Artificial nails, such as acrylic and gel nails, can cause fungal infections if they are not attached properly or become loose, allowing moisture to get trapped between the artificial nail and the real nail. Fungi thrive in moist environments and can grow around the trapped water. A group of fungi called dermatophytes are most commonly responsible for nail fungal infections, particularly the fungus Trichophyton rubrum. Nail polish and contaminated equipment at nail salons can also cause fungal infections.
Here are some positive and negative details about nail products and ingredients:
Positive:
- Vinegar: Vinegar contains acid that can inhibit the growth of fungi and bacteria. Try soaking your finger in a 2:1 ratio of warm water to vinegar.
- Vicks VapoRub: An older 2011 study found Vicks VapoRub seemed to have a positive clinical effect on killing toenail fungi. You can try applying a small amount to your finger once a day.
- Tea tree oil: According to Healthline, tea tree oil has antifungal properties and can be applied directly to the affected nail.
Negative:
- Acetonitrile in artificial nail removers: Acetonitrile is a toxic chemical that can cause skin irritation and respiratory problems.
- Methacrylates: Methacrylates are used in artificial nails and can cause contact dermatitis, a type of skin inflammation.
- Toluene: Toluene is a solvent used in nail polish that can cause headaches, dizziness, and skin irritation.
It is important to use nail products safely, following labeled directions and paying attention to any warning statements. If you suspect a fungal infection or other problem with your nails, see a doctor for proper diagnosis and treatment.
