Nails are produced by the nail matrix cells that reside in the whitish moon-shaped area (lunula) at the base of the nail. The nail matrix is the factory where your body makes new fingernails and toenails. If the nail matrix is not damaged, the nail should regrow. However, 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 damage can result in a permanently deformed nail. If the entire nail is detached from the finger or toe, there is nothing that can be done to repair, reattach, or replace it. While there is only so much you can do to speed up the process, there are several things you can do to help your nail regrow.

What You'll Learn

Keep the nail bed dry, clean, and covered
Keeping the nail bed dry, clean, and covered is essential for preventing infection and promoting healing. Here are some detailed instructions to help you do this effectively:
Keep it Dry:
- Avoid getting the nail bed wet, especially during the first 24 hours after injury.
- If you need to wash your hands or shower, try to keep the affected area dry. You can use a waterproof bandage or tape to cover the nail bed before exposing it to water.
Keep it Clean:
- Gently clean the exposed nail bed and the surrounding area with mild soap and warm water to remove any dirt or debris.
- Rinse well and pat dry with a clean cloth or cotton ball.
- Consider soaking the injured nail in a saltwater solution a few times a day. Create a solution by mixing 1 teaspoon of salt with 4 cups of warm water. Soak your nail for about 20 minutes at a time. Saltwater soaks can help keep the area clean, prevent infection, and promote healing.
Keep it Covered:
- Apply a thin layer of petroleum jelly to the nail bed to protect and moisturize it.
- Cover the nail bed with a non-stick, breathable bandage. Change the bandage daily or whenever it gets wet or dirty.
- If you have sharp edges or a partially detached nail, you can trim or file them to prevent snagging and further injury. Then, cover the nail with tape or an adhesive bandage until it has grown out enough to protect the finger or toe.
Remember, it is essential to keep the nail bed dry, clean, and protected to create optimal conditions for nail regrowth and prevent complications during the healing process.

File or trim sharp edges
If your nail is torn or detached, it is important to file or trim sharp edges to prevent the nail from catching and tearing further. This is especially important if you have long nails, as they are more prone to damage. Nails can pry away from the nail bed when hit or jammed, so filing or trimming sharp edges can help to prevent further injury.
To file or trim sharp edges, you can use nail scissors or a nail file. If part of your nail has ripped off, carefully cut away the detached portion with nail scissors, then file or trim any jagged edges. This will help to prevent the rest of the nail from snagging on things and causing further pain or injury. It is important to be gentle when filing or trimming to avoid causing further damage to the nail or the surrounding skin.
If your nail has completely detached, you may need to trim off the detached part before filing or trimming the sharp edges. This can help to prevent the nail from catching and tearing, which can be painful and may cause further damage. Once the sharp edges have been filed or trimmed, you can cover the nail with tape or an adhesive bandage to protect it while it heals.
In some cases, you may be able to repair a broken nail using dip powder and nail glue. This involves dabbing glue over the break and then dipping the nail into translucent dip powder. The process can be repeated multiple times, and the nail can then be buffed and painted over. However, it is important to note that this method may not be suitable for all types of nail injuries.
Overall, filing or trimming sharp edges is an important step in treating a torn or detached nail. It helps to prevent further injury and promotes healing. It is important to be gentle and careful when filing or trimming to avoid causing further damage to the nail or surrounding skin.

Soak the nail in saltwater
While there is no scientific evidence that soaking your nails in saltwater will make them grow faster, it does have other benefits. Soaking your nails in warm water can improve circulation to the nail beds, which may promote growth. Salt can also help to exfoliate and remove dead skin cells.
To make a saltwater soak, combine warm water with a pinch of salt. You can also add other beneficial ingredients, such as avocado or olive oil, vitamin E, and lemon juice. Soak your nails for 10 to 15 minutes every other day. After soaking, massage the mixture into your cuticles and the top and underside of your nails. Then, wipe it off with a cloth and rinse your hands with water after an hour.
It's important to note that nail growth is primarily influenced by genetics and overall health. Maintaining a balanced diet rich in nutrients like protein, biotin, and vitamins that support nail health is crucial for promoting nail growth. Additionally, keeping your nails clean, trimmed, and moisturized can contribute to their overall health.
If you have experienced nail trauma or have any concerns about your nail health, it is always best to consult a healthcare professional for personalized advice and treatment options.

Take biotin supplements and vitamins
While you wait for your nail to grow back, it's important to be patient and not disturb or chip at it. Nails grow slowly, with fingernails taking 3-6 months to fully regrow and toenails taking up to 18 months.
In the meantime, there are some simple things you can do to help support the healing process and promote faster nail growth. Taking biotin supplements and certain vitamins can stimulate or stabilize hair and nail growth. Biotin is a B vitamin that can help strengthen nails and support their growth. It's always a good idea to speak to your doctor before starting any new supplement to ensure it's right for you and your individual needs.
In addition to taking biotin supplements, maintaining a well-rounded diet and good general health can contribute to strong and healthy nails. This includes ensuring you are getting a variety of nutrients through your diet, such as vitamins and minerals, which can support nail growth and overall health.
If you have any underlying health conditions that may impact your nail growth, it's important to manage these through proper treatment. Certain conditions can weaken or damage nails, so seeking appropriate medical care can help promote healthy nail growth.
While taking biotin supplements and vitamins can be beneficial, it's also important to combine this with other nail care practices. Keeping the nail bed clean, dry, and moisturized can promote faster healing and prevent infection. You can apply a thin layer of petroleum jelly to the nail bed and cover it with an adhesive bandage, changing it daily or whenever it gets wet or dirty. Soaking your nails in a warm saltwater solution 2-3 times a day can also help to moisturize the area, kill bacteria, and promote healing.

Cut your nails properly
Nails grow a little more than one-tenth of an inch per month and require 3-6 months to completely regrow. Toenails grow more slowly than fingernails, usually taking up to 18 months to grow back. Nails are produced by the nail matrix cells that reside in the moon-shaped whitish area (lunula) at the base of the nail. The lunula is the only visible part of your nail matrix.
Since nails are located at the back of our fingertips and toes, they are prone to damage. Longer nails are more likely to become damaged because they can be levered off the nail bed or run into the end of an athletic shoe. Poorly fitting shoes are likely to injure nails through repeated trauma. Nails may also separate from the nail bed due to injury, fungal nail infection, or skin conditions such as psoriasis.
To prevent nail damage and promote healthy nail growth, it is important to cut your nails properly. Here are some tips for cutting your nails to promote healthy growth:
- Trim your nails regularly: Keeping your nails at a manageable length can help prevent them from becoming too long and prone to breakage or tearing.
- Trim toenails straight across: Cutting your toenails straight across can help prevent ingrown toenails, which can be painful and increase the risk of infection.
- Use the right tools: Invest in a good-quality nail clipper or scissors designed for nails. This will ensure a clean and precise cut, reducing the risk of nail damage or injury.
- File your nails: After trimming your nails, use a nail file to smooth the edges. This will help prevent sharp edges that can catch on things and lead to tearing. It will also give your nails a neat and well-groomed appearance.
- Avoid cutting nails too short: Leave a small amount of white visible when trimming your nails. Cutting nails too close to the skin can increase the risk of injury and pain.
- Be gentle: Avoid cutting your nails too aggressively or using excessive force. Take your time and be gentle to prevent any accidental cuts or injuries to the surrounding skin.
By following these tips for cutting your nails properly, you can help promote healthy nail growth and reduce the risk of nail damage and injury.
