Hello, my name is Radina, and I am a master nail technician with over a decade of experience. I created this post to raise awareness about something I’ve been seeing a lot online—nail techs teaching incorrect information about green nail syndrome (also known as “greenies” or pseudomonas).
Recently, I had a client visit my salon—not my work—who came in to remove her acrylics. What I found underneath was concerning. This led me to do more research, and what I discovered on the internet shocked me. There is so much misinformation being spread by nail technicians and influencers with millions of followers. If you are a nail tech or a client, I urge you to read this post carefully before it’s too late.
What is Green Nail Syndrome?
Green Nail Syndrome (GNS) is caused by the Pseudomonas aeruginosa bacterium, which is found in water and soil. It thrives in moist, warm environments and is highly adaptable. Unlike what many believe, it is not a fungus or mold—it is a bacterial infection that feeds on the keratin and proteins in the nail.
What Causes Green Nail Syndrome?
Several factors can lead to greenies:
- Poor Hygiene – Not keeping nails clean can invite bacterial growth.
- Onycholysis – This is when the nail separates from the nail bed, creating the perfect space for bacteria to thrive.
- Lifting of Acrylics or Gels – If enhancements lift, bacteria can get trapped underneath. This can be caused by:
- Improper nail prep (poor cuticle work, inadequate buffing).
- Leaving enhancements on for too long (clients should come back for maintenance every 3 weeks, not 5-6 weeks).
- Product on the skin—which happened in my client’s case.
When you experience lifting, do not seal it with nail glue, do not reattach the nail, and do not ignore it! This will create a sealed pocket, which is the perfect environment for bacteria to grow.
How Does Green Nail Syndrome Progress?
At first, it may appear as a small yellow-green mark on the nail. Over time, it darkens, meaning the infection has worsened. In severe cases, it can cause:
- Pain
- Pus and inflammation
- Secondary infections in the surrounding skin
The longer it’s left untreated, the worse it gets.
What to do – Green Nail Syndrome ‘greenies‘
REMOVE ALL PRODUCT – The first step is to remove any acrylics or gels. This should be done professionally to avoid further damage.
DO NOT FILE OR BUFF THE NAIL – Buffing does not remove the infection; it only weakens the nail and spreads bacteria into the air.
DISPOSE OF CONTAMINATED TOOLS – Any drill bits, nail files, buffers, or gloves that touched the infected nail should be thrown away immediately.
SANITIZE AND STERILIZE TOOLS – Any reusable metal tools (nippers, pushers, clippers, etc.) must be thoroughly disinfected and sterilized using proper salon-grade sterilization methods to prevent cross-contamination.
SANITIZE EVERYTHING – Thoroughly clean all surfaces to prevent bacterial spread.
SEND CLIENTS TO A MEDICAL PROFESSIONAL – As a nail tech, you are not a doctor. Clients should visit a pharmacist or GP for proper treatment.
What Home Remedies Can Help?
While a doctor’s advice is crucial, research shows that pseudomonas bacteria do not tolerate acidity. This means that:
Vinegar soaks (diluted with water) may help, as they create an acidic environment that the bacteria cannot tolerate.
Alcohol (over 70%) can help dehydrate the nail, making it harder for the bacteria to survive. The higher the percentage, the better it will work.
Tea tree oil has natural antibacterial properties that may support the healing process.
However, always consult a pharmacist or GP before trying any treatments at home.
The Dangers of Incorrect Information
Many influencers and nail techs are spreading false information, such as:
- Buffing off the green stain and applying new product (which only worsens the condition).
- Using contaminated nail products (e.g., primers, IBX treatments) without realizing that bacteria can spread in bottles.
- Incorrect cleaning and disinfection practices.
Misinformation is dangerous, especially for immunocompromised clients who are at greater risk of infections. Green Nail Syndrome bacteria can survive on surfaces and even in the air, leading to respiratory issues like pneumonia.
Preventing Green Nail Syndrome
- Proper nail prep – Make sure cuticles are cleaned thoroughly and nails are buffed correctly before applying enhancements.
- Timely maintenance – Clients should return every 3-4 weeks, not 5-6.
- High hygiene standards – Nail tools must be properly disinfected and sterilized.
- Educating clients – Teach clients to recognize lifting early and remove enhancements immediately if needed.
Final Thoughts
This condition is not fungus—it is a bacterial infection that thrives in moist and warm environments. It is caused by poor hygiene, onycholysis, and lifting.
The best way to treat greenies is to remove all product, avoid buffing the nail, and follow strict hygiene protocols. Always seek medical advice before trying home remedies.
