To strengthen your nails, you can take a biotin supplement, drink more water, eat a nutrient-dense and protein-rich diet, and use nail lotions and oils. You can also moisturize your nails with hand cream and natural oils like jojoba, coconut, flaxseed, and rosehip carrier oils. It is also important to be mindful of harmful chemicals in nail products and opt for non-toxic alternatives.

What You'll Learn

Moisturise your nails with hand cream or natural oils like jojoba, coconut, or olive oil
One way to strengthen your nails is to moisturise them with hand cream or natural oils like jojoba, coconut, or olive oil.
Hand Cream
Applying hand cream to your nails is a simple way to moisturise them. You can use your regular hand cream for this purpose. It is recommended to apply the cream after exfoliating your nails, and then to seal in the moisture with an ointment such as Vaseline or Aquaphor. You can also wear gloves to further lock in the moisture.
Coconut Oil
Coconut oil is a versatile natural ingredient that can be used to moisturise your nails and cuticles. It is rich in fatty acids, which act as a barrier to prevent transepidermal water loss. To use, simply rub coconut oil onto your cuticles and let it penetrate for at least 30 minutes. You can leave it on for longer, or even overnight, for better results.
Jojoba Oil
Jojoba oil is an effective natural emollient that can deeply hydrate your nails and the surrounding skin. It is quickly absorbed due to its small particle size, and it helps to lock in moisture. To use, apply a few drops of jojoba oil above your nails and around the cuticle area, especially after washing your hands with warm water.
Olive Oil
Olive oil is a natural way to strengthen and moisturise your nails. It helps to repair damage, soften the nails, and promote nail growth. You can apply it directly to your nails and cuticles, or soak your fingertips in warm olive oil for 15 to 20 minutes. Then, dry your hands naturally and cover them with gloves overnight.

Take a biotin supplement
Biotin, also known as vitamin H, vitamin B7, and vitamin B, is a water-soluble vitamin that supports nail strength and health. It is made up of protein and amino acids, which promote keratin production in the body. Keratin is a type of protein that forms the cells that make up the tissue in nails.
Biotin supplements may help strengthen weak or brittle nails. According to a Swiss study, patients with brittle nails who took biotin supplements showed a 25% increase in nail plate thickness. Out of thirty-five patients who took daily biotin supplements, twenty-two (63%) showed clinical improvement.
The daily recommended intake of biotin for adults is 30 to 100 mcg. However, it may take some time to see results, as nails naturally regenerate every 4-6 months. It could take anywhere from 6-12 months for regular biotin supplementation to support nail growth.
Biotin-rich foods include egg yolks, nuts, milk, grains, salmon, cauliflower, sweet potatoes, seeds, broccoli, and mushrooms. However, if you are considering taking biotin supplements, it is important to consult with a healthcare professional, especially if you are taking medications or have a chronic condition.

Eat a nutrient-dense diet with plenty of protein
Eating a nutrient-dense diet with plenty of protein is essential for maintaining strong and healthy nails. Nails are made of a protein called keratin, which also forms the cells of your hair and skin. Keratin provides structure, strength, and resilience to your nails, protecting them from damage.
To ensure your body has sufficient keratin, include various protein sources in your diet, such as lean meats, fish, eggs, dairy, beans, and nuts. These foods provide the amino acids necessary for keratin production. Additionally, consider consuming collagen-rich foods like bone broth, egg whites, and citrus fruits, as collagen is another vital protein for nail health.
While protein is crucial, don't forget the importance of trace minerals and vitamins. Aim for 7-10 cups of nutrient-dense, mineral-rich vegetables daily. Include colourful options like dark, leafy greens, bell peppers, carrots, and beets. These provide the minerals required for protein synthesis and overall nail health.
If you feel you're not getting enough nutrients from your diet, consider taking supplements. Biotin, also known as vitamin H or B7, is a water-soluble vitamin that promotes nail strength. Vitamin C, vitamin A, amino acids, and omega-3 fatty acids are also beneficial for nail health.
Remember, maintaining healthy nails involves more than just diet. Be mindful of your day-to-day activities, and avoid using your nails as tools to prevent breakage and chipping. Keep your nails moisturized and well-hydrated, and be cautious when filing and trimming to avoid weakening the nails.

Avoid using your nails as tools
To make your fingernails hard and strong, it is important to avoid using your nails as tools. Nails are primarily designed to protect your fingers, and using them as tools can lead to breakage and chipping, which can weaken the nail.
Use appropriate tools
When you find yourself reaching for something or trying to open a package, pause and consider if there is a better tool for the job. For example, use nail clippers or manicure scissors to cut off tags or open packages. A simple rubber band can help you open a stubborn twist-cap bottle. Just wrap it around the top a few times to create some friction when you twist it by hand. You can also use a paper clip to reach something in a small space instead of your nails.
Be mindful of your habits
If you find yourself using your nails out of habit, try to be more mindful and catch yourself before you start. If you struggle with nail-biting, try chewing gum to keep your teeth busy, making it less likely that you'll bite your nails.
Protect your nails
If you work with your hands or are often doing manual work, consider using gloves to protect your nails from breaking. You can also use a comb or a scalp massager instead of your nails when washing your hair.
Keep your nails trimmed and well-maintained
Keeping your nails short can help prevent breakage and also gives them time to build up strength. After trimming, file your nails gently in one direction only, as filing back and forth can weaken them.
By following these tips and being mindful of how you use your nails, you can avoid using them as tools and help keep them strong and healthy.

File your nails gently in one direction
To make your fingernails hard, you can take biotin supplements, drink enough water, eat a nutrient-dense and high-protein diet, and use nail lotions and oils. You should also take care when filing your nails. Filing your nails in a back-and-forth motion can weaken them and cause damage to the nail tip, leaving them feeling sharp and jagged. Instead, file your nails gently in one direction only. This helps to even out the surface, leaving your nails with a smooth and rounded finish. Glass, diamond, and crystal files are recommended for their softer edge. However, one source claims that the direction of filing does not matter and will not cause additional nail damage.
