If your fingernail is green, you may have a condition called Green Nail Syndrome (GNS), which is caused by a bacterial infection. GNS is characterized by a green discoloration of the nail plate and is most commonly caused by Pseudomonas aeruginosa, a type of bacteria that thrives in moist environments. GNS is often seen in individuals whose jobs require prolonged exposure to water, such as bartenders, dishwashers, and waiters, as well as those with artificial nails or nail trauma. Treatment for GNS typically involves removing any nail enhancements, keeping the nail dry, and allowing the bacteria to disperse on its own without the need for antibiotics or ointments.

Green nail syndrome: an infection caused by bacteria
Green nail syndrome, also known as chloronychia or Goldman-Fox syndrome, is an infection that can develop in individuals whose hands are frequently submerged in water, resulting in discolouration of the nails from shades of green to black. It is caused by the bacteria Pseudomonas aeruginosa, which thrives in damp places with no fresh air circulation, and is therefore commonly found around swimming pools, hot tubs, bathtubs, and showers. The bacteria can also be transferred among clients in nail salons if appropriate hygiene standards are not met.
The syndrome is characterised by discolouration of the infected nail, inflammation of the skin around the nail, known as paronychia, and an odour resembling fruit. The colour may range from light or bluish-green or yellow-green to darker green or black. In some cases, surgical removal of the infected nail may be required. However, this is typically a last resort, and there are other treatment options available.
If the infection is on the surface of the nail plate and hasn't gotten very deep, a quick clean-up may be all that is needed. This can be done by washing your hands with water and an emollient-free cleanser, trimming and filing your nails, and disinfecting them with rubbing alcohol or vinegar. Some sources also recommend soaking your nails in a diluted chlorine bleach solution.
For more severe cases of green nail syndrome, a doctor may prescribe topical or oral antibiotics. Tobramycin eye drops have been shown to be effective in treating the infection. Silver sulfadiazine, gentamicin, ciprofloxacin, bacitracin, and polymyxin B are some of the topical antibiotics that may be prescribed. Oral antibiotics are rarely necessary and are generally a last resort if other therapies have failed.
To prevent green nail syndrome, it is important to keep nails dry and avoid excessive immersion in water. Waterproof gloves or rubber boots can be worn to avoid prolonged exposure to water.

Preventing green nails: keep nails dry and avoid water immersion
Green nail syndrome, also known as chloronychia or Goldman-Fox syndrome, is a rare nail infection that occurs when hands are frequently submerged in water or exposed to chemicals, leading to discolouration of the nails from shades of green to black. It is caused by the bacteria Pseudomonas aeruginosa, which thrives in damp, moist environments with no fresh air circulation. This bacteria is commonly found in swimming pools, hot tubs, bathtubs, and showers, as well as in soil, plants, and animals.
To prevent green nail syndrome, it is crucial to keep nails dry and avoid prolonged immersion of the nails in water. Here are some tips to help you maintain healthy, fungus-free nails:
- Wear protective gear: When engaging in activities that involve water or chemicals, such as cleaning or swimming, wear waterproof gloves or rubber boots to create a barrier between your nails and the moisture. This will help prevent the bacteria from coming into contact with your nails.
- Avoid trauma to the nails: Try to avoid any trauma or mechanical injury to the nails, as this can damage the epidermis seal and make your nails more susceptible to infection. Be cautious when performing tasks that could potentially harm your nails.
- Keep nails trimmed and clean: Regularly trim your nails to maintain short nail lengths. This helps prevent bacteria from accumulating and makes it easier to keep them clean. Wash your hands and nails frequently with soap and water, especially after any water-related activities, to eliminate any bacteria or chemicals that may be present.
- Disinfect and dry your nails: After washing your hands, dry your nails thoroughly. You can also use an alcohol-based sanitizer to disinfect your nails and keep bacteria at bay. If you have naturally oily nail beds, consider using a dehydrator to ensure your nails are completely dry.
- Soak in vinegar or chlorine bleach solution: As a preventive measure, you can soak your nails regularly in a diluted vinegar or chlorine bleach solution. Mix one part vinegar or bleach with three parts water and soak your nails for a few minutes. This will help create an unfavourable environment for the bacteria.
- Use nail whitening products: To restore the natural colour of your nails, you can use whitening toothpaste, baking soda, or nail whitening pens, which are easily available in pharmacies. Apply these products to your nails for a few minutes, and then wash them off.
- Maintain nail health: Keep your nails healthy by nourishing them with vitamin E oil or hand cream. This will help strengthen your nails and make them more resilient against infections. Additionally, avoid the use of coloured nail polish and false nails, as they can trap moisture and create an ideal environment for bacteria to thrive.
By following these preventive measures, you can significantly reduce the risk of developing green nail syndrome and maintain healthy, fungus-free nails.

