How to Treat Toenail Fungus at Home [+Essential Remedies]
Toenail fungus can be frustrating, persistent, and even embarrassing. If you’re noticing discoloration, thickened nails, or a foul odor from your toenails, you’re not alone. Fungal nail infections, also known as onychomycosis, affect up to 5.5% of the world’s population and are especially common as we age.
But the good news is, there are many safe, simple ways to treat toenail fungus at home, especially if you catch it early. In this guide, we’ll walk you through what causes the infection, the best home remedies for toenail fungus, and how to know when it’s time to seek professional care.
What Causes Toenail Fungus?
Toenail fungus develops when microscopic organisms called dermatophytes or yeasts get into the nail bed, usually through small cracks or breaks in the skin. These fungi thrive in warm, damp environments like sweaty shoes, public showers, and locker rooms. Some common causes and risk factors include:
- Poor foot hygiene or constantly sweaty feet
- Nail trauma (e.g. stubbing a toe)
- Walking barefoot in communal areas
- Wearing tight or non-breathable shoes
- Pre-existing conditions like athlete’s foot, diabetes, or circulatory issues
Early signs include yellow or white discoloration, thick or brittle nails, and sometimes a musty smell. Left untreated, the infection can worsen and spread to other toes or even fingernails.
Note: Fungal nail infections thrive in warm, damp environments. Proper foot hygiene is crucial not only to prevent fungal nail infections but also to help treat them.
Top Remedies for Toenail Fungus You Can Use at Home
Here’s how to treat toenail fungus at home effectively using a mix of natural remedies, hygiene upgrades, and trusted tools. While not all methods work instantly, consistency is key to managing and reversing the infection.
Our top choice for treating toenail fungus at home, this stick is formulated for deep penetration and daily use, which has proven to be a quick treatment for toenail fungus. It’s easy to apply and perfect for targeting the nail bed where the fungus lives. A great choice if you want an easy, effective routine with no mess.
When you first use the Swissker Anti-Fungal Stick, you might notice your nail turning yellow or brown. This is a natural reaction between the fungus and the active ingredients, which actually indicates that the product is working effectively.
Rather than being a concern, this change can be seen as a sign that the treatment is tackling the problem at its source in a quick manner.
Fungus loves thick, hard-to-clean nails. Use the Swissker Heavy Duty Toenail Clippers or the Swissker 360 to keep nails short and allow treatments to reach the fungus more easily.
You need 100% pure tea tree oil or products with high concentrations to make the most out of this remedy.
Usually applied by using a cotton swab, you need to apply twice daily directly to the affected nail and surrounding skin, while making sure the oil reaches the nail bed.
This type of treatment would take at least 6 months or longer to completely cure toenail fungus due to slow toenail growth and the difficulty in eradicating the fungus.
Considerations: Avoid ingestion. Tea Tree Oil is toxic if swallowed. Additionally, you might notice some side effects such as skin irritation, redness, itching, or in some cases, allergic reactions, especially if applied undiluted or on sensitive skin.
Many swear by baking soda for toenail fungus.
The way this works is, you need to make a thick paste using baking soda and water, apply it to the nail, leave it for 10 to 15 minutes, then rinse and dry. Baking soda may help neutralize fungal-friendly acidity.
Keep in mind that this would only work on the early stages of nail fungus, and might take several weeks to see improvements.
Note: Since baking soda stops growth rather than kills the fungus directly, persistence and hygiene are key.
Soaking feet in a solution of one part white vinegar to two parts warm water may help slow fungal growth. For sensitive skin, dilute 1 part vinegar to 2-3 parts water.
Soak for 15 to 20 minutes daily and dry thoroughly after. You need to do this once or twice daily until symptoms improve or resolve.
Please consider that you need to compromise for several weeks to months, as this is more or less the time you need to see fully grown and healthy toenails.
Note: Vinegar is usually more effective for mild fungal infections and as an adjunct treatment rather than a standalone cure.
Garlic has both antifungal and antimicrobial properties. You can apply garlic oil directly or take garlic extract supplements as a natural internal aid.
For Garlic Paste:
- Crush a few garlic cloves to release their juice (2-3 should be enough for two to three sessions)
- Apply the resulting paste from the previous step directly to the affected nail.
- Cover the nail with a bandage and leave it act for about 30min.
- Wash off thoroughly and dry properly.
- Repeat until improvement.
For Garlic Oil:
- Apply pure or diluted garlic oil (if you have sensitive skin) to affected nails, massaging gently to aid absorption.
- Use twice daily for better results.
This kind of home treatment usually takes daily application for several weeks to months to see results.
Topical antifungal creams or sprays are widely available. Look for ingredients like clotrimazole or terbinafine, but remember; these may work better for skin than nails.
Hydrogen Peroxide soaks for toenail fungus make the most out of its antiseptic and oxidizing properties to kill or inhibit fungi on the surface. Please note that evidence or research on effective fungal eradication is limited.
If you want to try Hydrogen Peroxide to eradicate toenail fungus, you need to:
- Prepare a 3% hydrogen peroxide solution (available in most pharmacies)
- Dilute if desired (recommended for sensitive skin).
- Soak affected feet or affected toenails for 10-20 minutes per session (depending on the current stage of the fungus).
- Dry thoroughly after soaking to avoid moisture retention, which can worsen fungal growth.
- Repeat daily or several times per week until seeing improvements.
This approach might take weeks to months of consistent repetition to see improvement. Additionally, this is usually accompanied by antifungal creams or ointments for enhanced and better results.
Fungal spores can hide in your footwear. Disinfect shoes with antifungal sprays and wear moisture-wicking socks. Change socks daily, especially if your feet sweat.

How to Prevent Toenail Fungus
Once you’ve treated it, you’ll want to keep fungus from coming back. Here’s how:
- Keep feet clean and dry
- Trim nails straight across (don’t dig into corners)
- Wear breathable shoes and rotate pairs
- Use antifungal foot powder or spray during humid months
- Avoid walking barefoot in shared showers or pool areas
- Disinfect nail tools before and after use
- Don’t share clippers or socks
When to Seek Professional Help
Home remedies can be effective, especially for mild or early-stage toenail fungus symptoms. But if your infection is worsening or not responding after several weeks, it’s time to talk to a podiatrist or dermatologist. See a specialist if:
- The nail becomes extremely thick, warped, or painful
- There’s bleeding, pus, or signs of severe infection
- You have diabetes or a compromised immune system
- You suspect it might be nail psoriasis or another nail disorder
If left untreated, prescription oral antifungals or even laser therapy might be necessary. To prevent this, early action is a must to prevent long-term nail damage.
