself play a crucial role in its growth. Nails are made of keratin, a protein that also constitutes our skin and hair. Therefore, maintaining adequate keratin levels is essential for nail growth. Similarly, collagen, another essential protein for nail structure, decreases with age, resulting in brittle and slow-growing nails. Supplemental collagen has been linked to increased collagen levels and improved nail strength and growth rate.
Additionally, overall health and nutrition significantly impact nail growth. Malnutrition or deficiencies in certain vitamins and minerals can hinder nail growth. Hormonal changes, such as during pregnancy or puberty, can also affect nail growth rates, with nails growing faster during these periods due to fluctuating hormone levels.
External factors, such as the time of year and climate, also come into play. Nails tend to grow faster during the summer and in warmer climates. Moreover, trauma or injury to the nail can increase the rate of regrowth due to increased blood flow to the affected area. However, severe trauma, such as stubbing your toe or dropping something on it, can cause nail loss and significantly slow down regrowth, taking anywhere from 6 months to 2 years for the nail to fully recover.
Lastly, certain medical conditions and their treatments can influence nail growth. For example, psoriasis, a skin condition that can affect the nails, may require medication that improves nail appearance and promotes growth. Toenail fungus, a common issue due to the warm and wet environment created by shoes and socks, can also impact nail growth and may require medical intervention.

Toenail loss causes
Toenails are made of keratin, a protein that also makes up our skin and hair. They protect the soft tissue beneath them and keep the tips of our toes safe. However, it is not uncommon to lose a toenail. Toenail loss can occur due to various reasons, including:
Trauma or injury
Accidents, sports, stubbing your toe, or dropping something heavy on your foot can damage your toenail. This can cause a subungual hematoma, leading to blood collecting under your injured toenail. As blood accumulates, the toenail may separate from the nail bed and eventually fall off.
Fungal infections
Fungal infections are another common cause of toenail loss. Toenails are susceptible to these infections as fungi thrive in warm, wet environments, such as shoes and socks. Symptoms of a fungal infection include yellow or dark discolouration, brittleness, and thickening of the nails.
Medical conditions
Underlying medical conditions, such as psoriasis, an autoimmune disease that causes skin cell buildup, can also lead to toenail loss. Toenails may fall off due to the buildup of skin cells in the nail bed. Additionally, diseases that cause poor circulation, such as Raynaud's, can contribute to toenail breakage or crumbling.
Allergies and side effects
Allergies to nail product ingredients, certain medications, and their side effects can also result in toenail loss.
Age and nutrition
Age and nutrition also play a role in toenail health. As we age, our bodies produce less collagen, resulting in brittle and slow-growing nails. Malnutrition can also slow down nail growth, affecting the time it takes for a toenail to regrow.

Toenail care during regrowth
Toenail regrowth is a slow process, typically taking anywhere from 6 months to 2 years. During this time, there are several things you can do to care for your toenail and encourage healthy regrowth. Here are some tips for toenail care during the regrowth process:
Keep the Area Clean and Protected
It is important to keep the injured area clean and protected from further injury. Make sure to follow any home care instructions provided by your doctor, especially if you had a nail surgically removed. Keep the nail bed covered and wear well-fitting shoes to encourage healthy nail growth and protect the sensitive skin underneath. Avoid wearing shoes that are too small, as this can bruise your toenails and aggravate the injured nail bed. Opt for breathable cotton socks instead of tight or pantyhose.
Elevate the Injured Toe
In the initial days after losing a nail, keep the injured toe elevated to reduce blood flow to the area, which can help decrease swelling and bruising.
Take Biotin Supplements
Biotin supplements promote cell growth and help your body metabolize protein-building amino acids, contributing to faster nail growth.
Apply a Cold Compress
Reduce swelling and inflammation by applying a cold compress to the injured area. Wrap a cloth over an ice pack before applying it to your skin for up to 20 minutes.
Maintain Good Overall Health
Overall health can impact nail growth. Ensure you are getting proper nutrition, exercise, and adequate rest. Nail growth can slow down if you are sick or malnourished, and certain health conditions like diabetes can also affect the speed of regrowth.
Seek Professional Help
In some cases, it may be necessary to seek help from a podiatrist or other specialist, especially if the nail matrix is severely damaged or if you are experiencing issues with fungal infections. They can provide professional advice and treatment to ensure your nail grows back healthy and strong.

Toenail fungus
To treat toenail fungus, it is recommended to see a podiatrist, especially in advanced cases. They may file down the nail and prescribe topical treatments. In some cases, the entire toenail may need to be removed to allow a new one to grow. While waiting for your appointment, you can practice good hygiene by keeping your feet and toes clean and dry. Trim your toenails straight across, and avoid cutting into the sides to prevent ingrown toenails. Disinfect your nail-cutting tools and avoid applying polish to infected nails.
To promote nail growth, you can take biotin supplements, which contribute to faster nail growth by promoting cell growth and protein metabolism. Collagen supplements and a nutrient-rich diet can also support nail growth. Additionally, maintaining good overall health and hygiene practices is essential for nail growth. Keep the wound covered, and if there is pain, take OTC anti-inflammatory medications.
The time it takes for a toenail to grow back depends on various factors. On average, it can take up to 18 months for a toenail to completely regrow, but this can vary from 6 months to 2 years. Nails tend to grow slower in older adults and in colder climates, while trauma or injury can increase the rate of regrowth due to increased blood flow to the area. Overall health also impacts growth, with slower growth observed in individuals who are sick or malnourished.
