Final answer:
The area of the strand at the scalp between partings within a pincurl is called the base. It provides the foundation for the direction and angle of the curl. Hair waving methods revolve around the manipulation of the hair root and shaft, which consist of living and dead cells, respectively.
Step-by-step explanation:
The part of the pincurl that is the area of the strand at the scalp between partings within a shape is known as the base. It serves as the foundation for the curl and determines the direction and angle of the curl pattern. Pin curls are typically created for temporary styling, but the hair root and hair shaft play significant roles in both temporary and permanent waving methods. The hair root is located within the hair follicle and consists of living cells. The visible part of the hair is the hair shaft, which consists of dead cells. The hair shaft has three zones: the cuticle, the cortex, and the medulla. Temporary waves are formed by disrupting the hydrogen bonds in the hair's keratin strands, allowing them to reform into a new shape as the hair dries.
