Hangnails are small, torn pieces of skin that peel away from the edge of your nail fold. They happen when the skin around your nails dries out, gets damaged, or loses its natural oils. Despite the name, hangnails aren’t related to the nail itself. They’re purely a skin issue, and the causes are almost always environmental or behavioral.
Dry Skin Is the Most Common Cause
The skin around your nails is thinner than most of the skin on your hands, and it has no oil glands of its own. It relies on moisture from the surrounding tissue and whatever oils it picks up through contact. When that skin dries out, it becomes stiff and brittle. Instead of flexing with your fingers as you move through the day, it cracks and separates, creating those sharp little flaps of skin.
Several everyday situations accelerate this drying process. Frequent handwashing strips natural oils from the skin. So does exposure to cold, dry air during winter months, which is why hangnails tend to spike in colder seasons. Working with paper, cardboard, or cleaning products can also pull moisture out of the nail fold skin repeatedly throughout the day. If you swim regularly in chlorinated water or use alcohol-based hand sanitizers often, the effect compounds.
Nail Biting and Skin Picking
People who bite their nails or pick at the skin around them are significantly more likely to get hangnails. Biting and picking create tiny tears in the nail fold that wouldn’t happen on their own. Once that skin is torn, it tends to peel further rather than heal flat, which is how a small bit of damage turns into a painful, persistent hangnail.
The bigger risk here is infection. Tearing the skin can cause further damage at the base of the nail and opens a direct path for bacteria to enter the cuticle area. An infected hangnail (called a paronychia) becomes red, swollen, and sometimes filled with pus. It’s a common reason people end up needing medical attention for something that started as a minor annoyance.
Chemical and Physical Irritants
Certain products and materials dry out or irritate the nail fold skin enough to trigger hangnails on their own. Acetone-based nail polish removers are one of the most common culprits. They dissolve polish effectively but also strip oils from the surrounding skin. Harsh soaps, household cleaners, and detergents have a similar effect, especially with repeated exposure over days or weeks.
Gel and acrylic manicures can also contribute. The removal process for these products often involves soaking in acetone or mechanical filing near the cuticle, both of which weaken the skin barrier. Even aggressive cuticle pushing or trimming during a standard manicure can create micro-tears that develop into hangnails.
Skin Conditions That Affect the Nail Fold
Chronic skin conditions can make the area around your nails more vulnerable. Psoriasis is one notable example. Nail fold psoriasis, which shows up as redness and flaky scaling around the nail edges, affects roughly 25% of people with nail psoriasis. That ongoing inflammation weakens the skin barrier and makes it far more prone to cracking and peeling.
Eczema (atopic dermatitis) on the hands has a similar effect. When the skin around your nails is already inflamed, itchy, and compromised, hangnails become a recurring problem rather than an occasional one. Contact dermatitis from allergens or irritants that touch the fingers, such as nickel in rings or certain fragrances in hand creams, can also keep the nail fold skin in a chronically irritated state.
Do Vitamin Deficiencies Cause Hangnails?
This is one of the most common claims you’ll find online, and the evidence doesn’t support it. A review of the research on vitamins, minerals, and nail health found no evidence that supplementation with vitamin E, vitamin C, vitamin A, zinc, iron, selenium, or vitamin B12 improves nail health in well-nourished people or changes the appearance of nails affected by disease. If your diet provides basic nutritional needs, adding supplements is unlikely to prevent hangnails.
Severe malnutrition can affect skin integrity throughout the body, including around the nails. But for the vast majority of people searching this question, hangnails are a moisture and damage problem, not a nutritional one.
How to Handle a Hangnail Safely
The most important rule is never pull or tear a hangnail. Ripping it almost always takes more skin than you intended, deepens the wound, and increases your infection risk. Instead, soak the finger in warm water for a few minutes to soften the skin, then use clean, sharp cuticle nippers to clip the hangnail as close to the base as possible. Sanitize the nippers with rubbing alcohol before and after.
After trimming, keep the area moist. Plain petroleum jelly works well for this. The American Academy of Dermatology recommends it over antibiotic ointments for minor skin wounds, noting that topical antibiotics aren’t needed unless there are signs of infection (increasing redness, warmth, swelling, or pus). Antibiotic creams can actually irritate the skin further and cause contact dermatitis, making the area worse. Choose petroleum jelly from a tube rather than a jar to avoid introducing bacteria.
Preventing Hangnails Long Term
Prevention comes down to keeping the skin around your nails hydrated and protected. A thick, fragrance-free moisturizer or cuticle oil applied after handwashing makes a noticeable difference within a week or two. Pay special attention to this after using hand sanitizer or washing dishes.
Wearing gloves when cleaning, washing dishes, or working with chemicals creates a physical barrier that prevents the repeated stripping of oils. Cotton-lined rubber gloves are ideal because they absorb sweat while keeping irritants out. In cold weather, regular gloves or mittens protect against the dry air that causes so many winter hangnails.
If you get manicures, ask your nail technician to push cuticles gently rather than cutting them. Cutting the cuticle removes the skin’s natural seal against the nail plate, which makes the exposed area more likely to dry out and tear. Keeping cuticles intact is one of the simplest ways to reduce hangnail frequency over time.
