The shape and health of your nails can be influenced by a variety of factors, including genetics, lifestyle choices, and daily routines. While some people may be genetically predisposed to having strong, long nails, others may struggle with weak, brittle nails that are prone to splitting or peeling. In addition, certain nail shapes, such as the almond or coffin shape, are more durable and require less maintenance, while others, like the inverted triangle or sword shape, may need more frequent filing and reshaping to maintain their form. Understanding the natural shape and growth pattern of your nails is crucial when considering nail treatments, extensions, or manicures to ensure their longevity and avoid potential damage. Additionally, it is important to be aware of any changes in your nails, as they can sometimes indicate underlying health issues that require medical attention.

What You'll Learn
Genetic nail shapes
While there is limited information on the topic of genetic nail shapes, it is known that fingernail configuration is influenced by genetic factors, the shape of the distal phalangeal bone, mechanical forces, malnutrition, neurogenic factors, blood flow, and factors that cause the thinning and softening of nails.
There are primarily six nail bed types, and this will determine how long your nails can grow and how long gels and extensions will last. The most desired and long-lasting nail shape is vertically long and almond-shaped. This shape has long, straight sidewalls and a beautiful arch, providing the perfect amount of strength and natural support. With this shape, nail treatments, polish, gels, or nail extensions will grow out without distortion.
In contrast, sword-shaped nails, while easy to maintain, have a tendency to split at the sides or down the middle due to their genetic shape. They are also prone to peeling as they can easily get caught. For this reason, those with sword-shaped nails may opt for a gel overlay and regular treatments.
Inverted triangle-shaped nails tend to grow out and alter shape, meaning they can get snagged easily. This type of nail will need to be filed and reshaped regularly and will require gels, oils, and treatments as they tend to split horizontally.
In addition to genetic factors, fingernail shape and growth can be influenced by age, with the linear nail growth rate decreasing and the contour being modified with age, resulting in platonychia and koilonychia. The longitudinal ridges become more pronounced and numerous, and the colour varies from shades of yellow to grey. Furthermore, underlying diseases can alter the size of the fingernail, and the ratio between fingernail width and length is an important aesthetic criterion.

Natural nail care
While nail shape is often thought to be genetic, there are several other factors that influence nail health and growth. Natural nail care is important to achieve strong, healthy nails. Here are some tips for natural nail care:
Diet
Introducing the right vitamins and minerals into your diet is crucial for nail health. Vitamins and minerals contribute to nail cells' growth and strength. Include foods rich in vitamin B9, vitamin B12, iron, and magnesium in your diet. Vitamin B can be found in dark green vegetables, citrus fruits, meat, and eggs, while iron is abundant in meat, eggs, green leafy vegetables, beans, and peanuts. Magnesium, essential for protein synthesis, can also be included in the diet.
Nail Oils
Nail oils are essential for maintaining healthy nails. Natural oils rich in fatty acids and vitamin E can help moisturize, protect, and restore dry, brittle nails. Jojoba-based nail oils are particularly effective due to their small molecule size, allowing them to penetrate the nail plate easily and bond the layers of keratin together. Olive oil and coconut oil are other natural alternatives. A DIY nail treatment can be made by mixing equal parts of jojoba or olive oil with lemon juice, massaging it into the nails, and rinsing after 15 minutes.
Protect Nails from Water
Water is one of the worst chemicals for nails, as it can penetrate the nail plate and cause delamination or peeling. To protect your nails from water damage, it is recommended to wear gloves while cleaning, washing dishes, or even showering. However, it is still important to wash your hands regularly. Keeping your nails polished with a base coat can also help prevent water from entering the nail plate.
Filing and Clipping
To maintain the desired shape and length, regular filing and clipping are necessary. It is recommended to use a high-quality etched glass file, as they have a fine grit that won't damage your nails and last longer without dulling. When filing, use a gentle see-saw motion.
Moisturize
Moisturizing the nails and cuticles is crucial. Moisturizers such as olive oil or light hand lotion can help keep the nails and the surrounding skin hydrated and healthy.
Cuticle Care
Cuticle care is an important aspect of nail care. Cuticles are the thin layer of dead skin that seals the nail and skin. To soften cuticles and proximal nail folds, use a cuticle remover, such as Blue Cross or Sally Hansen brands.

