Damaged nails can be painful and unsightly. Nails take a while to grow out, and the process can be uncomfortable and inconvenient. The regrowth process can take anywhere from eight weeks to six months, depending on the severity of the damage and whether the nail bed and matrix were affected. Nails grow at a rate of 0.13 inches per month, and minor defects may show up in the nail if the nail matrix was damaged. Proper nail care and hydration can help speed up the process and ensure that your nails grow out healthy and strong.

What You'll Learn

Nails grow at 0.13 inches per month
The rate at which nails grow depends on various factors, including which finger the nail is on, your age, hormone levels, and overall health. Typically, fingernails grow at a faster rate than toenails. While fingernails grow at an average rate of 3.47 mm per month, or about a tenth of a millimeter per day, toenails grow at an average rate of 1.62 mm per month. This means that fingernails grow at about 0.13 inches per month.
If you lose a fingernail, it may take up to six months for it to completely grow back, and it may take even longer if the nail bed or matrix was damaged. Fingers or toes that have sustained injuries affecting the nail bed and the matrix grow more slowly than unaffected nails for about three months. 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.
The nails on your dominant hand tend to grow faster than those on your non-dominant hand. Similarly, the nails on your longer fingers tend to grow faster than those on your shorter fingers. For example, the little finger's nail grows slower than the other fingernails. Nail growth also tends to be faster during the summer and during the day.
While there aren't any scientifically proven methods to make nails grow faster, there are ways to increase their overall health and prevent them from breaking. For instance, taking biotin supplements can help strengthen your nails.

Toenails grow slower than fingernails
Growing out damaged nails takes time, and there is no shortcut to speed up the process. Generally, fingernails grow at a rate of 0.13 inches per month, and toenails grow at almost half that rate. This means that fingernails can completely regrow in 3 to 6 months, while toenails will take longer. Nails that have been injured or damaged grow more slowly than healthy nails for about 3 months. If there is damage to the nail matrix, the growing nail will have defects, and significant damage can result in a permanently deformed nail. Minor damage will produce minor defects in the nail.
To promote the growth of strong and healthy nails, it is important to take care of your overall health and ensure you are not immunocompromised or malnourished. Grooming your nails and trimming them regularly is crucial for nail health. Avoiding contact with allergens and irritants, such as detergents or solvents, can help reduce nail breakage. Minimizing the use of nail gels or acrylics is also recommended, as they can wear down the nail surface over time.
For individuals with brittle nails, biotin (vitamin B7) supplements may offer nail-strengthening benefits. Small clinical trials have shown that biotin supplementation may improve the firmness, thickness, and hardness of nails. It is important to be consistent with any nail care regimen to see effective results.
In cases of severe nail damage, such as a detached or torn nail, there is little that can be done to replace or repair the nail. The primary concern is to prevent damage to the surrounding structures and to ensure proper healing. If there is significant damage to the tissues around the nail, it is essential to seek medical advice to assess the need for repair or treatment.

Nail damage may cause permanent deformation
Injuries to the nail bed, such as crushing or grinding, can lead to partial or complete nail loss and potential permanent deformation. Blunt trauma to the nail can cause bleeding between the nail and the nail bed, known as a subungual hematoma. If the injury affects the nail matrix, the growing nail plate may contain defects, ranging from minor to significant. These defects can result in permanent nail deformities, such as ridges, splits, or changes in nail shape and texture.
Additionally, certain habits and medical conditions can contribute to nail damage and potential permanent deformation. Nail-biting, picking objects with the nail, or improper manicure practices can lead to nail deformities. Medical conditions such as psoriasis, nail matrix melanoma, vitamin deficiencies, and thyroid diseases can also affect nail health and appearance, potentially causing dents, ridges, cracks, spots, and texture changes.
To prevent permanent nail deformities, proper management and treatment of nail injuries are crucial. Seeking medical attention and following recommended treatments can help promote nail healing and reduce the likelihood of permanent deformation. In some cases, surgical procedures or grafting techniques may be necessary to restore the nail's appearance and function.
The time it takes for damaged nails to grow out and return to their normal appearance can vary. Fingernails typically grow at a rate of about 0.13 inches per month, with toenails growing slower. It may take several weeks to a few months for new nail growth to become apparent, depending on the severity of the damage. Consistency in nail care and treatment is essential for optimal results.

Keep nails hydrated and moisturised
Keeping your nails hydrated and moisturised is essential for maintaining their health and appearance. Proper nail hydration can prevent various nail issues such as brittleness, slow growth, and breakage. Hydrated nails tend to have a smoother texture and a healthier shine.
One common misconception is that drinking more water will automatically lead to hydrated nails. While staying hydrated is crucial for overall health, nail hydration requires more than just increasing your water intake. Nails are made up of keratin, a protein that needs external moisture to stay healthy and strong. However, drinking plenty of water and other hydrating fluids is still essential for your nail's health, as it hydrates your nails from the inside out.
To maintain optimal nail health, it is crucial to incorporate regular hydration practices into your nail care routine. Applying a moisturising nail oil or cream regularly can significantly improve nail hydration and prevent brittleness. It is important to choose products with nourishing ingredients such as vitamin E, jojoba oil, or almond oil to nourish and strengthen the nails. Additionally, using a moisturising hand cream after washing your hands can prevent your nails from drying out and becoming brittle.
Lifestyle changes can also improve nail hydration. Ensuring a balanced diet rich in essential nutrients such as biotin and omega-3 fatty acids can promote nail health and hydration. Nails that have sustained injuries affecting the nail bed and matrix may grow more slowly for about three months. In addition, wearing gloves while doing household chores or gardening can protect your nails from damage and dryness, keeping them moisturised and strong.

Take supplements to aid nail growth
While consuming a variety of vitamins, minerals, and nutrients through food is the best way to improve and maintain nail health, taking supplements may be beneficial in certain circumstances.
Biotin supplements are the only type of supplement that has been shown to have a possible effect on nail growth and health. Biotin deficiency is rare, but consuming biotin through foods or supplements may help strengthen brittle nails and improve their growth. Other B vitamins are also important for nail health. For instance, vitamin B12 plays a role in iron absorption and the development of red blood cells, both of which are necessary for keeping nails strong and healthy. A deficiency in vitamin B12 can result in discolored nails, while a deficiency in folate or vitamin B9 can cause a pigment change and make nails rigid and brittle.
Zinc is another essential mineral for the healthy growth of nails. Animal proteins are a great way to consume adequate zinc through your diet, though certain plant foods pack this mineral as well.
Collagen-boosting capsules are another supplement that has been shown to have positive effects on nail growth and strength. Testers of these capsules reported stronger nails and faster growth, with less breakage.
It is important to note that scientific research on the effectiveness of nail supplements is limited. While supplements may help, consuming a nutrient-rich diet with a variety of fruits, vegetables, nuts, and seeds, as well as adequate protein and omega-3 fatty acids, is likely the best way to achieve strong, shiny, and healthy nails.
