Fingernails, including thumbnails, take anywhere from three to six months to regrow, depending on the individual. Toenails, on the other hand, can take up to a year and a half to fully regrow. The rate of nail growth is influenced by various factors, including age, nutritional status, environmental temperature, trauma, handedness, pregnancy, acute illness, and pre-existing skin conditions. Maintaining a well-rounded diet and good general health can help promote strong nail growth. Additionally, supplements like biotin and bone broth, which contain collagen, can aid in speeding up the regrowth process.

What You'll Learn
Thumbnail regrowth rate
The regrowth rate of thumbnails varies depending on several factors. Firstly, it is well-documented that nail growth slows with age. For example, William Bean observed that his left thumbnail grew at a rate of 0.123 mm per day when he was younger, but this rate had dropped to 0.095 mm per day by the time he was 67 years old.
Secondly, the growth rate of thumbnails can be influenced by hormones. For instance, pregnancy can affect nail growth rates. Other factors that can impact thumbnail regrowth include nutritional status, environmental temperature (with faster growth in warm months), trauma, handedness (with faster growth in the dominant hand), acute illness, and pre-existing skin conditions.
Additionally, the status of the nail itself, whether intact or avulsed, can contribute to the rate of growth. Nails grow back slowly, and it typically takes about 3 to 6 months for a fingernail to fully regrow, with toenails taking twice as long. The thumbnail, in particular, has one of the slowest rates of growth among the fingernails, along with the little fingernail.
To promote thumbnail regrowth, it is recommended to maintain a well-rounded diet and good general health, as this can help produce strong nails. Consuming foods rich in biotin, such as spinach and other vegetables, and bone broth, which contains collagen, can help speed up nail growth. Additionally, filing any sharp edges smooth or trimming the nail can help prevent further tearing and damage.

Factors affecting nail growth
It takes around 3 to 6 months for a thumbnail to regrow. Several factors influence the rate of nail growth, and understanding these factors is important for medical reasons and for achieving healthy nails.
Age
Nail growth slows down as people age. Children around the age of 10 tend to experience more rapid nail growth than adults.
Gender
Men's nails tend to grow quicker than women's.
Diet
A healthy diet helps nails grow stronger and faster. Food rich in vitamins, minerals, and protein is essential for healthy nails. For example, biotin, found in spinach and other vegetables, helps speed up nail growth.
Medication
Certain medications can affect nail growth, making it faster or slower, and also impacting nail strength. For instance, chemotherapy medication can drastically affect nail growth.
Illness
Illness slows down nail growth as the body uses its available nutrients to fight the illness.
Pregnancy
Pregnancy speeds up nail growth due to increased hormone production. During pregnancy, the body produces larger quantities of estrogen and progesterone, which accelerate nail growth.
Circulation
Poor blood circulation slows down nail growth as the nail receives fewer nutrients and less oxygen.
Climate
Nails grow faster in hotter environments, meaning that nail growth rates vary across different times of the year.
Location
The location of the nail on each finger affects growth rates. For example, the nail on the pinky finger grows differently from the thumb.
Additionally, endogenous and exogenous factors, such as seasonal variations, weather conditions, trauma, and chemical exposure, can also influence nail growth rates.

Nail damage and treatment
Nails are delicate and can be damaged in several ways, including cuts, tears, and bruises. A common cause of nail injuries is the crushing of fingers or toes by heavy objects, resulting in a subungual haematoma, which is when blood pools between the nail and the nail bed, causing a bruise. Treatment for this involves draining the blood through a small hole drilled in the nail, a procedure known as trephination. In some cases, the nail may need to be removed to repair the nail bed.
If any part of your nail is hanging off, gently trim away the part that is not connected to your skin. Clean the wound with soap and water, and if there is bleeding, avoid using a dry bandage or gauze as it will stick to the wound. Instead, apply petroleum jelly to keep the wound moist, and then cover it with gauze or a bandage. Repeat this process daily until the wound heals. To reduce swelling, apply a cool, damp washcloth to the wound and keep the injured area elevated above the level of your heart.
To relieve pain and reduce swelling, you can take ibuprofen or acetaminophen. However, if you have a history of heart disease, high blood pressure, kidney disease, or stomach ulcers, consult a healthcare provider before taking these medications. Additionally, antibiotics may be prescribed to prevent infection.
For nail regrowth, it typically takes four to six months for a fingernail to fully regrow, and twice as long for toenails. This process can be expedited by consuming biotin, found in vegetables like spinach, and bone broth, which contains collagen.

Preventing nail damage
It takes around 4 to 6 months for a fingernail to fully regrow, and twice as long for toenails. The rate of growth also decreases with age. Here are some tips to prevent nail damage:
Keep Nails Short
Keeping your nails short can help prevent nail damage. Nails that are too long are more prone to breaking and tearing. Trimming your nails regularly can also help strengthen them.
Moisturize Nails Regularly
Moisturizing your nails, especially if you wash your hands frequently, can help prevent nail damage by keeping them healthy and hydrated. This can include drinking plenty of water to stay hydrated and prevent brittle nail beds.
Protect Nails During Activities
Wearing protective gear, such as gloves, when playing sports, cooking, or using cleaning products can help prevent nail damage. Choosing the right shoes can also help, as ill-fitting shoes can cause trauma to your nails.
Avoid Nail Biting and Picking
Nail biting and picking can cause nail damage and tear your nails. If you struggle with nail biting, you can try wearing socks or mittens to bed or coating your nails with a bitter substance like lemon juice or a nail-biting reducer nail polish.
Strengthen Nails with Nutrients
Consuming nutrient-rich foods such as spinach, eggs, olive oil, carrots, sweet potatoes, kale, milk, strawberries, broccoli, and seafood can help provide your body with the vitamins and minerals it needs to support nail health. You can also try taking supplements like biotin, which has been anecdotally reported to increase nail growth.

Speeding up nail growth
It takes anywhere from 3 to 6 months for a thumbnail to regrow, depending on your body. Here are some tips to speed up nail growth:
Nutrition
Eating a well-balanced diet rich in vitamins, minerals, and proteins can contribute to healthier and faster nail growth. Consume foods such as eggs, lean meats, fish, beans, nuts, leafy greens, and vegetables that provide essential nutrients for nail health. Biotin, a type of B vitamin, is highly recommended as a supplement to boost nail strength and growth. It can be found in vegetables like spinach. Bone broth, which contains collagen, can also help speed up nail growth.
Grooming and Maintenance
Regular nail grooming and maintenance can boost nail strength and encourage growth. Keep your nails dry and clean to prevent bacterial growth. Use sharp manicure scissors or clippers to trim your nails straight across, then round the tips into a soft curve. Avoid biting your nails or cutting them too short. Moisturize your hands and nails with lotion, paying special attention to the cuticles. Regularly massaging your nails and cuticles with nourishing oils like coconut oil, olive oil, or argan oil can also promote growth and strengthen your nails.
Nail Care
Painting your nails can help protect them and promote growth. Consider using a strengthening base coat or a strengthening polish to fortify your nails. However, be cautious with nail hardeners as they can make your nails brittle and more prone to breaking. Keep your nails filed and smooth to reduce the risk of breakage.
While there is no scientifically proven method to make nails grow faster, taking care of your body through proper nutrition and nail grooming techniques can help your nails grow strong and long over time.
