If you’ve got thick, yellow, stubborn nail fungus that’s been laughing at over-the-counter creams, it’s time to pull out the big guns — the natural kind. This simple two-ingredient remedy uses castor oil and tea tree oil to attack fungus, soften tough nails, and finally let your nails grow in clear again.
Why This Works
- Castor oil is thick, heavy, and naturally antifungal. It penetrates deep into the nail and softens the hardened fungal layers.
- Tea tree oil is one of the strongest natural antifungals on earth. It kills fungus, bacteria, and anything else hiding under your nail.
- Together, they work as a powerhouse duo — the castor oil drives the tea tree oil into the nail where fungus lives.
What You Need
- 1 tablespoon castor oil
- 5–10 drops tea tree oil
- Small glass bowl or bottle
- Cotton socks or gloves
- Nail file (optional, but recommended)
How to Use It
- Wash and dry your hands or feet completely. Fungus loves moisture — don’t give it any.
- Lightly file the surface of the nail.
This helps the oils get down into the nail instead of sitting on top. - Mix the oils.
Stir together the castor oil and tea tree oil in your bowl or bottle. - Apply generously.
Using a cotton ball or your fingers, rub it into the nail, the cuticle, the sides, and underneath the nail tip if possible. - Put on cotton socks or cotton gloves and leave it overnight.
Repeat every night until the nail grows out clear. You’ll see improvement in about 4–6 weeks, but full regrowth can take 3–6 months depending on how bad the fungus is.
Extra Tips
- Trim nails weekly to remove infected growth as the new nail comes in.
- Keep your nails dry — fungus thrives in warm, damp environments.
- Wash socks and gloves in hot water to avoid reinfection.
- Avoid walking barefoot in public showers or locker rooms.
Safety Notes
- Tea tree oil should never be used internally.
- If you have sensitive skin, test a small area first — tea tree oil can be strong.
- Do not use on deep cuts or open wounds.
That’s it! Two ingredients, one simple routine, and the nail fungus doesn’t stand a chance. This is one of those “grandma knew what she was doing” remedies — simple, cheap, and worth the few minutes it takes each night.
