What is a critical aspect to consider when performing nail services on clients?

Considering a client's health history is a fundamental aspect when performing nail services. Understanding a client’s health conditions, allergies, or sensitivities is crucial for ensuring their safety and comfort during services. Certain medical conditions, such as fungal infections or skin conditions, may require special attention or even preclude certain services. Moreover, awareness of allergies to specific products or ingredients can help prevent allergic reactions, allowing for a tailored approach to meet each client's unique needs.

While discussing a client's nail color preference and the availability of products are important for customer satisfaction and ensuring that the desired service can be completed, they do not outweigh the necessity of a thorough understanding of the client's health history. Seasonal trends may influence styles or colors, but the priority should always be on the client's wellbeing. Ensuring that the client is in a healthy condition to receive nail treatments is the foundational step to providing safe and effective nail care.
