What You'll Learn

Consume protein and biotin-rich foods
Consuming protein and biotin-rich foods is essential for achieving thick, strong, and long nails. Nails are made of proteins like fibrogen, so ensuring adequate protein intake is crucial for nail growth and strength. While a high protein intake may not guarantee stronger nails, a protein deficiency can lead to weaker nails. Animal proteins, such as meat, fish, and dairy, are excellent sources of protein and also provide zinc, which is necessary for healthy nail growth. Additionally, certain plant-based foods like nuts and soy products can also provide sufficient protein.
Biotin, also known as vitamin B8 or vitamin H, is an essential nutrient for nail health. It promotes healthy cell growth and aids in the metabolism of protein-building amino acids, which are crucial for nail growth. Biotin-rich foods include whole grains, bananas, avocados, eggs, dairy, nuts, seeds, and sweet potatoes. Organ meats, such as liver, are particularly rich in biotin. Consuming a variety of fruits, vegetables, nuts, and seeds, along with adequate protein and omega-3 fatty acids, will contribute to stronger and healthier nails.
Some people opt for protein supplements, powders, or drinks to increase their protein intake. While these may be beneficial for those with a low-protein diet, they may not significantly impact those who already consume sufficient protein through their regular diet. It is worth noting that excessive protein intake beyond what the body can absorb may not directly translate to stronger nails.
In addition to a nutrient-rich diet, regular moisturization is essential for maintaining nail health. Using nourishing and hydrating hand creams can help keep the skin and cuticles supple, preventing infection and promoting strong nail growth. Cuticle oils are also highly beneficial, as they provide deeper hydration and stimulate circulation, further promoting nail growth.

Use cuticle oil
Cuticle oil is an essential product for nail care. It can help to stimulate nail growth, promote stronger nails, and protect them from the elements. Cuticle oil can also help to prevent hangnails and stop the layers of the natural nail from peeling.
The cuticle is the nail's natural protective seal. When it becomes dry and dehydrated, it is compromised. This can cause redness and swelling, and eventually, the nail could grow irregularly. Therefore, it is important to keep the cuticles moisturized.
Applying cuticle oil can increase the circulation around your nails, and a massaging motion could help stimulate circulation and promote nail growth. Cuticle oil can also help to protect your nail and cuticle against trauma. It can also help improve the health and appearance of your nail.
There are many different cuticle oils on the market, so it is easy to find one that suits your needs. OPI's cuticle oil is formulated with rich ingredients such as avocado, grapeseed, and sunflower oils, and is super replenishing and soothing for nails and cuticles. Olive & June cuticle serum is also rich in moisturizing ingredients and is soothing to nails. It contains avocado oil, apricot oil, cactus flower extract, and jojoba oil to hydrate and stimulate nail growth. For a budget option, Sally Hansen Vitamin E Nail & Cuticle Oil is available for $8.

Moisturise regularly
Moisturising your nails and hands regularly is an essential step in achieving strong, long nails. Nails are made up of a protein called keratin, which is also found in hair and skin. A deficiency in protein may cause weaker nails, so it is important to ensure you are consuming enough protein in your diet. Nails also need to be moisturised from the outside, as dry, cracked skin and cuticles can lead to infection or weak nail growth.
Dr Dana Stern, a board-certified dermatologist, explains that the cuticle is the nail's natural protective seal. When it becomes dry and dehydrated, water and moisture can enter the nail unit, causing problems such as redness and swelling, and potentially causing the nail to grow irregularly. Therefore, it is important to keep the cuticle moisturised and healthy.
Using a nourishing and hydrating hand cream can help to maintain nail health. Streets, a beauty journalist, recommends Aveeno Daily Moisturising Hand Cream for fast hydration without a sticky feel, and L’Occitane Shea Butter Hand Cream for very dry hands. Streets also advises that you use a massaging motion when applying hand cream, which can help stimulate circulation and promote nail growth.
Cuticle oils are another way to moisturise your nails and promote nail growth. These can be applied at night to give the oil time to absorb. Streets and Dr Dana recommend using a single drop on each cuticle, and massaging it in to stimulate circulation. Cuticle oils can provide deeper hydration than hand creams, and can also act as a protective barrier against environmental stressors, such as cold weather.

Avoid harsh chemicals
To grow thick, strong, and long nails, it is important to avoid harsh chemicals. Nails are delicate, and exposure to certain chemicals can cause damage and breakage. Here are some tips to avoid harsh chemicals and promote healthy nail growth:
Firstly, opt for chemical-free lotions and creams to keep your hands and nails moisturized. Dry and dehydrated cuticles can lead to weak nail growth and infections. Look for nourishing and hydrating hand creams that create a protective barrier for your nails and hands.
Next, be mindful of the nail polish and nail polish removers you use. Traditional nail polishes and removers often contain harsh chemicals such as acetone, butyl acetate, and dibutyl phthalate (DBP). These chemicals can cause irritation to the eyes, skin, nose, mouth, and throat. Instead, opt for non-toxic, five-free, or seven-free nail polishes and removers, which are free from common harsh chemicals. These alternatives may be healthier options, although specific health benefits may vary. Additionally, gel manicures involve curing nail polish under a lamp, which emits ultraviolet A light known to cause cellular damage and increase the risk of skin cancer. If you choose to get gel manicures, consider using alternative lamps that emit LED light, although they may still emit some UV light.
It is also important to be cautious when visiting nail salons. Nail salon workers are exposed to various chemicals daily, and poor ventilation can increase the risk of adverse health effects. Choose salons with proper ventilation systems and exhaust fans to minimize chemical exposure. Additionally, look for salons that use less toxic products and participate in healthy workplace initiatives. These salons are recognized for their commitment to using safer, less toxic polishes and nail care products.
Finally, be mindful of the products you use at home for nail care. Artificial nails, nail primers, and nail glue removers can contain chemicals like methyl methacrylate monomer, acetonitrile, and ethyl acetate. These chemicals have been associated with allergic reactions, contact dermatitis, and other adverse health effects. Always read the ingredient labels and opt for safer alternatives whenever possible.
By avoiding harsh chemicals and choosing safer alternatives, you can promote healthy nail growth and minimize the risk of damage and adverse health effects.

File nails correctly
Filing your nails is a good way to keep them at a uniform length and shape, and it can prevent them from breaking. However, it is easy to file your nails incorrectly, which can lead to jagged, frayed nails and even nail bed or cuticle damage.
Firstly, it is important to have the right tools. You will need fingernail clippers, a nail file (a classic emery board or a glass file, which is gentler on the nails and easier to clean), and a nail oil and cuticle oil to help repair frayed nails and prevent future breakage.
Before you start filing, cut your nails to the desired length. Then, file your nails in one direction, from the outer corner into the centre of the nail, and repeat the motion on the other side. Filing in one direction blends the layers of your nails and promotes growth. Filing back and forth like a saw can weaken your nails and cause the layers to split.
Go easy on the sides of your nails, as filing too much can weaken them. It is best to work with your natural nail shape, which is typically either round or square, and is determined by the shape of your cuticle and nail bed.
