Healthy Feet
Our verdict
A pleasant essential-oil blend built around tea tree, thyme, oregano and clove, the natural ingredients with the most research for nail fungus. It can help mild, early cases and the look of yellow, brittle nails if you use it daily for months, but it will not match prescription treatment for stubborn infections.

What is Nail Refresh?
Nail Refresh is a "foot fungus oil" sold through Digistore24. Unlike the nerve formulas on this site, it is not a capsule: you brush or drop it onto the affected nails and the skin around them. The sales page talks about a "fungal force field", meaning the biofilm that fungi build, which is a real reason nail infections are hard to clear. We checked the ingredients on the actual label.

Ingredients and doses
| Ingredient | Amount | What the research says |
|---|---|---|
| Australian tea tree oil | in blend | The best-studied natural option. In a 1994 trial, 100% tea tree oil applied twice daily for 6 months gave results similar to 1% clotrimazole solution, with about 60% of people seeing improvement but few complete cures. |
| Thyme and oregano essential oils | in blend | Contain thymol and carvacrol, which kill nail fungi in lab studies. A small study of a thymol-menthol rub on toenail fungus found improvement in most people and a cure in about a quarter. |
| Clove bud oil | in blend | Rich in eugenol, antifungal in the lab; no good human nail trials yet. |
| Cedarwood, lavender, jasmine | in blend | Mainly fragrance and mild antimicrobial effects in lab tests. |
| Menthol | in blend | Gives a cooling feeling; part of the thymol-menthol rub studied for nails. |
| Sweet almond, rosehip and jojoba oil, aloe vera, glycerin | base | Carrier oils and humectants that soften the nail and skin and may help the other oils spread and absorb. |
| Bearberry extract | in blend | Used in cosmetics for its brightening effect; may improve the look of discolored nails. |
The label lists the ingredients but not their concentrations, so we do not know how much tea tree or thymol you get. The sales page also mentions Manuka honey, which is not on the label. The label itself says "the safety of this product has not been determined" and warns against using it on broken or irritated skin.
Does it work? What the research says
Toenail fungus (onychomycosis) is notoriously hard to clear because the fungus lives under and inside the hard nail plate. Even prescription topical treatments such as efinaconazole cure only around 15 to 18% of nails completely after a year, while prescription tablets like terbinafine do much better. Natural oils sit at the gentler end of that range.
That said, Nail Refresh uses the right kind of ingredients: tea tree, thymol (from thyme) and carvacrol (from oregano) are the natural compounds with the most supportive research. Applied every day for many months, a blend like this can help mild cases that affect only part of the nail, and the oils can make thick, dry, yellow nails look and feel better. Our guide to toenail fungus home remedies covers the evidence in more detail.
Ignore phrases like "in a few days", "complete fungal eradication" and the "7-second fix". A toenail grows about 1.5 mm a month, so a clear nail takes 9 to 12 months to grow out, whatever you use.

Yellow toenails
Tea tree oil for toenail fungusFrequently asked questions
How long does Nail Refresh take to work?
You may see softer, less brittle nails within weeks, but clearing fungus means waiting for a healthy nail to grow out. For toenails that is usually 9 to 12 months of daily use. Take a photo each month to track progress.
Can Nail Refresh be used on fingernails?
The label says to apply it to the affected areas and does not limit it to toes. Fingernails grow faster, so changes show sooner. Keep essential oils away from the eyes after applying.
Is Nail Refresh safe for diabetics?
People with diabetes should not self-treat foot problems without a podiatrist's advice, because small skin injuries can become serious. Ask your podiatrist first.
Is tea tree oil alone just as good?
Tea tree oil on its own has the most research, and it is cheap. Nail Refresh adds thyme, oregano and clove oils plus moisturizing carrier oils, which may help, but there is no head-to-head study. Pure essential oils can irritate skin, so blends with carrier oils are gentler.
