What term describes hair that forms in a circular pattern on the crown of the head?

The term that describes hair that forms in a circular pattern on the crown of the head is "whorl." A whorl is a specific hair growth pattern where the hair follicles spiral around a central point, resembling a circular or spiral shape. This can usually be observed on the crown and is a natural variation in hair growth that can influence how hairstyles are created and how the hair behaves.

Understanding the concept of a whorl is significant in cosmetology, as it can affect the way hair is cut or styled, particularly for achieving desired volume and movement in hair designs. In contrast, parting refers to the line created when dividing the hair into sections, section refers to a specific subsection of hair, and wave describes a particular texture or pattern formed in the hair that resembles curves or bends. Each of these terms plays a unique role in hairstyling, but "whorl" specifically addresses the unique pattern of circular hair growth.