Health conditions and nail clubbing
Nail clubbing is a condition where nails appear wider, swollen, and spongy, similar to an upside-down spoon. It is caused by soft tissue swelling of the terminal phalanx, resulting in a flattening or loss of the angle between the nail bed and the nail. While nail clubbing itself is usually painless and harmless, it is often an indicator of underlying health issues that require medical attention.
Nail clubbing is associated with a variety of health conditions, including cardiac, pulmonary, infectious, neoplastic, inflammatory, and vascular diseases. It is particularly linked to diseases of the heart and lungs, such as lung cancer, lung infections, interstitial lung disease, cystic fibrosis, and cardiovascular disease. In some cases, it can also be a sign of digestive conditions like Crohn's disease, celiac disease, or liver disease such as cirrhosis of the liver. Additionally, thyroid conditions such as hyperthyroidism and Grave's disease can lead to nail clubbing in certain individuals.
The treatment for nail clubbing focuses on addressing the underlying cause. For example, treatment plans may include chemotherapy, surgery, or radiation therapy for lung cancer. In cases of celiac disease, adopting a gluten-free diet can help manage the condition and improve nail clubbing. Heart surgery may be recommended for congenital heart conditions, and medications or surgery can treat hyperthyroidism.
While there is no known way to prevent nail clubbing, early detection and treatment of the underlying condition can help improve nail health and overall well-being. It is important to consult a healthcare provider if you notice any changes in your nails, as they can provide proper evaluation and guidance.

Nail technician damage
While there is a common misconception that nail technicians and nail products damage nails, this is not always the case. In fact, a qualified nail technician can save a client's nails from permanent damage that may occur from visiting an unqualified or poorly trained nail technician. However, there are instances where nail technicians have caused damage to clients' nails. For example, in the removal of shellac or gel polish, the use of an electric file can be too harsh and cut the skin around the nails and damage the nail beds, causing pain and discomfort.
Nail technicians themselves are also at risk of various health hazards in their day-to-day work. They can be exposed to chemical hazards from polishes, acrylics, and glues, as well as biological health hazards from blood and skin exposure. The "toxic trio" of chemicals commonly found in standard nail products—toluene, formaldehyde, and dibutyl phthalate—pose significant risks to the health of nail technicians. Toluene can cause dizziness, irritate the eyes, throat, and lungs, dry out or crack the skin, and damage the liver and kidneys. Formaldehyde, a known carcinogen, can irritate the eyes, skin, and throat and cause asthma-like symptoms. In addition, research has suggested a link between nail technicians working with UV light for gel manicures and cell damage.
Furthermore, nail technicians may suffer from musculoskeletal problems due to the repetitive and awkward postures required during work tasks, such as manicures and pedicures. To mitigate these risks, good ventilation and the use of gloves are recommended to reduce chemical exposures. Additionally, employing equipment that improves posture, such as adjustable chairs, and taking regular breaks can help prevent musculoskeletal issues.

Nail treatments
While the shape of your nails may be influenced by genetics, there are various nail treatments you can use to achieve your desired look.
French Manicure
The French manicure involves applying a pink base with white nail tips, intended to look natural and realistic. This treatment is also more durable than artificial nails. To achieve this look, a nail bed extension is custom-sculpted and applied to the natural nail. It is then filed down and finished with a top coat.
Paraffin Wax Treatment
Paraffin wax treatments are an add-on to a standard manicure or pedicure. This treatment involves dipping your hands, feet, and forearms into a tub of paraffin wax heated to 35°C. The wax is infused with botanical ingredients, such as aloe vera, azulene, chamomile, and tea tree oil, as well as fruit waxes from apples, peaches, and strawberries. Paraffin wax treatments can be particularly beneficial for those with fibromyalgia and arthritis, as they increase blood flow and relieve joint pain and inflammation.
Dip Powder Manicure
A dip powder manicure is a healthy alternative to traditional acrylic nails. Instead of using UV light, a sealant is applied after the base coat and dip powder. This method helps to achieve a smooth and even application and strengthens the nails with vitamins and calcium.
Classic Manicure
A classic manicure is a timeless treatment that focuses on enhancing the appearance of the nails and hands. It involves soaking the hands in warm water to soften the cuticles and nails, shaping and trimming the nails to the desired length and style, gently pushing back the cuticles, and removing any excess skin. After preparing the nails, a base coat is applied, followed by two coats of nail polish, each allowed to dry before the next. Finally, a top coat is added to seal and protect the colour, resulting in a glossy finish.
Hot Oil Manicure
A hot oil manicure is a nourishing and relaxing treatment for the hands, feet, and nails. It involves cleaning the cuticles and softening the skin.
Nail Care Products
In addition to these treatments, there are various nail care products available, such as cuticle oil, nail hardener, hand serum, and nail brightener. These products can help to strengthen, nourish, and enhance the appearance of your nails.
