Nail growth rate factors
Fingernails grow, on average, about a tenth of a millimeter per day, but several factors can influence this rate of growth.
Age
The growth rate of nails decreases as people age. Dr William Bean observed that his left thumbnail grew at a rate of 0.123 mm per day when he was 23 years old. By the time he was 67, this rate had dropped to 0.095 mm per day. This change in speed may be because blood circulation slows with age.
Hand
The nails on the dominant hand tend to grow faster. Additionally, the nails on the longer fingers grow faster than those on the shorter fingers. For example, the little finger's nail grows slower than the other fingernails.
Season
Nails grow faster during the summer.
Time of day
Nails grow faster during the day.
Hormone levels
Hormone levels can also affect nail growth rates. For example, nail growth is said to peak during puberty and decline as hormone levels balance out with age. Pregnancy also affects nail growth rates, increasing growth during pregnancy and decreasing it during lactation.
Overall health and nutrition
Nutritional deficiencies or underlying health conditions can cause nails to grow unusually slowly or experience discolouration. Ensuring proper nutrition and addressing any health issues can help maintain healthy nail growth.
Nail care
Practising good nail hygiene and care can help maintain healthy nails and promote growth. This includes keeping nails clean, trimming them regularly, and moisturising the cuticles. Using nail/cuticle oil can help strengthen nails and prevent breakage. Additionally, using a glass nail file instead of clippers can help achieve longer nails.

Prevent nail breakage
Growing long nails is not an easy feat. Fingernails grow on average about a tenth of a millimeter per day, and there are many factors that can affect this rate, including age, hormone levels, and overall health. Here are some tips to prevent nail breakage while growing out your nails:
Keep Them Moisturized
Just like your skin, your nails need hydration too. Dry nails are more prone to breakage, so make sure to moisturize your hands and nails regularly. You can use a good quality hand cream, nail lotion, or cuticle oil to keep them hydrated. Coconut oil can help treat cracked and brittle nails and is also a natural anti-inflammatory, which is great if your cuticles are irritated or inflamed.
Nail-Friendly Diet
Your diet plays a significant role in the health of your nails. Incorporate foods rich in biotin, vitamin E, and omega-3 fatty acids into your meals. Think eggs, nuts, avocados, and salmon. These nutrients promote nail strength and growth. Drinking enough water throughout the day is also important for nail health.
Avoid Harsh Chemicals
Be mindful of the products you use on your nails. Harsh chemicals in nail polish removers and cleaning products can weaken your nails. Opt for acetone-free nail polish removers and always use gloves while doing household chores involving harsh chemicals or water. Water is the worst possible chemical for your nails, so it is important to limit water exposure.
Gentle Handling
Treat your nails with care and avoid using them as tools for tasks like opening cans or scratching off stickers. Long nails are more likely to break and be caught on things, so be mindful of this when performing daily tasks.
Groom Your Nails
Keeping your nails clean is key to overall nail health. Use a clean pair of clippers to trim them regularly and file them in one direction, going easy on the sides of the nails since filing too much can weaken the nails.

Nail growth supplements
On average, fingernails grow about a tenth of a millimetre per day, but this can be affected by factors such as age, hormone levels, and overall health. For example, nail growth peaks during puberty and slows down as hormone levels stabilise with age. Additionally, nails grow faster during the day and in the summer.
While consuming a nutrient-rich diet is the best way to achieve strong and healthy nails, certain supplements may help support nail growth and strength. Here are some key considerations regarding nail growth supplements:
Biotin Supplements: Biotin, also known as vitamin B7, is one of the most popular supplements for nail growth. While biotin deficiency is rare, consuming biotin through supplements or diet can help strengthen brittle nails and improve their growth. A 2007 study found that taking 2.5 milligrams of biotin daily reduced nail breakage and improved overall nail health. However, it is important to note that biotin supplements can sometimes exacerbate skin issues, as reported by some users.
Vitamin B12 and Folate: Vitamin B12 and folate (vitamin B9) are also important for nail health. Both vitamins play a role in red blood cell formation and the development of new cells. A deficiency in either vitamin can lead to nail discolouration and brittleness. Therefore, ensuring adequate intake through diet or supplements can support nail health and growth.
Zinc Supplements: Zinc is essential for the healthy growth of nails. Animal proteins are a great source of zinc, but it can also be found in certain plant foods. While including zinc-rich foods in your diet is ideal, taking a zinc supplement can help meet your requirements and support nail growth if dietary intake is insufficient.
Nail Hardeners: While not typically considered a supplement, nail hardeners can be applied topically to strengthen nails and reduce breakage. However, prolonged use of nail hardeners is not recommended as they can break down the nail over time. It is also important to avoid products containing formaldehyde or formalin.
Overall, while supplements can provide a boost, maintaining a healthy and balanced diet that includes a variety of fruits, vegetables, nuts, seeds, and adequate protein and omega-3 fatty acids is the best way to support nail growth and overall nail health. Additionally, practising good nail hygiene, such as regular grooming and moisturising with cuticle oil, can help keep your nails strong and promote growth.

