Nail cutting is an essential part of personal hygiene and self-care. While it is a simple task, it is easy to make mistakes that can lead to damaged or unhealthy nails. Cutting nails too short can lead to painful ingrown nails, which occur when the nail grows into the skin instead of over it. This can also increase the risk of infection, as the hyponychium—the skin underneath the fingernail—is exposed, and it is loaded with nerve endings. To avoid this, dermatologists recommend leaving 1-2 millimeters of the white rim of the nail when cutting them. This leaves the nails long enough to be functional while keeping them from getting in the way.

What You'll Learn
Short nails are less likely to harbour dirt and bacteria
Dermatologists recommend keeping nails short and well-manicured to prevent the buildup of dirt and bacteria, which can cause infections. Short nails are also less likely to break, which is good for both appearance and health. Additionally, trimming your nails can help detect early signs of health issues, such as fungal infections or skin diseases, allowing for timely treatment.
To properly trim your nails, it is recommended to soften them first by soaking them in lukewarm water for a few minutes. Then, use a nail clipper or nail scissors to cut almost straight across the nail. It is important not to cut the cuticles, as this can make it easier for bacteria and other germs to get inside the body and cause infections. Instead, leave the cuticles intact to protect the nail root.
After trimming, it is important to clean and disinfect the nail clippers to prevent the spread of bacteria. You can do this by soaking a small scrub brush in a bowl of 70-90% isopropyl alcohol and then using it to scrub the nail clippers. Rinse and dry the clippers before putting them away.
In addition to nail length, the shape of the nail can also affect how likely it is to harbour dirt and bacteria. Nails should be slightly rounded at the corners to keep them strong and prevent catching on things like clothing or furniture. Filing the nails in the same direction will help to keep them strong, as filing back and forth can weaken the nails.

Cutting nails too short can increase the risk of infection
Cutting nails too short can expose the hyponychium—the skin underneath the fingernail—which is loaded with nerve endings that are sensitive to touch. This can cause throbbing pain and increase the risk of infection.
The hyponychium is loaded with nerve endings, which are not designed to be exposed to the open environment. Cutting nails too short can leave the nail bed vulnerable to trauma and infection. In addition, the exposed area can invite bacteria and fungi, which can lead to a bacterial or fungal infection. Paronychia, a common nail infection, occurs when bacteria enter broken skin near the cuticle and nail fold.
To avoid infection, it is important to maintain nail hygiene. This includes keeping nails clean and washing and drying hands or feet before trimming. It is also recommended to cut nails straight across rather than at an angle and to avoid cutting too close to the skin. Additionally, using clean and sanitized nail clippers can help prevent infections.
Cutting nails too short can also lead to painful ingrown nails, which occur when the nail grows into the skin instead of over it. Ingrown nails can become infected, causing redness, swelling, and pain. In severe cases, medical attention may be required, including antibiotics or minor surgery.
To prevent cutting nails too short, it is recommended to only trim off the excess length and leave a small amount of white at the tip of the nail. This will help protect the nail bed and reduce the risk of infection.

Nails should extend past the finger pad to protect the hyponychium
The hyponychium is the thick skin located just under the free edge of the nail plate at the distal edge of the finger. It acts as a barrier to protect the nail unit from harmful substances, germs, debris, bacteria, allergens, and pathogens. The hyponychium is one of the four Guardian Seals of the nail unit, forming a tight seal with the onychodermal band to safeguard the delicate areas of the nail, such as the nail bed and matrix. This protective mechanism is enhanced by the presence of numerous nerve endings within the hyponychium, which serve as an alert system. When the seal is compromised, these nerve endings signal discomfort or pain, warning of potential damage or infection.
To maintain nail health and protect the hyponychium, it is essential to practice good nail hygiene. This includes regularly cleaning the nail area to keep it free from dirt and debris. Additionally, it is crucial to avoid activities that may cause trauma to the hyponychium, ensuring its integrity and functionality as a protective barrier. Cutting your nails too short can expose the hyponychium, leading to pain and an increased risk of infection. Therefore, it is recommended to leave 1-2 millimeters of the white rim (the lunula) of the nail when cutting them. This length allows the nails to be useful, such as when turning the pages of a book, while also preventing them from getting in the way during activities like typing.
Proper nail grooming techniques are important for maintaining nail health and protecting the hyponychium. It is recommended to soften the nails before trimming by soaking them in lukewarm water for a few minutes, especially after taking a bath or shower. When cutting your nails, it is best to use a nail clipper or nail scissors specifically designed for fingernails. Cut almost straight across the nail, avoiding cutting the cuticles, as they protect the nail root. Instead, use a nail file or emery board to slightly round the nails at the corners, helping to keep them strong and prevent them from catching on clothing or furniture.
In addition to proper trimming techniques, maintaining the health of the hyponychium and preventing infections can be supported by regularly cleaning and disinfecting nail care tools. This includes disinfecting nail clippers or nail scissors by soaking them in isopropyl alcohol and then rinsing them in hot water. It is also important to disinfect these tools after each use to prevent the spread of bacteria and fungi. By following these nail care practices, you can help ensure that your nails are not only aesthetically pleasing but also promote overall nail health and protect the hyponychium.

