What term refers to the facial form created by an individual's bone structure and hairline?

The term that refers to the facial form created by an individual's bone structure and hairline is commonly referred to as "Face Shapes." This concept encompasses various categories such as oval, round, square, and heart-shaped faces, which are determined by the unique configuration of the bones of the skull and the positioning of the hairline. Understanding face shapes is essential for professionals in beauty and aesthetics, as it helps in tailoring haircuts, hairstyles, and makeup techniques to enhance the features of their clients effectively.

Facial proportion, while related, primarily focuses on the measurements and relationships between different parts of the face, rather than the overall shape formed by the bone structure and hairline. On the other hand, facial structure is a broader term that can include both bone structure and other elements, but it does not specifically denote the various categorized shapes. Lastly, facial symmetry pertains to the balance between the left and right sides of the face, which, while important in aesthetics, is not what is meant by the overall shape determined by bone structure and hairline.
