West Virginia Cosmetology Board Practice Exam

Whirls and cowlicks refer to the natural hair growth patterns and their direction. Texture and porosity, density and elasticity, and products used may affect the appearance and health of the hair, but they do not determine the direction of hair growth. Whirls and cowlicks can appear due to genetic predisposition or prenatal development, while other factors such as products used or hair type are influenced by external factors and can be changed or managed. Therefore, the other options are incorrect because they do not directly affect the growth direction of hair.
