If you’ve noticed your nails turning a shade of green, you might be dealing with a fungal or bacterial infection. While yellow nails are a more common sign of nail fungus, green discoloration can indicate a more severe issue that needs attention. In this blog, we’ll explore the causes of green nails, how nail fungus plays a role, and natural ways to restore your nail health.
What Causes Green Nails?
Green discoloration of the nails is usually linked to one of the following conditions:
- Fungal Infection (Onychomycosis) – A nail fungus can cause greenish discoloration as it worsens. This often happens when the infection progresses, leading to thickened, brittle nails with an unusual color.
- Bacterial Infection (Pseudomonas Aeruginosa) – This bacterium thrives in moist environments, such as under a nail that has lifted from the nail bed. It produces a green pigment, giving the nail its distinct color.
- Excess Moisture & Poor Hygiene – Nails that remain damp for long periods—especially from frequent hand washing, sweaty feet, or wearing tight, non-breathable shoes—are more prone to infections.
- Artificial Nails & Nail Trauma – If bacteria or fungi get trapped under acrylic or gel nails or if the natural nail is injured, green discoloration can develop.
How to Identify Green Nail Fungus
Symptoms of a fungal or bacterial nail infection include:
- Green, yellow, or dark discoloration
- Thickened or brittle nails
- Foul odor from the nail
- Lifting or detachment from the nail bed
- Pain or tenderness in severe cases
Natural Ways to Treat Green Nail Fungus
If you notice green nails, early treatment is key to preventing the infection from spreading. Here are some natural solutions to help restore healthy nails:
Tea Tree Oil – A powerful antifungal and antibacterial essential oil that helps fight nail infections. Apply a few drops diluted with a carrier oil (like coconut oil) directly to the affected nail twice daily.
Apple Cider Vinegar Soaks – The acidity of apple cider vinegar helps balance the pH of the nail, making it harder for fungi and bacteria to survive. Soak your nails in a 1:1 mix of apple cider vinegar and water for 15 minutes daily.
Oregano Oil – Contains natural antifungal properties that may help clear infections. Mix a few drops with a carrier oil and apply to the nail.
Hydrogen Peroxide – Can help kill bacteria and fungi on the nail surface. Soak the affected nail in a diluted hydrogen peroxide solution (one part peroxide to three parts water) for 10 minutes daily.
Keep Nails Clean & Dry – Moist environments fuel infections, so dry your nails thoroughly after washing, avoid prolonged exposure to water, and wear breathable shoes.
