Going to the nail salon is often seen as a treat—until something goes wrong, like nails turning yellow or green due to an infection called "greenies" or green nail syndrome. This condition, caused by Pseudomonas aeruginosa bacteria, thrives in moist environments, such as under acrylic nails or between the nail and nail bed. While it’s not painful, it’s important to address it promptly to prevent spreading.
Experts explain that greenies are more common among individuals with frequent hand washing, like healthcare workers, bartenders, or waiters, as well as those who bite their nails or have trauma to their nails. salon cleanliness is also a key factor—unsanitized tools or foot baths can spread the infection between clients. Additionally, older adults and those with nail psoriasis are more prone to this issue.
To prevent greenies, it’s crucial to avoid keeping nail extensions on too long, as lifting creates moisture pockets where bacteria thrive. Maintaining good hygiene practices, such as regularly cleaning nails and avoiding aggressive cuticle removal, can also reduce the risk. Choosing reputable salons that prioritize disinfection is another important step in prevention.
If you notice green or black discoloration under your nails, seek treatment promptly. While not typically painful, untreated infections can spread. Dermatologists recommend over-the-counter antifungal treatments and suggest consulting a professional for persistent cases. Quick action ensures the infection doesn’t escalate, keeping nails healthy and looking their best.
Understanding how to prevent and treat greenies is essential for anyone who values nail health or has a higher risk of exposure. By prioritizing cleanliness, staying aware of warning signs
