Which of the following is a contraindication for manicure and pedicure services?

Open wounds or infections on the hands or feet represent a significant contraindication for manicure and pedicure services because they pose health risks. Performing beauty treatments in the presence of open wounds can lead to further irritation, infection, or complications for both the client and the technician. Infections can spread easily, and there is a risk of cross-contamination in a salon environment, which is why such conditions must be treated prior to any pedicure or manicure.

In contrast, having dry skin, healthy nails, or moderate calluses generally does not impede the safety or efficacy of nail services. While these conditions may require certain adjustments in technique or products used, they do not specifically contraindicate the services, making them less critical than dealing with open wounds or infections.
