As a professional nail technician, it’s important to be knowledgeable about various nail conditions that can affect your clients. One such condition is “greenie nails,” scientifically known as pseudomonas nail infections. Understanding what causes greenie nails, how to prevent them and what steps to take if a client has them can help you maintain a healthy and professional nail care practice.  

• Greenie nails, or pseudomonas nail infections, are caused by the bacterium Pseudomonas aeruginosa. This bacterium thrives in moist environments and can lead to a greenish discolouration under the nail.  

• The infection typically appears as a green, blue-green, or dark discolouration beneath the nail plate. The colour is due to the pigments produced by the bacteria.  

• Trapped Moisture: Pseudomonas bacteria thrive in moist environments. If moisture gets trapped between the natural nail and an artificial nail or between layers of polish, it can create an ideal breeding ground for the bacteria.  
• Poor Application: Improper application of nail enhancements, such as acrylics or gels, can create small pockets where moisture can accumulate.  

• Damaged Nails: Nails that have been damaged or separated from the nail bed due to trauma or improper removal of nail enhancements are more susceptible to infections.  
• Hygiene: Inadequate cleaning of the nail surface before applying enhancements can introduce bacteria.  

• Infected Instruments: Using contaminated tools or products can transfer bacteria to the nail, leading to an infection.         
• Cross-Contamination: Failure to properly sanitise tools between clients can spread bacteria.  

• Clean and Dry: Ensure that the natural nail is thoroughly cleaned and dried before applying any enhancements. Remove any oils, debris or lifted product.  
• Sanitise Tools: Always use sanitised tools and ensure they are properly disinfected between clients.  

• Check-ups: Schedule regular maintenance appointments to check for lifting or damage that could allow moisture to enter.  
• Repairs: Address any lifting or damage to enhancements immediately to prevent moisture from getting trapped.  

• Home Care: Educate your clients on the importance of keeping their nails dry and clean. Advise them to avoid prolonged exposure to water without protective gloves.  
• Avoid Picking: Encourage clients not to pick at their nails or enhancements, as this can create spaces for bacteria to enter.  

• Recognise the Signs: If you notice green discolouration under a client’s nail, it’s important to recognise it as a potential Pseudomonas infection.  
• Inform the Client: Explain to the client what greenie nails are and reassure them that it’s a treatable condition.  
  

• Careful Removal: Gently remove any nail enhancements or polish to expose the affected area. This will help you assess the extent of the infection.  

• Clean the Nail: Thoroughly clean the affected nail with an antibacterial solution. Ensure that all debris is removed and the nail is dried completely.  
• Disinfect Tools: Immediately disinfect all tools used during the removal process to prevent the spread of bacteria.               

• Topical Antiseptics: Recommend over-the-counter antiseptics or antibacterial treatments that the client can apply to the.   affected nail.  
• Consult a Professional: If the infection is severe or does not improve, advise the client to seek medical attention for further treatment.  Normal text.

• Monitor Progress: Schedule follow-up appointments to monitor the healing process and ensure that the infection is clearing up.  
• Reapply Enhancements: Once the nail is healthy again, reapply nail enhancements with extra care to prevent future infections.  

Understanding and managing greenie nails is essential for maintaining a healthy and professional nail care practice. By knowing the causes, practising preventative measures and effectively treating the condition, you can ensure the well-being of your clients and uphold the highest standards of hygiene in your salon.
