Green nails, also known as green nail syndrome or chloronychia, are caused by a bacterial infection. The discolouration is due to the bacteria secreting pigments called pyocyanin and pyoverdin. The bacteria, Pseudomonas aeruginosa, is commonly found in nature, including in water sources, humans, animals, and soil. It flourishes in moist environments, which is why it can often accumulate under false nails. The discolouration can range from light or bluish-green to dark green or black. While it does not cause any health problems, the discolouration can last for several weeks and typically requires treatment with antibacterial or antifungal creams, soaks, or, in rare cases, surgical removal of the nail.

Green nail syndrome causes
Green nail syndrome, also known as chloronychia or Goldman-Fox syndrome, is a nail disorder characterised by greenish discolouration of the nail with onycholysis. The syndrome is caused by an infection with the bacterial organism Pseudomonas aeruginosa, which is found in fresh and salt water, as well as in soil, humans, animals and plants. This bacterium thrives in moist environments and can cause infections in individuals whose hands are frequently submerged in water or exposed to chemicals, or in those who have damaged nails or nails that have experienced trauma.
The greenish discolouration is due to the secretion of pigments such as pyocyanin and pyoverdin by the bacterium. The colour can range from light or bluish-green to dark green or even black. The infection can affect the entire nail or just a small portion of it.
Individuals with weakened immune systems, the elderly, or those who have had trauma to the nail or finger are at a greater risk of contracting green nail syndrome. It is also commonly associated with artificial nails, manicures, heat, dermatitis, ulcerations, occlusions and excess sweating.
In rare cases, individuals with green nail syndrome may accidentally scratch themselves with the infected nail, leading to a self-induced skin or soft tissue infection. However, it is important to note that green nail syndrome does not usually cause any health problems and the bacteria is not contagious once it is dead.
Treatment options for green nail syndrome include the use of antiseptics, antibiotics, and in some cases, surgical removal of the infected nail. Keeping the nails dry and avoiding excessive immersion in water can help prevent the syndrome.

Green nail treatment options
Green nail syndrome, also known as chloronychia or Goldman-Fox syndrome, is a nail infection caused by the bacteria Pseudomonas aeruginosa. This bacteria is commonly found in nature, including in water sources, soil, humans, and animals. It can cause green to black discolouration of the nails, with the colour ranging from light or bluish-green to darker green or black. While it does not usually cause any health problems, the discolouration can be unsightly.
- Keeping the nails dry and avoiding excessive immersion of the nails in water is key to preventing and treating green nail syndrome. Waterproof gloves or rubber boots can be worn to avoid prolonged exposure to water.
- Soaking the nail in rubbing alcohol or vinegar can help to sanitise the nail and prevent the spread of the bacteria.
- Using an antifungal cream, such as clotrimazole, on the hands and around the nail bed for about a week can help to stop fungal growth and eliminate the greenish discolouration.
- Cuticle remover can be used to soften any hardened skin that may trap bacteria, but it is important not to cut the cuticles too close, as this can cause infection.
- Applying a moisturising hand cream after treating the infection can help to keep the skin hydrated and prevent future fungal infections.
- Nail treatments, such as Dr. G's Clear Nail, can be used to keep the nails healthy and prevent discolouration.
- In some cases, surgical removal of the infected nail may be required. However, this is typically a last resort.
- Moderate cases of green nail syndrome may be prescribed topical antibiotics, such as silver sulfadiazine, gentamicin, ciprofloxacin, bacitracin, or polymyxin B.
- Tobramycin eye drops have been found to be an effective treatment for green nail syndrome, with the medication applied to the area of nail separation twice a day.

