Which of the following is NOT a primary area of focus in nail care?

Nail care encompasses a variety of practices aimed at maintaining and enhancing the appearance and health of nails. The primary areas of focus in nail care include nail enhancement, which involves techniques to extend or alter the physical structure of the nail; nail health, which pertains to maintaining the natural nail's condition and strength; and nail art, which is the creative aspect of decorating and designing nails.

The notion of cuticle color, while it may relate to the overall aesthetics of nail care, does not constitute a primary focus within the industry. Instead, cuticle maintenance and care are aspects of nail health but do not represent a standalone area of primary focus like the aforementioned categories. Therefore, understanding the core areas of nail care is essential for a nail technician’s practice, and recognizing that cuticle color does not align with these key focuses underscores its secondary nature in the field.
