Tea tree oil for nail fungus can take several weeks to many months to show improvement, with some studies noting changes in 14 days but full clearance potentially taking 6 months or longer, often requiring consistent daily application as it's less effective than prescription treatments, though sometimes working well in combination. Patience is key, as it's a slow process, and it might not fully resolve severe infections.
One small study found that pure tea tree oil helped a small amount of people who used it to treat toenail fungus. But other studies on using lower amounts of tea tree oil haven't found it helps treat toenail fungus. Tea tree oil may work well when used with other antifungal medicines.
Biotin, a B-complex vitamin (also known as B7), is essential for healthy hair, skin, and nails. While it doesn't directly kill fungus, it helps strengthen keratin infrastructure, making nails less likely to crack or split—creating fewer entry points for fungi.
How Long Should I Leave Tea Tree Oil on My Nails? Tea tree oil can be left on your nails all day and night.
You can take a prescribed oral antifungal medication to treat the fungus. Options include terbinafine (Lamisil®), itraconazole (Sporanox®) or fluconazole (Diflucan®). You'll need to take the medication every day for several months (or longer).
Eating foods and oils that improve your gut health is a great way to ward off toenail fungus. Doing so also improves your immune system. Try to eat fermented foods like yogurt, sauerkraut, kefir, garlic, onions, and asparagus.
Healthy nails are smooth and even, whereas fungal-infected nails tend to be brittle, crumbly, and ragged. If you observe your nail's texture improving, becoming smoother, and less brittle, it is a clear sign that the fungus is dying. This improvement indicates that your nail is starting to heal and regenerate.
In one study, tea tree oil was applied to the affected nail twice a day for 6 months. The cure rate for toenail fungus was found to be on par with using the cream clotrimazole. Another study didn't show any improvement while using tea tree oil, but it only ran 8 weeks, so perhaps more time was needed.
Undiluted tea-tree oil is a pure natural product. In the presence of atmospheric oxygen but also when exposed to light and higher temperatures, oxidation processes occur leading to the formation of peroxides, epoxides and endoperoxides which have a sensitising potency and may trigger allergic skin reactions.
If toenail fungus (onychomycosis) goes untreated, the nail becomes thicker, brittle, discolored, and may crumble, causing pain and difficulty walking, and it can spread to other nails or skin, potentially leading to serious bacterial infections like cellulitis, especially for those with diabetes or weakened immunity, and can even cause permanent nail damage or loss.
Eggs, especially egg yolks, are the blessing with 10 mcg of biotin per cooked egg [1][8]. That means 2 eggs per day and you're well on the way to your daily biotin content.
In a case report of a patient treated with topical 400 IU vitamin E, there was complete clinical resolution of toenail onychomycosis after 6 months [31].
If you want to try this remedy, apply a bit of Vicks Vaporub to your affected toenails daily. It can still take several weeks to a couple of months for results to appear.
Beyond combating infections, Tea Tree Oil can also contribute to overall nail health and growth. Its natural anti-inflammatory properties can soothe irritated skin around the nails, preventing hangnails and promoting healthier cuticles.
To use tea tree oil for toenail fungus, first trim and clean the nail, then apply diluted pure tea tree oil (mixed with a carrier oil like coconut or olive oil) or a pre-made product directly to the affected nail with a cotton swab twice daily, letting it dry and absorb, for several months until the nail regrows, ensuring the nail stays clean and dry throughout. Always perform a patch test first and be patient, as results take time.
Anecdotal evidence from almost 80 years of use suggests that the topical use of the oil is relatively safe, and that adverse events are minor, self-limiting and occasional. Published data indicate that TTO is toxic if ingested in higher doses and can also cause skin irritation at higher concentrations.
What Are The Best Carrier Oils for Tea Tree Oil?
To permanently kill toenail fungus, you need professional treatment, with oral antifungal medications like terbinafine (Lamisil) being the most effective for clearing the infection, though they require months of use and liver monitoring. Prescription topical creams (e.g., Jublia, Kerydin) and medicated nail polishes (Penlac) are also options, often used with nail thinning or combined with oral meds. Laser therapy can be effective by heating the fungus but isn't a first-line treatment and lacks strong evidence for a permanent cure.
The treatment of fungal skin infections is based on monotherapy or polytherapy using the synergy of the therapeutic substances. Tea tree oil (TTO) may be a valuable addition to the traditional antifungal drugs due to its antifungal and anti-inflammatory activity.
Signs That Your Toenail Fungus is Healing
Improved Nail Texture: The nail becomes smoother and less brittle, with fewer crumbles and breaks. Clear Nail Growth: New, healthy nail growth appears from the base of the nail bed, free of discoloration or distortion.
To know if toenail fungus is dying, check the colour of your nail. Fungal infections often cause nails to turn yellow, brown, or even black due to discolouration and debris buildup. As the fungus clears: The yellow or brown areas may start to lighten.
In the advanced stage, fungal toenail infections can cause severe changes, including: Extensive nail discoloration and deformity. Severe thickening of the nail, making it difficult to trim. Pain and potential complications like secondary bacterial infections or ingrown toenails.
Treatments available
Simply filing down the thickness of the nail can help with these issues. It is easiest to file them when the nails are dry. You should use a separate disposable emery board on the infected nail(s) to avoid spreading the infection to healthy ones.