Preventing green nails
Green nail syndrome, also known as chloronychia or Goldman-Fox syndrome, is a bacterial infection caused by Pseudomonas aeruginosa, a type of bacteria found in nature, including in water sources, humans, animals, and soil. This bacteria flourishes in moist environments and can cause green to black discolouration of the nails. While it is more common in individuals with frequent exposure to water or those with damaged nails, it can be prevented through proper nail care and hygiene practices. Here are some detailed tips to prevent green nails:
Keep Nails Clean and Dry
One of the most important factors in preventing green nail syndrome is maintaining clean and dry nails. Before applying acrylics or artificial nails, ensure your natural nails are thoroughly cleaned and dried. Avoid soaking your nails in water for prolonged periods, as this increases the risk of bacterial growth. If you work with water or spend time in wet environments, consider wearing waterproof gloves to protect your nails from constant moisture.
Practice Good Hand Hygiene
Good hand hygiene is essential to prevent the spread of bacteria. Wash your hands regularly with soap and water, especially before and after any nail treatments. Keep your hands clean and dry, especially after activities that involve water, such as swimming or spa treatments. Allow your hands to air out and avoid constantly covering them with gloves or tight-fitting shoes, as this can create a moist environment conducive to bacterial growth.
Disinfect Nail Tools
Bacteria can easily be transferred through nail tools, so it is crucial to disinfect all tools before and after use. Use clean tools, including nail files, cuticle sticks, and alcohol pads. Disinfect your nail clippers, nippers, and other metal tools to prevent the spread of bacteria. If you visit a nail salon, ensure they follow proper disinfection procedures between clients to avoid cross-contamination.
Treat Any Cuts or Injuries
Bacteria can enter through cuts or breaks in the skin, so it's important to treat any injuries on your hands or nails. Apply antiseptic creams or ointments to minor wounds and keep them covered to prevent bacterial growth. Look for signs of infection, such as redness, tenderness, or swelling, and seek medical advice if necessary.
Use Antifungal Treatments
If you notice any signs of fungal growth, such as discolouration or thickening of the nails, use antifungal creams or treatments. Apply the cream to the affected area and follow the instructions on the label for proper usage and duration. This will help eliminate any fungal infections and prevent further growth.
Choose Reputable Nail Salons
When visiting a nail salon, opt for establishments that maintain high hygiene standards and skilled technicians. Well-trained nail technicians will be able to identify any nail issues and take the necessary precautions to avoid damage or infection. Ask about their disinfection practices and don't hesitate to inquire about their experience and qualifications.
By following these preventative measures, you can significantly reduce the risk of developing green nail syndrome. Remember to pay close attention to your nail health and seek professional advice if you notice any persistent discolouration or other nail abnormalities.

Green nails and health
Green nails, or Green Nail Syndrome, are caused by a bacterial infection, most commonly by the bacteria Pseudomonas aeruginosa. This bacteria is found in nature, including in water sources, humans, animals, and soil. It thrives in damp conditions, which is why it can often accumulate under false nails. The bacteria secrete pigments such as pyocyanin and pyoverdin, which cause the greenish discolouration.
Green Nail Syndrome is characterised by discolouration of the nail, ranging from light or bluish-green to darker green or black. It is also associated with inflammation of the skin around the nail, known as paronychia, and an odour that resembles fruit. While the condition is usually not serious and does not cause health problems, it can make hands look unsightly.
The discolouration typically occurs after the removal of gel polish or acrylic extensions. It can be mistaken for mould, but it is important to note that it is caused by bacteria. Keeping nails clean and dry can help prevent the syndrome, as the bacteria cannot survive on dry, healthy skin.
There are several treatment options available for Green Nail Syndrome. Soaking the nail in alcohol and regularly trimming it back can help dry out the area and prevent bacterial growth. Antifungal creams can also be used to stop fungal growth and eliminate the discolouration. In some cases, surgical removal of the infected nail may be required. While oral antibiotics are rarely necessary, they can be prescribed if other therapies fail. Tobramycin eye drops have been shown to be an effective and safe treatment option.
Overall, while Green Nail Syndrome can be unsightly, it is not typically a cause for serious health concerns. However, it is important to practice good nail hygiene and seek treatment if necessary.

Green nails and manicures
Green nails, or Green Nail Syndrome (GNS), are caused by bacteria called Pseudomonas aeruginosa, which is found in fresh and saltwater. It is also present in soil, humans, animals, and the environment in general. This bacteria flourishes in damp places with no fresh air circulation, which is why it can grow under false nails, just like moss grows in a fish tank if not regularly cleaned.
The greenish discolouration is due to the bacteria secreting pigments such as pyocyanin and pyoverdin. The colour may range from light or bluish green or yellow-green to darker green or black. The condition is not painful and usually affects only one or two nails.
Green nails are often linked to manicures, particularly artificial nails, as the seal between the nail and finger acts as a physical barrier to prevent infection. However, hyper-hydration or destruction of the epidermis can impair the barrier, allowing bacteria to colonize. Artificial nails can also result in a diagnostic delay.
To prevent Green Nail Syndrome, it is important to ensure that your nails are clean and dry before applying any nail treatments. Look for signs of infection on your hands or feet and treat any cuts that could provide an entry point for bacteria. When wearing false nails, avoid soaking them in water for too long, as this increases the chances of fungal growth underneath. If you are going swimming or participating in any activities where your hands will be submerged in water, it is recommended to wear gloves and take extra care when drying off.
If you already have Green Nail Syndrome, there are several treatment options available. It is important to note that artificial nails are not a source of infection, and you can safely apply a fresh set of artificial nails as long as you properly clean the nail plate. You can also soak the affected area in vinegar twice a day for a couple of minutes, clean the nail surface with rubbing alcohol, and trim back the infected part as the nail grows out. Antifungal creams can also be used to stop fungal growth and eliminate the greenish discolouration. In more severe cases, topical or oral antibiotics may be prescribed, and in rare instances, surgical removal of the infected nail may be required.