Nail grooming tips
Fingernails grow at an average rate of about a tenth of a millimeter per day or approximately 3.47 millimeters per month. However, there are several factors that can influence this rate, such as age, hormone levels, overall health, and dominant hand. For example, nails tend to grow faster during the day and in the summer, and the nails on the dominant hand typically grow quicker. Additionally, nail growth peaks during puberty and gradually slows down as hormone levels stabilize with age.
- Practice good nail hygiene: Keep your nails clean and well-maintained. Use a gentle nail file sparingly to shape your nails and avoid excessive buffing or cuticle cutting. Glass nail files are recommended as they do not dull over time and have a fine grit that won't damage your nails.
- Moisturize and nourish your nails: Apply cuticle oil or nourishing oils such as coconut oil, olive oil, or argan oil regularly to promote nail growth and strengthen your nails. This helps to keep your nails hydrated, flexible, and less prone to breakage.
- Take supplements: Consider taking biotin supplements, which have been shown to reduce nail breakage and improve overall nail health. Keratin supplements, either oral or topical, can also help strengthen nails and promote resiliency.
- Maintain a balanced diet: Consume a diet rich in vitamins, minerals, and proteins. Include foods such as eggs, lean meats, fish, beans, nuts, and leafy greens to provide essential nutrients for nail health. A healthy diet contributes to healthier and faster nail growth.
- Protect your nails: Avoid prolonged exposure to water as it can be damaging to your nails. Wear gloves when washing dishes or cleaning, and consider using a base coat or nail polish to create a protective barrier. Additionally, avoid glue-on nails and toxic nail polishes, opting instead for nontoxic or water-based alternatives.
- Trim and groom regularly: Regularly trim your nails to prevent snagging and reduce the risk of breakage. Use a clean pair of clippers, and avoid cutting your cuticles. Push back your cuticles instead, and consider using a cuticle remover if needed.
- Use nail strengtheners: Apply dermatologist-approved nail strengtheners or hardeners sparingly to protect and fortify your nails, reducing the chances of breakage. However, avoid prolonged use, and choose products that do not contain formaldehyde or formalin.
- Be mindful of health conditions: Monitor your nails closely if you have diabetes or circulatory issues, as these conditions can affect nail growth and recovery from nail disorders. If you notice any unusual symptoms or changes in your nails, consult a doctor to address any potential nutritional deficiencies or underlying conditions.
By following these nail grooming tips, you can promote healthy nail growth and maintain strong, beautiful nails.

Nail growth oils
On average, fingernails grow about a tenth of a millimeter per day, but this rate can vary depending on factors such as age, hormone levels, and overall health. While you cannot control all of these factors, maintaining good nail hygiene can help promote nail growth. This includes keeping your nails clean and using a glass nail file instead of clippers to avoid damaging your nails.
In addition to hygiene, using nail growth oils can be beneficial. These oils are designed to moisturize, strengthen, and promote the growth of your nails. Here are some specific tips and product recommendations for nail growth oils:
Tips for Using Nail Growth Oils:
- Jojoba-based oils are highly recommended due to their molecular similarity to the body's natural oils. This allows the oil to penetrate through the nail plate for deeper absorption, helping to keep the layers of keratin bonded and reducing peeling.
- Vitamin B7 (Biotin) is essential for nail growth as it promotes healthy cell growth and aids in the metabolism of protein-building amino acids. Look for nail growth oils that contain this vitamin.
- Vitamins E and C are also beneficial as they strengthen nails and reduce breakage. Vitamin E provides deep hydration without a greasy feel.
- Massage the oil into your cuticles and nail beds daily or nightly before bed for optimal results.
Product Recommendations:
- Radiant Cosmetics' Organic Nail Growth Oil is a 100% organic formula designed to moisturize, strengthen, and promote nail growth. It contains vitamins B7, E, and C, as well as fatty acids for deep hydration.
- Twinkled T's Organic Nail Honey Cuticle Oil is formulated with nourishing organic oils to strengthen thin, damaged nails and promote growth. It is recommended to apply this oil twice daily, especially after washing your hands.
- OPI Nail Envy is mentioned by a user as helping to grow out their nails. However, they also mention taking a break from using it after one or two weeks to prevent nails from becoming too hard and brittle.
Remember, while using nail growth oils can be beneficial, it is also important to maintain overall nail hygiene and health. Consult with a doctor if you notice any unusual symptoms, as nail growth can be affected by nutritional deficiencies or underlying health conditions.
