Nail fungus, also known as onychomycosis, is a common condition that affects both fingernails and toenails—though it’s more often seen in toes. It begins as a small white or yellow spot under the tip of your nail. Over time, the fungus can spread deeper, causing the nail to become discolored, thick, and even start to crack or separate from the nail bed.
While nail fungus isn’t usually dangerous, it can be uncomfortable, embarrassing, and hard to get rid of. It also spreads easily from one toe or finger to another, and even to other people. The good news is that there are several home remedies that can help you manage mild cases of nail fungus. These natural treatments may not work as quickly as prescription medicine, but with patience and consistency, they can help clear up the infection and keep your nails healthy.
Understanding What Causes Nail Fungus
Nail fungus is caused by tiny organisms like fungi, yeast, or molds. These organisms love warm, moist places—like the inside of your shoes or under sweaty socks. Fungal infections can start when fungi enter your nail through small cuts in the skin or a crack in the nail. People with poor circulation, diabetes, or weak immune systems are more likely to get nail fungus.
Some common risk factors include walking barefoot in public showers or locker rooms, wearing tight or damp shoes for long periods, having sweaty feet, or sharing nail clippers or shoes. Nail fungus can also develop after an injury or if your nails are often exposed to water.
What Nail Fungus Looks Like
In the early stages, nail fungus might just make the nail look a little off. You might see a white or yellow spot near the edge of your nail. As the infection spreads, symptoms can include:
-
Thickened nails
-
Brittle, crumbly, or ragged edges
-
Nails that look dull or cloudy
-
Darker color from debris building up under the nail
-
A foul smell coming from the nail
-
Pain or discomfort, especially when wearing shoes
If left untreated, the infection can become harder to manage and may even cause permanent damage to the nail or spread to surrounding skin.
1. Tea Tree Oil As a Natural Antifungal
Tea tree oil is one of the most popular home remedies for nail fungus. It comes from the leaves of the tea tree plant and is known for its antifungal and antibacterial properties. Applying tea tree oil directly to the affected nail can help slow or stop the growth of fungus.
To use it safely, mix a few drops of tea tree oil with a carrier oil like coconut or olive oil. Use a cotton swab or clean brush to apply the mixture to the nail once or twice a day. Make sure your nail is clean and dry before applying. With regular use, you may notice improvements in color and texture over time.
2. Soaking in Apple Cider Vinegar
Apple cider vinegar is acidic and may help stop fungus from spreading. It also helps restore the natural pH of your skin and nails. A simple foot soak made from apple cider vinegar and warm water can soften the nail and make it easier for antifungal treatments to work.
Mix equal parts apple cider vinegar and water in a basin. Soak your feet for 20 to 30 minutes a day. After the soak, dry your feet completely—especially between the toes—and apply a gentle moisturizer if needed. Repeat this daily for several weeks to see results.
3. Baking Soda to Reduce Moisture
Fungus needs moisture to thrive, and baking soda can help keep your feet dry. It doesn’t kill fungus directly, but it may help prevent it from growing by absorbing excess moisture and controlling odor.
You can make a paste by mixing baking soda with a little water and applying it to the affected nail. Let it sit for 10 to 15 minutes, then rinse and dry the area. Another method is to sprinkle baking soda inside your socks or shoes to keep them dry throughout the day.
4. Coconut Oil for Soothing and Protection
Coconut oil contains fatty acids that may help kill certain fungi and protect the skin around your nails. It also acts as a moisturizer, which helps prevent cracking and dryness. While coconut oil alone might not cure a fungal infection, it can be used alongside other remedies.
Apply a small amount of virgin coconut oil to the infected nail two to three times a day. Make sure your feet are clean and dry before applying. Let the oil absorb completely to avoid trapping moisture.
Good Hygiene to Prevent Spread
No matter which remedy you try, good hygiene is key to treating nail fungus and preventing it from coming back. Keeping your nails short and clean reduces places where fungus can hide and makes treatments more effective.
Make it a habit to:
-
Wash and dry your feet thoroughly every day
-
Use clean nail clippers for infected nails
-
Disinfect nail tools after each use
-
Wear clean socks made of breathable material like cotton
-
Let shoes dry out completely before wearing them again
-
Avoid walking barefoot in public places like pools or gyms
Also, try not to cover infected nails with nail polish, as it can trap moisture and make the infection worse.
When To See a Doctor
Home remedies work best for mild or early-stage nail fungus. If your symptoms don’t improve after a few months, or if the infection is causing pain, spreading, or affecting several nails, it’s a good idea to see a doctor. You may need prescription antifungal medication in pill or cream form. In some cases, the doctor may recommend removing part of the nail or using laser treatment to get rid of the fungus.
People with diabetes or poor circulation should see a doctor right away if they notice any changes to their nails or skin, since infections can become serious quickly.
