Question: 1 / 580

Natural hair wave patterns are influenced by which factor?

Genetics

Natural hair wave patterns are primarily influenced by genetics. The shape of the hair follicle, which is determined by one's genetic makeup, plays a crucial role in how hair grows and its natural wave pattern. For instance, round follicles typically produce straight hair, while oval or asymmetrical follicles can lead to wavy or curly textures.

While hair products can enhance or change the appearance of hair temporarily, and environmental conditions might affect its state on any given day, these factors do not determine the fundamental wave pattern itself. Diet can influence hair health and growth to some extent but does not dictate the inherent wave characteristics, which are established during the formative stages of hair development in the follicle. Thus, genetics remains the most significant factor in determining a person's natural hair wave patterns.
