What You'll Learn
Factors affecting nail growth rate
Fingernails grow at an average rate of about a tenth of a millimeter per day or 3.47 millimeters per month. However, several factors influence the rate of nail growth.
Firstly, the growth rate depends on which finger the nail is on. Studies have found that the little finger's nail grows slower than other fingernails, and the nails on the dominant hand and longer fingers grow faster. This could be due to increased blood circulation in the longer fingers and dominant hand. Additionally, nail growth rate varies with age. Dr William Bean observed that his thumbnail growth rate decreased from 0.123 mm per day at age 23 to 0.095 mm per day at age 67. This decline may be attributed to the slowing of blood circulation with age.
Hormone levels also play a role in nail growth rates. For example, pregnancy and puberty can lead to rapid nail growth due to fluctuating hormone levels. On the other hand, lactation and the balancing of hormones with age can decrease nail growth. Overall health and nutrition are other critical factors. Nutritional deficiencies can cause slow nail growth, and certain health conditions, such as peripheral artery disease, can reduce blood flow to the nails, slowing their growth.
Trauma to the nail can either slow or accelerate nail growth. Biting nails can stimulate circulation in the nail bed, leading to faster regrowth. However, injuries like pinching or dropping something heavy on the nail can damage the nail matrix, causing bruising, ridges, or nail loss. In such cases, proper medical care is necessary for the nail to regrow.
Genetics and hereditary factors also influence nail growth rates. While genetics determine the size and shape of nail beds, hereditary factors play a role in the actual growth rate. Lastly, external factors like the time of year and exercise level can impact nail growth. Nails tend to grow faster during the summer and daytime, possibly due to increased blood circulation.

How to strengthen nails
On average, fingernails grow about a tenth of a millimetre per day, but this can vary depending on factors such as age, hormone levels, overall health, and the finger on which the nail is located. For example, the nails on your dominant hand tend to grow faster, as do the nails on your longer fingers.
Take care of your body
Nutrient deficiencies may affect the appearance of your nails. Eating a nutrient-dense diet that is also high in protein can help improve nail health. Specific supplements such as biotin, collagen, and B vitamins have been recommended by some users, but it is important to consult a healthcare professional before taking any new supplements, especially if you take medication or have a chronic condition.
Stay hydrated
Drinking enough water is essential for nail health, but too much water can also be detrimental. Try to keep your hands out of the water when taking a bath, and wear gloves when washing dishes to avoid prolonged exposure to water.
Use nail care products
Nail hardeners and strengtheners can help reduce breakage and improve overall nail health. Oils such as jojoba oil, Dadi oil, and solar oil are recommended for use on the cuticles and underside of the nails.
Keep nails neatly trimmed
Maintaining neat and tidy nails can help prevent them from becoming torn or jagged, reducing the temptation to pick at or bite your nails. Nails can be a spot for germs to hide, and biting your nails can introduce these germs into your body, making you sick.
Protect your nails
When doing household chores, especially the dishes, it is recommended to wear gloves to protect your nails from harsh chemicals and prolonged exposure to water.

Protecting nails from damage
On average, fingernails grow about a tenth of a millimetre per day, but this can vary depending on factors such as age, hormone levels, overall health, and which hand or finger the nail is on. For example, the nails on your dominant hand tend to grow faster, and nails on longer fingers grow at a quicker rate.
Wear gloves
Protect your nails by wearing gloves when carrying out tasks that involve harsh chemical cleaners or water, such as washing dishes. This will help prevent breakage, peeling, and splitting.
Take biotin supplements
Biotin has been shown to reduce breakage and increase overall nail health. One 2007 study found that taking 2.5 milligrams of biotin daily improved nail strength.
Use nail hardeners sparingly
Nail hardeners may help strengthen nails and reduce breakage, but they should be used sparingly as overuse could potentially have negative effects.
Keep nails trimmed
Neatly trimmed nails are less likely to become torn or jagged. If your nails are not trimmed, you may be tempted to bite them, which can introduce germs into your body.
Skip cuticle cutting
The cuticle helps protect your nails and the surrounding skin from infection. Instead of cutting your cuticles, try gently pushing them back with a wooden stick.
Choose gel over acrylic nails
While gel nails can cause nail brittleness, peeling, and cracking, they are more flexible than acrylic nails, so your natural nails are less likely to crack. Ask for gel nails that can be soaked off, rather than filed off, and opt for an LED curing light instead of a UV curing light to reduce UV exposure.
Use natural oils and lotions
Daily use of natural oil, cuticle oil, or lotion can stimulate the recovery process if your nails have been damaged.

