What You'll Learn
Genetics and hormones
Genetics play a significant role in determining the size and shape of your nail beds, which in turn influences nail growth. There are six primary nail bed types, each with unique characteristics that affect how long your nails can grow and the durability of gels and extensions. For instance, rounded nails with gels or extensions tend to grow out faster due to their minimal sidewalls. On the other hand, sword-shaped nails are prone to splitting and peeling because of their genetic shape.
Hormones also play a crucial role in nail growth and overall nail health. Oestrogen, for example, helps nails grow strong and healthy by keeping water in body tissues. Thus, lower oestrogen levels can lead to dull and brittle nails. During pregnancy, when oestrogen and progesterone levels are exceptionally high, many women experience rapid nail growth. Additionally, testosterone is necessary for protein synthesis, particularly keratin, which is essential for healthy nails.
Hormones released during stressful events can also affect nail health. Dr Carl Pfeiffer found that about 30% of schizophrenia patients had white spots on their nails, indicating a drop in zinc caused by stress. Moreover, vertical lines on fingernails have been associated with a growth hormone deficiency and nutrient deficiency.
While genetics and hormones significantly impact nail growth, other factors come into play as well. For example, sun exposure is believed to increase nail growth, and nail biting or clipping can stimulate circulation in the nail bed, promoting faster growth.

Diet and nutrition
Protein is essential for nail growth as nails are made of a hard protein called keratin. Animal sources of protein such as eggs, chicken, turkey, lean beef, pork, and fish are rich in protein and zinc, both crucial for nail health. Vegetarian and vegan sources of protein include lentils, beans, peanuts, nuts, and dairy products. Lentils and beans are also excellent sources of iron and biotin, which help prevent anemia and are necessary for keratin formation.
Fatty acids are important for healthy cell development, which aids in nail growth. Omega-3 fatty acids, in particular, have been linked to improved nail health. Salmon, fatty fish, flaxseed, nuts, seeds, and avocados are good sources of omega-3 fatty acids.
Vitamins and minerals are also key to nail health. Vitamin D, found in eggs, salmon, and sunlight, helps regulate calcium levels, strengthening nails and bones. Biotin, a B-complex vitamin, promotes healthy cell growth and aids in the metabolism of protein-building amino acids, and can be found in eggs, salmon, liver, dairy, yeast, avocado, sweet potato, nuts, seeds, and cauliflower. Vitamin B12, found in salmon, meat, and dairy, is necessary for the development of healthy red blood cells and iron absorption. Iron is crucial, as a deficiency can lead to brittle or dented nails. Calcium, magnesium, and B vitamins are also important for nail health.
Finally, hydration is essential for nail health. Water aids in delivering nutrients and oxygen to the cells, and dehydration can lead to brittle, dry nails. Water-rich foods such as cucumbers, lettuce, celery, tomatoes, apples, and watermelon can also help with hydration.

Biotin supplements
While there are many factors that affect nail growth, such as age, gender, and diet, taking biotin supplements is a popular method for promoting nail growth and strength. Biotin, also known as vitamin B7, is a vitamin that helps the body convert food into energy. It is often recommended as a supplement to boost hair and nail health.
Several studies suggest that taking a biotin supplement daily can help strengthen nails and reduce breakage. For instance, a 2007 study found that taking 2.5 milligrams of biotin every day improved overall nail health. Similarly, a 2018 study by Lipner, S. R. investigated the use of biotin therapy for nail disorders. Furthermore, a 2023 study by Krabbe, J. P. reported that long-term raw egg consumption could lead to biotin deficiency, which can cause brittle nails. This suggests that taking biotin supplements may be beneficial for individuals with low biotin levels.
However, it is important to note that there is limited scientific evidence to support the widespread use of biotin for nail growth in otherwise healthy individuals. Most people get enough biotin through their diet, with sources such as fish and seeds being rich in biotin. Nevertheless, for individuals with brittle nails or those who want to boost their nail health, taking biotin supplements may be a safe option.
Overall, while biotin supplements may not be necessary for everyone, they can be a helpful tool for individuals looking to improve their nail health and promote stronger and faster-growing nails.

Nail care and grooming
While there are no proven methods to make your nails grow super fast in a week, there are some factors that affect the speed of nail growth. For instance, younger people tend to have faster-growing nails than older people, and men and pregnant women tend to experience faster nail growth than others. Nails on your dominant hand are also said to grow faster because you use that hand more, which increases the risk of trauma and sends more blood and nutrients to the nail area to help repair it.
Diet and Supplements
Your fingernails can reflect your overall health, and nutrient deficiencies may affect their appearance. A well-balanced diet full of fresh fruits and vegetables, lean proteins, carbohydrates, and healthy fats is essential for strong and healthy nails. Additionally, taking a biotin supplement of 2.5 milligrams daily can improve nail strength and overall health.
Nail Hardeners
Nail hardeners can be painted on like nail polish and help strengthen nails, reducing breakage. However, they should be used sparingly because prolonged use can break down the nail over time. Avoid products that contain formaldehyde or formalin.
Nail Grooming
Regular nail grooming and maintenance are crucial. Keep your nails clean and dry to prevent bacterial growth. Trim your nails regularly with sharp manicure scissors or clippers, cutting straight across and then rounding the tips into a soft curve. Avoid cutting your nails too short or pushing back or cutting your cuticles, as this can lead to infection.
Moisturizing
Moisturize your hands and nails with lotion, especially at the base of your nails where the cuticles are located. This is crucial during dry weather, as dry nails are more prone to splitting.
Avoid Nail Biting
Nail biting can increase the risk of nail breakage and infection. If you want longer nails, regular clipping is a better option.
Nail Care Kits
Investing in a nail care or manicure kit can be beneficial for nail grooming. These kits often include various tools such as nail clippers, scissors, files, and buffers, allowing you to maintain and care for your nails effectively.

Sun exposure and temperature
However, it is important to note that while sun exposure can promote nail growth, excessive sun exposure can also have negative effects on nail health. Sunburns, for example, can damage the skin and potentially impact the nails as well. Therefore, while enjoying the sun, it is crucial to take precautions such as wearing sunscreen and limiting direct sun exposure during peak hours to protect your skin and nails.
Temperature can also play a role in nail growth. In general, warmer temperatures can stimulate nail growth. This may be related to the increased blood flow and nutrient delivery to the nails in warmer conditions. However, it is important to note that extremely high temperatures can also have negative effects, such as causing dehydration and making nails more brittle.
Additionally, it is worth mentioning that the growth rate of nails can vary depending on the season. Nails tend to grow faster in the summer months when there is typically more sunlight and higher temperatures. This correlation between sun exposure, temperature, and nail growth highlights the complex interplay between environmental factors and nail health.
Overall, while sun exposure and warmer temperatures can contribute to faster nail growth, it is essential to maintain a balanced approach. Protecting your nails from excessive sun exposure and extreme temperatures is crucial for maintaining their health and promoting optimal growth.
