What is defined as a circular growth pattern in the hair?

A circular growth pattern in the hair is known as a whorl. This phenomenon occurs when the hair follicles spiral outward from a central point on the scalp, creating a unique pattern that can vary in size and direction. Whorls are commonly found on the crown of the head and can influence how hair falls and is styled. Understanding whorls is essential for hairstylists as they must consider this natural growth pattern when cutting, styling, or designing a haircut to ensure it complements a client's natural hair texture and growth. The other terms mentioned refer to different hair characteristics: a weight line pertains to the distribution of weight in a haircut, waves relate to the texture and movement of hair, and layers refer to the technique of cutting hair at varying lengths to create volume and shape.
