Name one contraindication for performing a manicure.

The presence of fungal infections on the nails or skin serves as a significant contraindication for performing a manicure due to the potential for spreading the infection to the manicurist, other clients, and even worsening the condition for the affected person. Fungal infections can cause severe damage to both the skin and nails, leading to discomfort and requiring medical attention. It's essential for professionals to prioritize hygiene and safety, ensuring that no services are performed on an infected area to maintain a healthy environment for both the client and the technician.

Healthy nails, dry cuticles, and long nails do not present the same level of risk or contamination concern as a fungal infection, and thus do not serve as contraindications in the way that fungal infections do.
