Toenails are protective plates found at the tip of the toes, corresponding to the claws in other animals. They are made of a tough rigid protein called alpha-keratin, which is also found in the horns and hooves of vertebrates. The nail consists of the nail plate, the nail matrix, and the nail bed. The nail matrix is the active tissue that generates cells, which harden as they move outward from the nail root to the nail plate. Toenails grow out of the matrix, a small pocket under the skin that constantly creates new cells, lengthening the nails and pushing old ones out. Toenails grow about half as fast as fingernails, taking 12 to 18 months to regrow completely.

What You'll Learn
Toenails grow from the matrix
Toenails are protective plates found at the tip of the toes, corresponding to the claws in other tetrapod animals. They are made of a tough, rigid protein called alpha-keratin, which is also found in the claws, hooves, and horns of vertebrates. The nail consists of the nail plate, the nail matrix, and the nail bed below it, with surrounding grooves.
The nail matrix, or matrix unguis, is the actively growing tissue, or germinal matrix, that generates cells. The nail grows out of the matrix, a small pocket that forms under the skin. The matrix constantly creates new cells, lengthening the nails and pushing the old ones out. As the cells move outward from the nail root to the nail plate, they harden. The nail plate, or nail body, is the visible hard nail area from the nail root to the free edge. It is made of translucent keratin protein and is strongly attached to the nail bed.
The nail root is the base of the nail underneath the skin and originates from the actively growing tissue of the matrix. The nail bed adds material to the underside of the nail to make it thicker. The cuticle is the waterproof barrier that lies between the nail plate and the skin of the toe. It protects the matrix from infection and can be maintained by moisturization and gentle pushing back with an orange wooden stick.
Toenails grow about half as fast as fingernails, with an average monthly growth rate of 1.6 mm compared to 3.5 mm for fingernails. Toenails take 12 to 18 months to regrow completely, while fingernails take only three to six months. Toenail growth can be stimulated by improving the keratin infrastructure, for example, by taking biotin supplements or using natural remedies with coconut oil or olive oil.

Toenails grow slower than fingernails
Several factors affect hair and nail growth, including season, gender, age, and heredity. For instance, hair and nails grow faster in the summer months than at any other time of the year. Men's hair and fingernails typically grow faster than women's, except during pregnancy and old age.
The difference in growth rate between fingernails and toenails may be due to their different uses and the resulting trauma to the nail bed. Nails evolved from claws about 55 million years ago and are one of the features that distinguish primates. While claws are ideal for gripping tree trunks, nails allowed for increased dexterity and precision. The evolution of nails from claws is important to the baseline rate of growth, but the difference in growth rates between fingernails and toenails may be equally dependent on nail use and trauma.
Increased forces on a nail bed can change the rate of nail growth. For example, the nails on an individual's non-dominant hand typically grow more slowly than the dominant hand, which is subject to more trauma. Similarly, toenails may grow more slowly because they are not used as much as fingers and fingernails. Toenails are also usually tucked away in socks and shoes, which may contribute to their slower growth rate.

Toenail growth can be stimulated
Toenails grow from the root, with the nail bed extending along the top of the last digit of the toe. They are made of densely packed keratin cells, a type of protein. Toenails grow more slowly than fingernails, but their growth rate is quicker in higher temperatures.
Additionally, moisturising your toenails daily with regular lotion can keep the surrounding skin soft and healthy. You can also use nail serums made from essential oils to prevent dryness, cracking, or brittleness. Taking biotin supplements has been proven to improve keratin infrastructure, helping you grow stronger nails faster. A balanced diet can also help your body produce healthy amounts of protein, supporting nail growth.
It is important to wear properly fitted shoes and socks to prevent toenail issues. Tight socks and ill-fitting shoes can restrict blood flow circulation, impacting nail growth. Toenails should also be regularly inspected and trimmed straight across to prevent ingrown toenails and bacterial infections.

Toenails protect toes from injury
Toenails are protective plates found at the tip of the toes, serving as a barrier to protect the toes from injury. They are made of a tough, rigid protein called alpha-keratin, which gives them strength and flexibility. The rate of toenail growth is approximately half that of fingernails, with toenails growing about 1.6 mm per month and taking 12 to 18 months to regrow completely.
The nail consists of several parts: the nail plate or nail body, which is the visible hard nail area; the nail matrix or nail root, which is the actively growing tissue underneath the nail plate; and the nail bed, which lies beneath the nail plate and contains nerves, lymph, and blood vessels. The nail plate is strongly attached to the nail bed and has grooves that help anchor it in place.
Toenails have essential functions beyond just protection from injury. They help us walk and maintain balance. Additionally, toenail health can provide insights into overall health and physiological imbalances. Changes in nail colour, thickness, brittleness, and other characteristics can indicate illnesses, nutrient deficiencies, or local injuries.
Proper toenail care is important to maintain foot health and comfort. Toenails should be trimmed regularly to prevent them from becoming too long and causing discomfort in shoes. Filing is also recommended to smoothen the nails and prevent tangling in cloth or other materials. Keeping the feet clean and dry can help prevent toenail infections, which can be caused by fungi, yeasts, or moulds. Ingrown toenails, a common issue, occur when the toenail presses into the skin on the sides of the toe and can be avoided by trimming the nails straight across instead of in a curve.

Toenail issues and infections
Toenails are protective barriers that safeguard our toes from injuries. However, these nails are susceptible to various issues and infections, which can cause discomfort and even lead to toenail loss. Here are some common toenail problems and ways to address them:
Ingrown Toenail
Ingrown toenails occur when the nail grows into the flesh on the sides of the toe. This can cause redness, warmth, swelling, and pain. Improper nail trimming, involving cutting nails with a curve instead of straight across, is a common cause of this issue. Wearing tight or narrow shoes can exacerbate the problem. To prevent and treat ingrown toenails, it is important to trim nails correctly and choose comfortable footwear.
Toenail Fungus
Fungal toenail infections, such as onychomycosis or tinea unguium, are incredibly common. They are caused by fungi, specifically dermatophytes, that grow between the toenail and the toenail bed. These fungi thrive in warm, moist, and dark environments, making feet an ideal place for them to flourish. Toenail fungus can be contracted from public areas like pools, locker rooms, and gyms. It often results in discolouration, thickening, and crumbling of the nail. While it may not be painful, it can be challenging to treat. Consulting a healthcare provider, such as a dermatologist or podiatrist, is essential for effective management.
Paronychia
Paronychia is an infection of the skin surrounding the nail, typically caused by bacteria. It can also be caused by viruses like herpes simplex or candida, a type of yeast. Symptoms include pain, redness, and pus. Soaking the affected toes in warm water several times a day can help, and in some cases, antibiotics or antiviral medications may be prescribed.
Trauma and Other Injuries
Trauma to the toenail or long-term inflammation, such as psoriasis, can also lead to toenail damage and pain. It is important to consult a healthcare professional for proper diagnosis and treatment.
Maintaining good foot hygiene, keeping your feet clean and dry, and choosing appropriate footwear are essential for preventing toenail issues and infections. If problems persist or become severe, seek medical advice from a qualified healthcare provider.