Clean nails and clippers to avoid transferring bacteria
Clean nails and clippers are essential to avoid transferring bacteria, fungi, and other microorganisms, which can lead to infections. Here are some tips to ensure proper nail and clipper hygiene:
Nail Hygiene:
- Keep your nails clean by regularly washing your hands and scrubbing under your nails to remove dirt and bacteria.
- Trim your nails regularly to prevent them from becoming overly long or prone to breakage. Use sanitized nail clippers or a nail file to achieve your desired nail length and shape.
- When trimming your nails, cut straight across to prevent ingrown nails. Then, use a nail file to smooth and round the corners, keeping them strong and preventing them from catching on things.
- Avoid cutting your cuticles. Cuticles protect the nail root, and cutting them makes it easier for bacteria and germs to enter and cause infections.
- Moisturize your nails and cuticles regularly to keep them hydrated and flexible, especially in dry conditions.
Clipper Hygiene:
- Disinfect your nail clippers regularly, ideally once a month, to prevent the buildup of bacteria, fungi, and other pathogens.
- To disinfect your clippers, disassemble them if possible. Then, soak the parts in a bowl of rubbing alcohol (isopropyl alcohol), hydrogen peroxide, or hospital-grade disinfectant for at least 5-30 minutes.
- Alternatively, scrub the clippers with a small brush soaked in 70-90% isopropyl alcohol or dab them with a cloth soaked in hydrogen peroxide.
- After soaking or scrubbing, rinse the clippers with warm water and dry them completely before storing them in a moisture- and dust-free environment.
- Always use your own nail clippers and avoid sharing them with others to prevent the spread of infections and diseases.
- Check your clippers regularly for any signs of rust, corrosion, or dull blades, as these can affect their effectiveness and increase the risk of uneven cuts and nail damage.
By following these nail and clipper hygiene practices, you can help maintain healthy nails and reduce the risk of transferring bacteria and other pathogens.

Moisturise nails and cuticles to prevent dry, brittle nails
While nail clipping is often done periodically without much thought, there is an optimal length for fingernails. Dermatologist Dr. Rajani Katta recommends leaving 1-2 millimetres of the white rim (the lunula) when cutting your nails. Nails that are too long can get ragged and torn, while nails that are cut too short can expose the hyponychium, the sensitive skin underneath the nail loaded with nerve endings. Cutting nails too short can also increase the risk of infection, especially ingrown nails, as bacteria and yeast can enter through the exposed skin or damaged cuticles.
To prevent dry, brittle nails, it is important to moisturise your nails and cuticles. Nails can dry out with age, losing the natural oils that hold the nail layers together. Exposure to harsh soaps, cleaning products, solvents, and rough work can exacerbate this. To combat dryness, use creams, oils, or ointments on your nails daily, especially after your nails have been wet. The best hydrating ingredients for nails include shea butter, jojoba oil, avocado oil, and other rich natural oils. Thicker creams and ointments are ideal, and oils can also provide effective relief.
Cosmetics companies have begun to address this issue, releasing treatments that claim to moisturise and nourish the nails and surrounding skin. Some products are polishes packed with vitamins and minerals, while others are supermoisturizers with ingredients like collagen, vitamin E, avocado oil, and shea butter. These products are designed to be massaged into the nails and cuticles.
In addition to moisturising, you can take other steps to prevent dry, brittle nails. When clipping and filing your nails, do so when they are wet, as clipping dry nails can worsen splitting. You can also wear gloves when handling harsh chemicals or doing rough work to protect your nails. Finally, consider supplementing your diet with vitamin supplements formulated for nail growth, such as those containing biotin, or focus on consuming whole foods rich in these nutrients, including fruits, vegetables, whole grains, nuts, natural oils, beans, and fish.
