What causes green nails? The most common misconceptions and how to prevent them
Green Nail Syndrome is one of the most common problems nail technicians may encounter in their work. Many people believe that a particular gel polish or artificial nail product is responsible, but in reality, the issue is most often caused by lifting and moisture becoming trapped underneath the product.
The good news is that most cases can be prevented with thorough nail preparation, appropriate product selection, and precise application techniques.
What actually causes green nails?
The green discoloration is not caused by artificial nails or gel polish themselves. The most common cause is the bacterium Pseudomonas aeruginosa, which thrives in moist, low-oxygen environments.
If an artificial nail or gel polish begins to lift, moisture can enter the gap between the product and the natural nail. If this area remains sealed for an extended period, it can create favorable conditions for bacterial growth, which may result in the characteristic greenish discoloration.
Green nails are therefore not typically caused by a defect in the product itself. Instead, they can develop when conditions beneath lifted gel polish or an artificial nail allow bacteria to multiply. This is why clients should not continue wearing lifted or damaged gel polish or artificial nails for an extended period. They should have the affected product repaired or removed as soon as possible.
Prevention is key
Proper nail preparation is one of the foundations of a long-lasting manicure. Thoroughly cleaning, degreasing, and preparing the nail plate helps promote reliable adhesion, which can reduce the risk of lifting. The stronger and more secure the adhesion, the lower the likelihood of moisture getting underneath the product.
The Perfect Nails trio for reliable adhesion
For nails that are more prone to adhesion problems, Perfect Nails professionals often use the following three-step preparation routine:
- Perfect Nail Primer – helps promote reliable adhesion.
- Prep & Clean Cleanser – effectively cleans and degreases the natural nail plate.
- PRO Bond Base – a thin-consistency base gel that provides strong adhesion and can therefore help reduce the risk of lifting.
Thorough preparation combined with professional application techniques can significantly contribute to long-lasting, beautiful nail enhancements.

What should you do if green nail discoloration has already developed?
If you notice green discoloration on a client’s nail, do not cover it with another layer of product. Remove the gel polish or artificial nail and examine the natural nail. If necessary, advise the client to consult a dermatologist. Only apply a new artificial nail enhancement or gel polish once the natural nail is completely healthy.
Proper professional preparation, high-quality products, and regular maintenance all help keep your clients’ nails beautiful and their manicures long-lasting.