The role of cuticles
On average, fingernails grow about a tenth of a millimeter per day, but several factors influence this rate, such as the hand and finger, age, hormone levels, and overall health. Toenails, for instance, take thrice as long as fingernails to regrow.
Now, moving on to the role of cuticles:
The cuticle is a layer of clear or colourless skin located at the bottom edge of the nail bed, where the nail meets the skin. It is formed by the eponychium on the underside of the proximal nail fold, which is the skin that borders the bottom of the nail. Cuticles are composed of sticky dead skin cells that are shed by the living skin of the proximal nail fold. These dead skin cells are bound together by a sticky substance, adhering them to the emerging nail plate and the frame of the epidermis above.
The cuticle plays a protective role, guarding the new nails from bacteria and other invaders like pathogens, chemicals, and fungus spores as the nails grow out from the nail root. This protective seal is essential, as any interruption to the growth of the nail plate can slow or even stop nail growth. Cuticles also help keep the nails in place as they grow.
Cuticle care is important to maintain nail health. Soaking the hands or feet in warm water for about 10 minutes softens the cuticles and keeps the nails clean. Cuticle oil, massage cream, ointments, and Vaseline can also be used to moisturize and care for the cuticles, preventing dryness and cracking. While cutting the cuticles is a common practice in nail salons, it is not recommended by experts as it can increase the risk of infection and make the cuticles harder and more prone to fracturing. Instead, gently pushing back the cuticles with an orange stick or cuticle pusher is advised.

Tips for faster growth
On average, fingernails grow about a tenth of a millimetre per day, but this can vary depending on various factors, such as age, hormone levels, overall health, and nutrition. While there is no scientifically proven method to make nails grow faster, here are some tips to promote nail health and stronger, longer nails:
Tip 1: Hydration and Moisturization
Hydration is essential for nail health. Using a nourishing and hydrating hand cream can help maintain soft and supple skin, acting as a protective barrier against environmental stressors. Cuticle oils, such as vitamin E oil or plant-based oils, are also highly recommended to enhance nail health, prevent infections, and stimulate circulation.
Tip 2: Nutrition and Supplements
Proper nutrition plays a vital role in nail health. A well-balanced diet with adequate protein and vitamins is essential. Biotin, a type of B vitamin, is highly recommended as a supplement to strengthen nails and boost hair health. Folic acid (vitamin B9) is another important nutrient that supports cell growth and repair, promoting stronger and healthier nails.
Tip 3: Nail Care Techniques
The way you care for your nails can impact their strength and growth. Avoid using your nails as tools to open cans or scratch surfaces, as this can lead to tearing and breakage. When filing your nails, always file in one direction, using gentle, long, swift strokes, starting from the outside edge and moving towards the centre. This will give you a smooth finish and help achieve your desired shape.
Tip 4: Healthy Habits
Certain habits can hinder nail growth and health. Biting your nails or picking at the surrounding skin can introduce germs and bacteria, leading to potential infections. Additionally, excessive alcohol consumption and high refined sugar intake can negatively impact nail health. Reducing these habits and maintaining overall health can promote stronger and faster nail growth.
Tip 5: Protective Measures
Protecting your nails from external damage is crucial. Using a nail hardener can strengthen your nails, but it should be used sparingly as it may make nails too hard. BIAB (a type of nail treatment) can serve as "protective armour," providing a harder and more durable finish. It also has a less damaging removal process compared to other nail enhancements.
While these tips may not make your nails grow faster, they will help you achieve stronger and healthier nails that are less prone to breakage, allowing you to nurture and maintain longer nails.
