What is the primary focus of a consultation form?

The primary focus of a consultation form is to document health history and nail preferences. This form serves as an essential tool for nail technicians to gather important information about a client's health, including any allergies, medical conditions, or past nail treatments that could affect their current service. Additionally, it allows clients to express their preferences regarding nail styles, colors, and services they are interested in. This comprehensive understanding enhances the technician's ability to provide personalized and safe nail care.

The other options address various aspects of the nail service experience but do not encapsulate the primary purpose of the consultation form. For example, while listing nail designs can be a part of the overall service offering, it does not contribute to understanding the client's needs and health, which is crucial for a safe and tailored experience. Calculating service costs is important but is more related to the business side of a salon rather than the client’s individual care. Recording previous technician details may help track service continuity but does not provide the foundational health and preference information that the consultation form aims to collect.
