Fingernails grow at a rate of around 3mm per month, taking approximately four to six months to completely replace themselves. This process is influenced by various factors, including age, sex, and season. For instance, younger individuals tend to have faster nail growth rates, and nails typically grow faster in warmer months. Toenails, on the other hand, grow more slowly, usually at about half the rate of fingernails. While fingernails can regrow entirely in 3-6 months, injuries that affect the nail bed and matrix may cause slower growth for about the first three months. In cases of severe nail trauma, a portion of the nail or even the entire nail may detach from the nail bed, resulting in moderate pain and minimal bleeding. Although there is little that can be done to replace or repair a detached nail, proper medical care can promote healthy nail growth.

What You'll Learn
Fingernail replacement time
Fingernails grow from the nail matrix, which is located under the skin at the base of the nail. The matrix contains living cells that divide and produce keratin, a tough protein that allows the nail to grow longer. On average, fingernails grow approximately 3 mm or 0.13 inches per month, or about 1/10th of an inch per month. This equates to a total growth of about 18 mm in six months. Thus, it takes about four to six months for a fingernail to completely replace itself.
The growth rate of fingernails is influenced by various factors, including age, sex, and season. Younger individuals and men tend to have faster nail growth rates. Nails typically grow faster in warmer months than during winter, possibly due to the additional absorption of Vitamin D from increased sun exposure.
If a fingernail falls off due to an injury, it will usually grow back on its own within four to six months. However, proper medical care is required to ensure the nail matrix heals properly, and in severe cases of nail matrix damage, some or all of the nail may not regrow.
To promote nail health and faster regrowth, it is recommended to maintain a well-rounded diet and good general health. Vitamins such as biotin, folic acid/vitamin B9, and vitamin D are believed to be beneficial for nail growth and strength. Additionally, protecting the fingernails by wearing proper footwear and avoiding tight shoes can help prevent nail injuries and damage.

Toenail replacement time
One such solution is toenail reconstruction, which involves layering a specialist gel or resin on top of the nail bed or any remaining toenail. This gel is then cured under UV light to create a flexible, natural-looking nail that does not inhibit the growth of the natural nail underneath. This method typically lasts between 4 and 8 weeks, depending on how quickly your nail grows and the type of shoes you wear. If there is no remaining toenail for the resin to adhere to, the replacement may only last a day.
In some cases, a minor surgical procedure on the nail bed can improve the nail's appearance. Additionally, if you have a bruise under your nail, a procedure called nail trephination can be performed within 48 hours of the injury to drain the trapped blood and provide pain relief.
It's important to note that if there is damage to the nail matrix or nail bed, the new nail may grow back with defects or deformities. To promote healthy nail growth, it is recommended to keep your nails short, wear well-fitting shoes, and avoid barefoot activities that could result in further trauma to the toe.

Nail matrix healing
The nail matrix is the area under the base of the nail where growth originates from the division of stem cells. It is the "factory" where your body makes new fingernails and toenails. A healthy nail matrix is essential for healthy nails. A severe injury could cause your nail to fall off, but as long as there is no permanent damage to the nail matrix or nail bed, the nail should regrow normally and appear completely normal.
In the event of an injury that causes a fingernail to fall off, the new nail usually takes about four to six months to fully grow back. This process is influenced by various factors, including age, sex, and season. Younger individuals tend to have faster nail growth rates, and nails may grow slightly faster in men compared to women. Nails typically grow faster in warmer months than during winter.
If there is damage to the nail matrix, the growing nail plate will contain a defect. Minor damage will produce minor defects in the nail, while more significant defects can result in a permanently deformed nail. In cases of severe nail matrix damage, some or all of the nail may not grow back. However, it is rare for the nail matrix to be permanently damaged, preventing the nail from growing back. With the right treatment, you can often see healthy nails grow again.
To promote nail matrix healing and healthy nail growth, there are several things you can do:
- Keep your nails trimmed short.
- Moisturize your nails regularly, especially if you wash your hands frequently.
- Protect your nails from harm by wearing gloves when using cleaning products.
- Avoid picking or biting your nails, as this can easily cause damage.
- Strengthen your nails by forgoing nail polish for a few weeks to prevent bacteria and fungus from building up.
- Apply tea tree oil or lemon juice to damaged nails to battle infection and improve their appearance.

Preventing nail damage
It is important to take care of your nails to prevent damage and ensure healthy regrowth. Here are some ways to prevent nail damage:
Keep Nails Short and Trimmed: Maintaining short nails can help prevent nail damage and promote stronger regrowth. This is especially beneficial when healing from a toe injury, as short nails can reduce the risk of further damage.
Protect Nails from Trauma: Choose appropriate footwear that fits well and protects your nails and toes. Avoid going barefoot to minimize the risk of nail trauma. When handling heavy objects or working in construction, wear steel-toe boots for added protection. Be mindful of your surroundings to avoid accidents, such as stubbing your toe or injuring your nails in car doors or kitchen incidents.
Practice Good Nail Habits: Avoid using your nails to scratch or open things, as this can lead to breakage and tearing. Refrain from biting your nails or picking at them, as these habits can cause damage and hinder nail health.
Moisturize and Improve Nail Health: Regularly moisturizing your nails is crucial, especially if you wash your hands frequently. Consuming vitamins and nutrients, such as olive oil, eggs, carrots, sweet potatoes, and seafood, can help strengthen your nails and improve their overall health. Drink plenty of water to prevent dehydration and maintain healthy nail beds and cuticles.
Maintain Hand and Nail Hygiene: Keep your hands clean to avoid spreading fungal infections to your nails. Wear gloves when using cleaning products or when necessary to prevent irritation and contamination.
Seek Professional Care: If you have damaged nails or notice any color changes, pitting, ridges, or texture changes, consult a dermatologist or a reputable manicurist. They can provide treatment suggestions and help address any underlying issues affecting nail health.
By following these preventive measures, you can help minimize nail damage and promote the growth of strong and healthy nails.

Healing damaged nails
Fingernails and toenails are formed in the nail matrix, which is the "factory" where your body makes new nails. Certain injuries and illnesses can damage the nail matrix and affect how your nails look or grow. However, it is rare for the nail matrix to be permanently damaged. With proper care, it can heal, and healthy nails can grow again.
If a nail has been torn or detached, there is little that can be done to replace or repair it. If there is damage to adjacent structures, a visit to a physician may be necessary. If the nail bed and nail matrix are not damaged, the nail should regrow normally, although it may take between 3 and 6 months for fingernails to regrow entirely. Toenails grow more slowly, usually at about half the rate of fingernails. Nails that have sustained injuries affecting the nail bed and matrix grow more slowly than unaffected nails for about 3 months. Minor damage to the nail matrix will produce minor defects in the nail, while more significant damage can result in a permanently deformed nail.
To help heal damaged nails, it is recommended to avoid painting your nails for 2 to 3 weeks to allow them to heal and become stronger. Moisturizing nails daily with oil or serum can also help them heal faster. Oils such as jojoba oil, vitamin E, and cuticle oil can be beneficial. Tea tree oil is another option, especially if your nails are discolored, brittle, or emitting an odour, as it has anti-fungal properties. Soaking your nails in olive oil for 10 to 15 minutes daily can also be a cost-effective way to repair damaged nails.
To prevent further damage to nails, it is important to wear gloves when working with harmful substances or performing tasks that might be rough on your nails, such as doing household chores or cleaning. Cutting your nails properly and keeping them short can also help prevent ingrown toenails and accidental damage. Additionally, avoiding nail-biting and picking can help, and coating your nails with a bitter-tasting substance or wearing socks or mittens at night may deter these habits.
