What You'll Learn
Genetics and hormones
While there are no scientifically proven methods to make nails grow faster, there are several factors that can influence nail growth, including genetics and hormones.
Genetics
The shape of your nails is largely determined by your genetics, and this can affect how long your nails can grow and how prone they are to breakage. There are primarily six nail bed types, each with its own unique characteristics and growth potential. For example, rounded nails tend to grow out faster as they lack significant sidewalls to maintain their shape. On the other hand, sword-shaped nails are prone to splitting and peeling due to their genetic shape.
Hormones
Hormones play a crucial role in nail growth and health. Oestrogen, for instance, helps keep water in body tissues, so lower oestrogen levels can lead to dull and brittle nails. During pregnancy, when oestrogen and progesterone levels are high, many women experience rapid nail growth. Conversely, lower oestrogen levels during menopause or postpartum can affect nail health, leading to dry and brittle nails. Additionally, testosterone is necessary for protein synthesis, specifically keratin, which is essential for nail growth.
Hormonal imbalances can also impact nail health. For example, a deficiency in growth hormone may manifest as vertical lines on fingernails. Parathyroid hormone regulates calcium and vitamin D levels, and a deficiency can result in brittle nails, which can be remedied by supplementing with calcium and vitamin D. Stress can also influence nail health, as evident by the appearance of white spots on fingernails, indicating a drop in zinc levels caused by stressful events.

Nutrition
While there are no scientifically proven methods to make nails grow faster, a well-balanced diet can improve the health of your nails, making them stronger and less prone to breakage. Nails are made of protein, so consuming an adequate amount of protein in your diet is important for nail health. A 2019 study also found a link between nail health and certain amino acids called collagen peptides, which some proteins contain. Foods such as eggs, chicken, turkey, lean beef, pork, and fish are rich sources of protein. For vegetarians and vegans, protein sources include lentils, peanuts, nuts, and dairy products.
In addition to protein, vitamins and minerals are essential for nail growth. Include a variety of nutrient-rich foods in your diet, such as eggs, nuts, seeds, and legumes, which contain vitamins A and D, zinc, and iron. Calcium is another important mineral for nail health, and supplements containing both calcium and vitamin D are preferable.
Biotin, a B-complex vitamin, has been found to improve overall nail health and reduce breakage. While there is limited evidence that biotin supplements will help nails grow faster, they have been shown to increase nail strength and prevent breakage, allowing nails to grow longer.
Hormones also play a role in nail growth regulation. For example, during pregnancy, increased estrogen levels can lead to faster nail growth, while a decrease in estrogen during menopause corresponds with a slowed nail growth rate. Additionally, individuals with certain conditions, such as hyperthyroidism, anemia, or diabetes, may experience faster nail growth, while those with psoriasis may have a slowed nail growth rate.
Environmental factors, such as temperature and climate, can also affect nail growth. Warmer climates tend to promote faster nail growth due to increased blood circulation, which delivers essential nutrients to the nail matrix. Maintaining a good nail care routine, including keeping your nails clean and well-maintained, can also help prevent breakage and encourage longer nails.

Blood circulation
Several factors influence nail growth, including genetics, overall health, age, nutrition, hormones, and blood circulation. As blood circulation slows with age, older adults tend to experience slower nail growth compared to younger individuals.
To increase blood circulation and promote nail growth, consider the following:
- Engage in cardiovascular exercises such as running, biking, or walking. Stretching before and after exercising can also boost circulation.
- Quit smoking if you smoke, as it inhibits blood flow and damages blood vessels.
- Consume antioxidant-rich beverages like black or green tea to increase blood vessel width, facilitating easier blood flow.
- Address any nutrient deficiencies, especially biotin, protein, and vitamin deficiencies, by adopting a balanced diet or taking supplements.
- Wear compression socks, especially when standing for extended periods, to aid in blood circulation back to the heart.
- Elevate your legs to facilitate blood flow to the upper body.
- Maintain a healthy scalp and promote blood circulation with essential oils like lavender, thyme, rosemary, cedarwood, and peppermint.
By improving blood circulation and overall health, you can support the growth of strong and healthy thumbnails.

Trauma
If your thumbnail sustains trauma, your body will naturally send more blood and nutrients to the area to aid in its repair, which may speed up nail growth. However, if your nail lifts completely off the nail bed, it will not reattach, and a new nail will have to regrow. This can take several months, and the time frame depends on various factors, including your age. For example, a 76-year-old man's thumbnail took nine months to regrow after a surgical avulsion, while another case study reported a range of five to ten months for fingernail regrowth.
To promote thumbnail regrowth after trauma, you can take specific measures. If your nail has lifted off the nail bed, you can initially replace the nail and hold it in place with a bandage for comfort. If there is bleeding under the nail, have a physician evaluate it to rule out any underlying issues such as bone fractures or tissue tears. Keep your tetanus vaccination up to date if you experience a nail injury.
Additionally, you can take steps to improve the overall health of your nails to prevent breakage and enable them to grow longer. Taking 2.5 milligrams of biotin daily has been shown to improve nail health and reduce breakage. Using nail hardeners sparingly can also strengthen your nails, but prolonged use may break them down over time, so avoid strengtheners with formaldehyde or formalin. Avoid glue-on nails and toxic polishes, opting for nontoxic or water-based alternatives instead.

Nail care
While there are no scientifically proven methods to make your thumbnails grow faster, there are several ways to increase the overall health of your nails, which can help them grow stronger and longer. Here are some tips for nail care to help you achieve healthier thumbnails:
Nutrition
Eating a balanced diet rich in essential nutrients can promote nail growth. Include foods in your diet that contain protein, biotin, vitamins A and D, zinc, and iron. Examples of such foods are eggs, nuts, seeds, and legumes.
Hormones
Hormones play a crucial role in regulating nail growth. For example, during pregnancy, increased estrogen levels can lead to faster nail growth. On the other hand, a decrease in estrogen levels during menopause can slow down nail growth. If you have a condition that affects your hormones, such as hyperthyroidism, anemia, or diabetes, this may also impact your nail growth rate.
Blood Circulation
Good blood circulation is essential for nail growth, as it delivers vital nutrients to the nail matrix. You can improve circulation by increasing blood flow through exercise or spending time in warmer climates. Additionally, the nails on your dominant hand tend to grow faster due to increased blood circulation from frequent use.
Maintaining a regular nail care routine can help prevent breakage and promote longer nail growth. Keep your nails clean and well-maintained by regularly filing and trimming them. You can also take supplements like biotin to strengthen your nails and reduce breakage. However, avoid prolonged use of nail hardeners, and limit or avoid those that contain formaldehyde or formalin.
Avoid Trauma
Try to avoid biting your nails or any activities that may cause trauma to your thumbnails. While nail biting can stimulate circulation in the nail bed, leading to faster growth, it also carries risks of infection and damage. Instead, opt for regular clipping or filing to maintain healthy nail growth.
By following these nail care tips, you can promote healthier and stronger thumbnail growth, even though there is no guaranteed method to make them grow faster.