Green nails and manicures: the role of artificial nails
Green nail syndrome, also known as "greenies", is a rare infection caused by the bacteria Pseudomonas aeruginosa. It is characterised by discolouration of the nails, ranging from light or bluish-green to darker green or black, and is often accompanied by an odour resembling fruit. The condition is more commonly seen in individuals who frequently submerge their hands in water, have damaged nails, or participate in "wet" activities. Artificial nails, particularly acrylic nails, have been linked to an increased risk of developing green nail syndrome due to the thinning of natural nails and exposure to chemicals.
Artificial nails are extensions placed over fingernails as fashion accessories, with some designs mimicking the appearance of real fingernails while others opt for an artistic look. The application process involves filing the surface of the natural nails to create a rough texture, allowing the artificial nails to adhere properly. This filing process thins and weakens the natural nails, making them more susceptible to damage and infection. Additionally, the chemicals used in artificial nail applications, such as ethyl methacrylate, toluene, and dibutyl phthalate, can irritate the skin and lead to contact dermatitis, asthma, and allergies.
To reduce the risk of green nail syndrome and other nail disorders, it is recommended to limit the use of artificial nails and prioritise the health of your natural nails. When applying artificial nails, opt for soak-off gel nails instead of acrylic nails as they are more flexible and less likely to crack your natural nails. Choose a salon that uses an LED curing light instead of a UV curing light to minimise UV radiation exposure. Additionally, request that your nail technician skip the cuticle trimming as cuticles protect your nails and the surrounding skin from infection.
If you notice green discolouration on your nails, it is important to determine whether it is a stain or an infection. If you recently applied a green dip powder manicure, a gentle wash or brushing your nails with whitening toothpaste or baking soda may remove the discolouration. However, if you suspect it is an infection, you can try at-home treatments such as soaking your nails in vinegar or a diluted chlorine bleach solution. Trimming your nails and disinfecting them with rubbing alcohol can also help prevent the spread of the infection. In more severe cases, topical or oral antibiotics may be prescribed by a healthcare professional.

Treating green nails: from whitening products to surgical removal
Green nail syndrome (chromonychia) is a nail disorder characterised by onycholysis and a green-black discoloration of the nail bed. It is often associated with chronic paronychia and exposure to water or moist conditions. While various treatment options are available, addressing this condition can be challenging and often requires the removal of the nail.
If you notice signs of green nail syndrome, it is best to consult a medical professional. A doctor will likely perform a bacterial and fungal culture test to identify the organism responsible for the infection. In most cases, the organism Pseudomonas aeruginosa is identified. Antibiotic sensitivity tests can then be performed to determine the most effective treatment.
For mild cases of green nail syndrome, oral antifungal and antibiotic agents may be prescribed. Topical treatments, such as tobramycin eye drops, have been shown to be effective in reducing nail discolouration. Patients are instructed to apply the medication directly to the affected area of the nail twice a day. After several weeks of treatment, the pigmentation typically fades, although onycholysis may persist.
In more severe or refractory cases, surgical removal of the nail may be necessary. This procedure allows for direct access to the affected area and can facilitate the application of other treatments, such as nail grinding or resurfacing techniques.
It is important to note that green nail syndrome can be challenging to treat, and recurrence is possible. Consulting a medical professional is essential to receiving an accurate diagnosis and determining the most appropriate treatment plan for your specific condition.

Green nails and health: when to seek medical advice
Green nails, or "greenies", are usually a result of a pseudomonas nail infection. This is caused by the bacteria pseudomonas aeruginosa, which thrives in damp places with no fresh air circulation. It is most commonly found around swimming pools, hot tubs, bathtubs, and showers.
The infection is characterised by green discolouration of the nail plate, ranging from greenish-yellow to greenish-black, and an odour resembling fruit. It is usually found in individuals whose hands are frequently submerged in water or exposed to chemicals, or those who have damaged or traumatised nails. The elderly, immunocompromised individuals, and those who have had trauma to a finger or nail are at greater risk of contracting the infection.
If you have green nails, it is important to take action to prevent the infection from spreading. You should start by washing your hands with water and an emollient-free cleanser and trimming your nails short. File or buff off the green parts of the nail and disinfect with rubbing alcohol. Alternatively, you can soak your nails in vinegar or a diluted chlorine bleach solution.
In more severe cases, you may need to seek medical advice. If you are experiencing inflammation of the skin around the nail, known as paronychia, or if the infection is not improving, you should consult a doctor. Moderate cases of green nail syndrome may be prescribed topical antibiotics, while oral antibiotics may be used if other treatments are unsuccessful. In rare cases, surgical removal of the nail may be required.
